Land and Sea

Visitors to Torbay, where I lived in the 1950s and 1960s, crowded to the beaches when the tide was out, but had to retreat further and further up the sands as the tide was coming in. Then, many left the beach area to go in search of ice cream, sea food, chips and dougnuts - and to play in the amusement arcades.

As a child, I realised that the tidal cycle varied from day to day and also through each month. It was only later that I uderstood that this was the effect of the gravitational pull of the sun and moon on the World’s oceans and that tides were the result of “bulges” and “troughs” in these huge masses of water, reaching their highest when the sun and moon were in alignment in what are termed spring tides. Waves would crash against the shore when the wind was blowing a gale from the east during spring tides and I loved going to the seafront during these storms to watch the cascades of spray – such a contrast to lying on the sand on a warm summer day. After these storms, there would be sand, stones, shells and all manner of flotsam washed on to the promenade behind the sea wall that marked the limit of the blue on a map...

Occasionally, there have been catastrophic breaches in sea defences, as occurred along the coast with the dramatic collapse of the village of Hallsands in Start Bay at the beginning of the Twentieth Century (see above). It was a fishing village, with a sea wall, and was also protected by underwater shingle banks offshore. These shingles were considered very suitable for building purposes and they were dredged, resulting in Hallsands losing a key defence against the effect of storms. The remains of the village provide sombre evidence of the power of the sea as an erosive force and, as a child, I found that looking down on the remains adjacent to the cliff brought a sense of fear and awe. This dramatic location was used in Michael Winner’s film The System [1] for a scene where the characters played by Oliver Reed and Jane Merrow had a romantic liaison – the forbidding atmosphere of the place providing a metaphor for what was to happen in their future relationship.

More recently, there has been serious erosion to the north of Torbay, with the breakthrough of the sea wall at Dawlish and the subsequent undercutting of the main railway line to South Devon and Cornwall. Brunel is widely recognised as a brilliant engineer, but his vision was sometimes unchecked. Certainly, his building of a railway line between sandstone cliffs and the sea was a recipe for trouble and so it has proved on many occasions. The sandstone cliffs of Dawlish (I use the term sandstone to include breccias, where large mineral fragments are embedded in a sandy matrix) are pitted and sculpted by the action of winds and rain and this gives us a clue to another form of coastal erosion; that from landward. Any visitor to the “Jurassic Coast” in southern England is familiar with regular rock falls, as are those who walk under chalk cliffs. They also occur in sandstone areas. There is a good example of such a fall just to the north of Torbay, between Oddicombe and Petitor. This is how the great writer Philip Henry Gosse describes this part of the coast in the 1860s [2]:

Along the margin of a cliff, now steep and sheer, now breaking into an uneven but variously verdant slope, we begin our march, ever and anon pausing to gaze on the smiling scene below. The descent we are just leaving behind, half-covered with the gorse and guelder-rose, is Oddicombe, whose white crescent beach lies below, bounded by the limestone promontory of Petit Tor, which divides the huge precipices of red sandstone close at hand from the bluff coast of the same formation that stretches away to the northward; its ruddy cliffs and bold headlands – Watcombe, The Ness at the mouth of the Teign, the perforated rocks and needles near Dawlish – gradually fading into blue as the coast-line trends away to the eastward, and is lost to the aching gaze somewhere about the boundary of the county.

It is a lovely scene..

Gosse lived in St Marychurch, Torquay, and he made extensive collections of marine organisms between Oddicombe and Petitor, but the sandstone outcrop is different in profile to the one with which he was so familiar. Recent cliff falls have strewn the beach below with masses of rubble (see below), including the remains of houses built on the cliff top to give fine views. Sandstone is a porous rock and consists of mineral grains eroded from older rocks that have become cemented with new mineral deposits and then compressed. In some areas deep within the Earth’s crust, porous sandstone strata provide reservoirs containing oil that we extract after drilling: a similar feature to the aquifers contained within chalk, from which we extract water using boreholes. Needless to say, sandstone that becomes saturated with water, and that is fractured, produces slides like those seen repeatedly at Oddicombe. If you wish to know more of these events, the website of Ian West and Nikolett Csorvasi [3] has many excellent illustrations of the Oddicombe cliffs over time and is well worth browsing.

The original sand that formed the rock may come from deserts, or from sediments at the bottom of seas or lakes. This takes us to the idea of time scales. The coastline of Torbay, so obviously composed to the observer of bands of limestone, sandstone, slates and shales [3], would have looked very different just a few thousand years ago, although the underlying rocks were, of course, always present. Sea level is higher now that it was then and we know that coastal forests have been flooded [4]; remains becoming visible during contemporary low spring tides. If we could see pictures from that time, we would still recognise headlands, although these would be inland and have rather different profiles to the ones we see today. If we go further back in time everything is changed markedly, with the island of Great Britain joined to continental Europe. Before that, Great Britain was part of a huge land mass on a tectonic plate moving around the surface of the Earth, supported on the Earth's magma core.

The Oddicombe cliff falls are easy to recall as they continue and there have been major collapses in the last ten years. We know of the destruction of Hallsands village from contemporary records, and we know of the Torbay forests from the evidence of their remains, although some find it difficult to believe. Events that occurred a million, tens of millions, hundreds of millions and thousands of millions of years ago are quite beyond our understanding. We are sure they occurred, but we cannot comprehend geological time scales. We never will.

William Martin – opponent of the Establishment

William Martin (1772-1851) was “an able mechanic” [1] who worked as a ropemaker and also served in the militia, where he developed a reputation as a highly competent swordsman, often taking part in, and winning, duels [2]. He was also an inventor and, in his biography [2], he includes the following quote, where Mackenzie describes well-known residents of the Parish of Wallsend in Newcastle-upon-Tyne [3]:

“William Martin, the Natural Philosopher,” resides here. He has published, under the patronage of his Grace the Duke of Northumberland, “A New System of Natural Philosophy, on the Principle of Perpetual Motion; with a Variety of other Useful Discoveries.” From the Lord having made man a living soul, by breathing into his nostrils the breath of life, Mr Martin infers that air is the cause of perpetual motion.. ..Mr Martin’s other discoveries are numerous and useful. They consist of a life-preserver for seamen, air-fans for ventilating coal-mines, an inimitable safety-lamp, a plan for curing the dry-rot, cutting canals, and extinguishing fires at sea; also an improved velocipede, a suspension bridge, &c &c. But unfortunately, though under such noble patronage, his inventions have not been brought to a successful termination; and most of them have been stolen from him by unprincipled men! Mr M. did, however, obtain, in 1814, a silver medal and ten guineas from the Society of Arts, for his invention a of a spring weighing machine...

Based on this description, what are we to make of William Martin? His Perpetual Motion Machine was exhibited in London in 1808 and among those who saw it was Charles Hutton FRS, the famous mathematician [4]. He complimented William on the elegance of construction, but concluded that the pendulum of the machine continued to swing because of the influence of magnets. William, quite rightly, denied this, but chose not to explain that a hidden tube connected with the outside of the building allowing atmospheric air to be drawn to and fro, just beneath the ball at the base of the pendulum. William himself gave a description of the machine in 1825 but it is difficult to imagine its construction without seeing a version of it. As to his other inventions, Balston [4] concludes that “..William’s safety-lamp and weighing-machine were of real value..” and it may well be that the lamp was superior to those of Davy and Stephenson that became most widely known. Among William’s less successful inventions was the “Northumberland Eagle Mail”, a type of dandy horse bicycle propelled by the feet of the rider (see below – there were many versions and we do not know who copied whom). William used this to ride from town to town giving lectures on Natural Philosophy, although Balston [4] describes the failure of one demonstration: “…on the Town Moor, he got excessively hot propelling it over the rough ground and was pelted with mud by the spectators.”

Clearly, William was thick-skinned as well as having a talent for invention, although he continued to be irked by what he felt was a lack of recognition and this set him against the scientific Establishment. He clearly retained a liking for duels, although not of the kind in which he was so successful as a younger man. Seccombe [1] writes:

He founded the Martinean Society, based on opposition to the Royal Society, and particularly hostile to the Newtonian theory of gravitation, against which he harboured a growing antagonism, which ultimately embraced all men of science. Styling himself ‘anti-newtonian’, Martin began giving lectures, first in the Newcastle district and from 1830 throughout England. Throughout these years his voice was heard at many meetings, ranting against scientists in general. He was inevitably drawn to the annual gatherings of the British Association for the Advancement of Science, the butt of his polemic The defeat of the eighth scientific meeting of the British Association of Asses, which we may properly call the rich folks’ hopping, or the false philosophers in an uproar (1838).

In addition to his views on science and scientists, William also pronounced on politics and economics (I apologise on his behalf for the sexism) [4]:

He believed that there was much more wisdom among the poor than among the rich and thought that only poor men should be elected to Parliament. The college-bred man, he said, could make great speeches, but a man could be a wonderful speaker without being wise. He scouted the idea that England was over-populated, and said that shortage of food and employment was wholly due to the mismanagement of the rich. He advocated Government works – improving roads, reclaiming waste land, planting forests, and enclosing commons – as the cure for unemployment. He proposed a two-shilling income tax on all incomes above £100, and was ready to compensate the taxpayers by giving each of them a gold medal or star to wear, with the total amount of his taxes engraved on it.

It’s no surprise that the wider Establishment also rejected him after such an attack. As we look back at William Martin, this quote from a review of his book A New System of Natural Philosophy in The Newcastle Magazine of January 1822 concludes [5]:

When Mr Martin’s volume is read in the 21st century.. ..the wise of that day will doubtless exclaim that, though not quite so extensive as the universe, his works are equally inexplicable. After a quotation or two, and a few exclamations about the greatness of God, and the raptures of our author at the sight of Jupiter, Saturn, and Venus.. ..Mr Martin concludes with the republication of Pope’s universal prayer, which, an ill-natured critic would say, is certainly, though not the most amusing, by far the most instructive piece of philosophy in the book.

That’s right up there among the best damning reviews one could get, but I haven’t read William Martin’s book so I am not in a position to judge. However, having been trained as a scientist, I am conscious of the need to avoid exaggeration and dishonesty, although there are cases of scientists who bend the rules to get exposure. Although he was not trained as a scientist, William Martin provides an example of someone who had talent, but did not follow this creed, yet it is easy to warm to his stand against the political Establishment and the role of the “ruling class”. His ideas on economics also have a contemporary feel.

Do we appreciate characters such as William Martin and, more importantly, should we pay them much attention? How extraordinary, too, that William and two of his brothers all became famous in their day: Jonathan (1782-1838) was a notorious arsonist, driven by his religious beliefs [6], and John (1789-1854) a well-known artist who has works in the collection at Tate Britain.

Changing our appearance

Modern Biology is dominated by molecular approaches and, especially, the role of genes in evolution and in medicine. In contrast, my degree studies in Zoology in the 1960s were based on the structure and function of a wide range of whole organisms. However, we were introduced to the importance of genes and the way that they interact with the environment (whether within a single cell, within an individual, or outside an individual) through the phenotype (the appearance created by gene expression). We learned that changes in the genotype (the whole genetic makeup, also called the genome) that occurred by chance mutations resulted in changes in the phenotype and that a changing environment allowed the selection of different phenotypes (and thus genotypes) that would be favoured. It is the process of natural selection that Darwin propounded, with the addition of an explanation based on genetics. In the natural world, the process whereby a genetic mutation results in a successful phenotype may take thousands of years to spread through a population: much less in primitive organisms with short, or very short, life cycles.

It was a relationship that always stuck in my mind, although it had little influence on my research and teaching. Some of my research collaborators worked on phenotypic plasticity (different environmental conditions allowing the expression of different parts of the same genotype), so I had that idea, and could see how it applied to animals such as the arctic hare and the ptarmigan that change the colour of their coat/plumage from summer to winter as their environment changed from multicoloured to white. This is clearly under genetic control and requires changes in the physiology of each animal, driven by the influence of environmental cues. There are many more examples in the natural world.

The genotype-phenotype-environment relationship is of great interest to humans, although we may not know of it as such. While recognising that we are created by our genes, it is our phenotype that most interests us in Western countries - the way we look. Of course, we add to that by changing our external appearance frequently (unlike arctic hares and ptarmigans) by using clothes and other coverings. Much attention is given to the hair that grows on parts of our bodies and, recently, on body ornamentation in the form of tattoos. However, it is our shape, and the appearance of different body parts, that most affects us, as these are not easily changed in hours.

Unfortunately, not everyone is satisfied by their body and surgical procedures are used to change our phenotype. These include face lifts, breast enlargement or reduction, hair transplants, modifying parts of the face (like cheek bones and noses), and many others. Cosmetic surgery is invaluable after accidents or major illness, but the modification of appearance for vanity is narcissistic; yet so important to those that spend large sums of money on these procedures. Recently, a contestant on Love Island, a reality TV show in the UK, admitted to having extensive cosmetic interventions on various parts of her body; the cost being estimated at £25,000. She stated “I didn’t take all the decisions (about the operations, fillers, etc.) because I was trying to be a role model. I did it for me and no-one else.” [1]. In the article (see above) she didn’t explain why the results of the procedures made her feel better. The legendary Jocelyn Wildenstein probably spent a lot more on her surgical enhancement (see below) and she has stated that she is very pleased with the results, as she always wanted to look like a large cat. I have no idea whether she knows that others find her appearance monstrous.

In medicine, we are now looking to alter genotypes to prevent serious illnesses, or as a means of treating existing ones, with the exciting development of pharmacogenetics allowing drug treatments that are tailored to individuals. Very large sums of money, and much effort, go into this and the results in a few areas are highly promising. I wonder how long it will be before changing our genotype becomes an acceptable way of altering our phenotype and thus the way we look? It is unlikely to be soon, as so many genes are involved, and it may only be effective during early development, when adult features are beginning to form. Designer babies anyone?

At the opposite end of the age spectrum, we are also investing heavily in studies of ageing. Genetic engineering based on the results of these studies could promote an appearance of agelessness; replacing the cosmetics and cosmetic procedures on which we spend so much money. Then, if we can reduce the appearances of ageing, can we genetically engineer individuals to not age and thus not die? Surely that will never happen?

So, what of the third factor in the genotype-phenotype-environment relationship? We are mostly concerned with our social environment and, through research, in the environment within individuals. Our progressive destruction of the natural environment, a factor in both mental and physical health, might make selection of the phenotypes from altered genotypes irrelevant. But then, our interest is in humans, and the superficiality of humans, above all else.

The power of religious conversion

A religious conversion is usually transformative. Having been brought up as a Christian, and having attended evangelistic rallies, I have often wondered what happens in people’s minds during that process. Some insights are given in “testimonies”, but these are often full of clich├ęs and not very helpful to understanding.

Jonathan Martin (above) gives a description of his conversion in his autobiography [1]:

The first Love feast [a gathering of Christians to share bread, water and prayer] that I attended was at Yarm; my soul was dismayed and filled with unbelief, and I wept sore and would not be comforted. My brethren fell on their knees and prayed with me, but their prayers were of no effect. I went home and went to bed sorrowful, not having found the blessing of which I had aforementioned dreamed..

..My religious friends were often enquiring if I felt the Witness of the Spirit, to which I replied that I did not and would not, till the time came.

At the end of five months, I took the Sacrament in the Church at Stockton, and leaving it at half past one o’clock, I hastened to Yarm, where the lovefeast was to commence at two o’clock. I had only had an hour to go four miles, but I was running for a prize, and was determined not to be late..

..I arrived before the first prayer was finished, and was not five minutes on my knees till the Lord set me at full liberty, and here too he shewed me that I had indeed met with the people among whom I must find my way to glory..

..The next night I was invited to a Prayer Meeting at Norton, the Room we occupied was nearly full, and while the Class Leader was giving out a Hymn, The Spirit of God came down in such abundance into my heart, that I was ready to leap over the Table for joy.

Clearly a profound, and transforming moment for Jonathan, but who was he and what were the consequences of his conversion?

Fenwick Martin, Jonathan’s father, was a tanner (but had many other jobs) and was known as an excellent swordsman. He eloped to Gretna Green with Isabella Thompson, the daughter of a landowner who did not approve of Fenwick, and they went on to have thirteen children, only five of which survived to adulthood [2]. The five children were all born in different towns and villages, a result of the itinerant lifestyle led by their parents. Fenwick loved travelling from place to place [2].

Jonathan was the third child - a sister and brother were to follow him – and he had a birth deformity, being tongue-tied. This was cured by cutting the membrane holding the tongue to the floor of the mouth when he was "in his sixth year", something that resulted in a speech impediment for the rest of Jonathan’s life [2]. This early experience must have troubled him, as his inability to speak as a young child meant that he was isolated and he often walked alone in the countryside. He was self-educated and could read and write, but he was apprenticed to a tanner in Hexham, following one of this father’s professions. He also took after his father in having wanderlust and he was determined to see something of the world when his apprenticeship ended in 1804. In London, he was press-ganged into the Royal Navy, serving on the H.M.S.Hercules (where he was amazed that the Captain ordered bands to play on a Sunday, offending his religious beliefs) before being transferred to another ship that had been captured as a prize. At Cadiz:

..he had many narrow escapes from the shore batteries, and this made him “begin to see his lost ruined state as a sinner, and to cry to God for mercy and salvation, hoping He would spare him to return to his native land, when he would join himself to the people of God”, i.e. the Wesleyan Methodists [2].

Shortly after, Jonathan jumped ship and sailed in a merchantman for Egypt and returned via Sicily to Portsmouth, where he was paid off. In this last journey, a rogue wave in the Bay of Biscay nearly sank the ship, a scene illustrated in Balston’s biography [2] (see below). From Portsmouth, Jonathan travelled to London and then back to the North-East of England where he returned to work as a tanner. He married in 1814 and had a son, Richard, who was named for one of Jonathan’s brothers.

We now reach the time when Jonathan went to the love-feast in Yarm and his conversion, as described in the autobiography. He went on to develop an intense dislike for the Church of England and his life became guided solely by messages from God, sometimes coming in dreams [2]:

The Wesleyan Methodists were so alarmed by his conduct that they expelled him from their Society, and Mr page [the tanner] dismissed him from his employment. But he felt the peace of God in his soul, and was not discouraged.

Over the next months he moved around to get work and maintained his hostility to preaching in the Church of England, even attempting to interrupt sermons. On hearing that the Bishop of Oxford was to hold a confirmation at Stockton, Jonathan decided to attend. He had previously borrowed an old, broken pistol from his eldest brother, which was discovered by his wife. On being asked what the old weapon was for, Jonathan replied that it was to be used to shoot the Bishop. His wife subsequently removed the pistol and Jonathan went to the service in Stockton without it – however, she reported Jonathan’s “intention” to the Church authorities and he was subsequently arrested and appeared before the Justices at Stockton who, on getting some typically strange answers to their questions, “ordered him to be confined in a madhouse for life”. Jonathan was then conveyed to the West Auckland lunatic asylum. 
Balston [2] gives us an account of Jonathan’s life in the asylum, where he suffered at the hands of both fellow inmates and, on occasion, from the asylum owner. He was transferred to the asylum at Gateshead, where he had an ambivalent relationship with the owners, just as he had at West Auckland, and eventually escaped from there via the roof (see above). Jonathan wandered through the countryside and was exhilarated at being free, visiting a distant relative of his mother, who made him welcome. Unfortunately, his wife had died of breast cancer in 1821, so he could not return to her and he travelled widely through the North of England and Scotland. Jonathan was able to earn some income as a tanner and from hawking copies of his autobiography while on his journeys. The first edition was published while Jonathan was in Darlington in 1825, a second being printed in Barnard Castle in 1826, with a third in Lincoln in 1828.

It was in Lincoln that he married Maria Hudson and Richard, who had been lodging with Jonathan, was then sent to a boarding school. Jonathan was readmitted to the Wesleyan Methodist Society and he retained the fervour, and convictions, so clear to him at the time of his conversion. With Maria, he travelled to York, arriving on 26th December 1828, and it was Jonathan’s activities in York that led to his widely-known notoriety. It began with a series of letters (all with Jonathan’s idiosyncratic spelling [that had been corrected in the autobiography]) attacking members of the clergy in the Church of England for their indulgent lifestyles and complacency, but none received a reply. Jonathan was further angered by this, stating [2]: “I found the Lord was determined to have me show this people a warning to flee from the wrath to come.” 

He devised a plan to carry out his threat and, on 1st February 1829, he entered York Minster and, after kneeling in prayer, was directed to go to the bell loft, where he remained when the Minster was locked up for the night. Balston [2] details what happened next and, in summary, these consisted of Jonathan gathering flammable materials and setting them alight – all guided by the reassurance and direction that he gained from God through prayer. He escaped though a window and the resultant blaze burned through the night, destroying part of the roof and the interior of the eastern part of the Minster, including the Archbishop’s throne.

After this disaster, a group of clergy and magistrates met to discuss how the fire occurred. They concluded quickly that the fire was the result of arson, the rope ladder used by Jonathan to climb to a window having been discovered, and the culprit was identified after questioning people who had met him. The letters were also produced and an arrest warrant for Jonathan was issued, with a reward of £100 for his capture. He was eventually tracked to Codlaw Hill and was taken to the “House of Correction” in nearby Hexham. From there he was taken to the jail in York and appeared before the Grand Jury at the Guildhall on 23rd March 1829, an event so popular that there was a melee over the available seats and it was agreed that a more fitting location would be the County Assizes, commencing on 30th March.  On being charged with setting fire to the Minster, Jonathan replied [2]: “It was not me, my Lord, but my God [that] did it.” The trial proceeded, with many witnesses who knew Jonathan being called; the letters he had written being admitted as evidence. The jury returned a verdict of “not guilty on the grounds of insanity”, with Jonathan detained during His Majesty’s pleasure. He was sent to London and was eventually confined in the Hospital of St Mary of Bethlehem (“Bedlam”), dying there in 1838, aged fifty-six.

Was Jonathan insane? There are many cases where people commit acts after praying, or believing that they are receiving a message from God. Does this mean that all those who act on such impulses are insane? Would Abraham have killed Isaac on the orders of God if an angel hadn’t intervened [3]? Did Jonathan Martin have a breakdown, as Matthew describes it in his biography [4]?  Do visions and these powerful religious impulses come from mental breakdowns? Does religious conversion follow a kind of breakdown, or heightened emotional state, where rational thought is suspended?  When does “hearing God” become “hearing voices”? I ask these questions as an atheist and I’m puzzled.
