Dry Storeroom No. 1 (5 page)

The geography has changed profoundly since I first entered the British Museum (Natural History). Science departments have been rehoused—my own department, Palaeontology, being the first of them. I had to say goodbye to my polished cabinets, balconies and nineteenth-century haven to relocate to the third floor of the rather characterless modern block tacked on to the eastern end of the old building, an extension as typical of the utilitarian (some might say cheap) 1970s as the old building had been typical of the Victorian love of detail. The relevant minister, Shirley Williams, opened the new wing in 1977. Moreover, the space was generous, and necessary, because the palaeontologists had formerly been dotted all over the place; now they could be together. The Zoology Department, including all those sad fish, has been moved to the much more glamorous Darwin Centre at the western end of the building. Farewell to the Spirit Building, and to its dusty and slightly romantic gloom. Only my old friends the molluscophiles are still secreted in their old haunts in the basement. Nonetheless, the sense of the three-dimensional maze has not been lost. The whole thing just got bigger. Gormenghast lives on.

On one of my forays through the basement I came across a door that I had not noticed before. This was on a corridor with an air of being seldom visited on one side of which were tucked away the osteology collections—bones, dry bones, where oxen strode naked of their skin and muscles, and great bony cradles hung from the ceiling, the jawbones of whales. Here, ape and kangaroo met on equal terms in the demotic of their skeletons, with no place for the airs and graces of the flesh. Strange though these collections might seem, they were as nothing compared with what lay behind the mysterious door opposite. For this was Dry Storeroom No. 1. Neglected and apparently forgotten, this huge square room entombed the most motley collection of desiccated specimens. Fishes in cases were lined up species by species in their stuffed skins; they were presented in faded ranks like a parade that had forgotten the bunting. At one end there was a giant fish that seemed to have been cut off mid-length, such that the posterior part of its body was apparently missing, and it had a silly little mouth out of proportion to its fat body. It was a sunfish, and its cut-off appearance was entirely natural—a faded notice attached to it proclaimed it was the “type.” Elsewhere there were odd boxes, one of which contained human remains, laid out in a kind of slatted coffin. The shells of a few giant tortoises hunkered down like geological features on the floor. There were sea urchin shells, and some skins or pelts of things I couldn’t identify. Most peculiar of all, on top of a glass-fronted cupboard there was a series of models of human heads. They were arranged left to right, portraying a graded array of racial stereotypes. One did not have to look at them for very long to realize that there was a kind of chain running from a Negroid caricature on one side to a rather idealized Aryan type on the other. This was a remnant of an old exhibit, heaven knows from what era, with more than a sniff of racism about it. Dry Storeroom No. 1 was a kind of miscellaneous repository, a place of institutional amnesia. It was rumoured that it was also the site of trysts, although love in the shadow of the sunfish must have been needy rather than romantic. Certainly, it was a place unlikely to be disturbed until it was dismantled. I could not suppress the thought that the storeroom was like the inside of my head, presenting a physical analogy for the jumbled lumber-room of memory. Not everything there was entirely respectable; but, even if tucked out of sight like suppressed memories, these collections could never be thrown away. This book opens a few cupboards, sifts through a few drawers. A life accumulates a collection: of people, work and perplexities. We are all our own curators.

The Naming of Names

In 1976 I almost burnt down the Smithsonian Institution in Washington, D.C. If I had succeeded I imagine that I would now be one of the most famous scientists in the world. Thirty years ago I was a pipe smoker, and the study cubicles in the National Museum of Natural History in the Smithsonian allowed scholars to puff away at their pipes while looking down the microscope. It somehow seemed an appropriate thing to permit. Behind the scenes at the Smithsonian lies a similarly vast labyrinth to that in our Natural History Museum and here, too, are ranks of collections, quietly minding their own business until a visiting expert re-examines them in their labelled drawers. I was interested in looking at trilobite specimens collected years before by one of their staff, E. O. Ulrich. I had my microscope in front of me, and a line of specimens to one hand, while the other picked up the pipe from time to time and waved it about. It was about as contented a scene as could be imagined. At the end of the day I did what pipe smokers do, which is to tap out the dead pipe into the metal waste-paper bin in the corner of the room. The only problem was that the pipe was not completely dead; I had deposited smouldering scraps of Erinmore Mixture among the discarded pieces of paper in the bin. I shut up for the night and went home. Half an hour later, a passing security man noticed billowing smoke arising from my cubicle; fortunately, the fire was quickly extinguished. It might have been a different story had the receptacle been a woven basket. I overheard mumbled gossip about me for the next few days.

Had I destroyed the United States’ national collections of natural history the damage would have been irreparable, not just for that country but for the world. The most important single feature of the great collections is that they form the basis for naming the living world. They are the reference system for nature. The curated specimens are the ground truth for the scientific names of animals, plants and minerals. The naming of organisms is called taxonomy, and their arrangement in classificatory order is called systematics. All those cabinets I passed when I explored the Natural History Museum in London were the storehouses for the still-growing catalogue of what is now often termed biodiversity, the richness of the living world. Although it achieves a lot besides, the basic justification of research in the reference collections of natural history museums is taxonomic. So if my Erinmore Mixture had sparked off a major conflagration, much of the basis for the names given to fauna and flora around the world would have gone up in smoke. It would have taken years to sort out. Some museums were bombed during the Second World War, such as the Humboldt Museum in Berlin, and lost many specimens; the resulting taxonomic confusion is still being worked out. That is why museums place such emphasis on the security of their collections; it is an acknowledgement of their permanence: hence the special keys and the security codes.

The taxonomic mission can be briefly stated: to make known all the species on Earth. It sounds easy. This is, of course, only the beginning of finding out about life, because there lies beyond identification so much more, such as how animals live—their ecology—or why there are different species in different parts of the world. Often the taxonomy is inextricably entwined with these other aspects; for example, when two closely related species may be distinguished by having subtly different ecology. European ornithologists will know the instance of the exceedingly similar marsh (
Parus montanus
) and willow (
Parus palustris
) tits, which are readily distinguishable only by their songs. Recognition of species is always the first step in understanding the complex interactions of the biological world. Just as you need a vocabulary before you can speak a language, so it is necessary to have a dictionary of species before you can read the complex book of nature.

Nor is the taxonomic mission as simple as it sounds. There are a few groups of organisms—birds and mammals come to mind—where large size and intensive study over many years means that the vast majority of species have been named and described. Even here there can be surprises, as when a new species of large ungulate mammal was discovered in the jungles of Vietnam a few years ago, or when in 2005 a pristine part of New Guinea was explored for the first time and a rare bird of paradise brought “back from the dead.” Bats are turning out to have many more species than was originally thought. I went with a research student into the cloud forest of Ecuador to see a new bat species with the longest tongue in the world that had apparently evolved to feed from (and pollinate) an extraordinary flower with a matching long corolla. It is illustrated in the colour plates. But as a rule there are very few new mammal or bird species to discover, and global concern is rather with conserving those that are known already: by any standard this is a big enough matter.

With other groups of organisms the story is different. The insects are the most obvious example: small, teeming and unnoticed, they fill almost every habitat on Earth. I will choose one example, from a cast of thousands. You have to be a special kind of person to love fungus gnats, but if you look at mushrooms growing in woods you will certainly see these tiny insects flying around the fungi. They are abundant. Most of us encounter these particular creatures as irritating “wormholes” occupied by their larvae that might spoil an otherwise nice-looking field mushroom. But they still fulfil an important function in nature, and they provide a foodstuff for insectivores in their turn. They are a link in the chain. But how many species are there? And how do you tell them apart? Do they feed on lots of different fungi or are there specialists for particular kinds of fungi? All these questions require the attention of a knowledgeable taxonomist, a microscope and skill. Tiny differences in the wings or the hairs on the legs may be crucial in the identification of a species. With luck, expertly identified specimens will finish up as collections in a cabinet marked Family Mycetophilidae (“mushroom lover”) in the Natural History Museum. As to how many species there are, well, at the last count there were 531 different fungus gnats in the United Kingdom alone, and more being added all the time. It is scarcely surprising that there are many more species still remaining to be discovered in the wild. If a new bat can be discovered in Ecuador’s cloud forest, it is likely that nobody has even looked at the fungus gnats. And each species will have its own ecological story to tell, another biography to add to the narrative of the natural world. When it comes to status as a species, size doesn’t really matter.

At this point one is supposed to put the beetles centre stage, because what is true of the fungus gnats is true of beetles many times over. The geneticist J. B. S. Haldane remarked, when questioned by a cleric about the putative properties of God, that one sure characteristic of the Almighty would be “an inordinate fondness for beetles” this has become one of biology’s well-worn phrases. It is no less appropriate for all its familiarity. One-fifth of all species are probably beetles, most of them leading inconspicuous lives. There are somewhat fewer than half a million species of these animals named so far. When in the 1980s Nigel Stork collected insect species from the tropical forest canopy, he found that many of them had never been collected before—and that many of them were beetles. These were new species, needing a scientific name. It is a massive task just to make an inventory of beetles, let alone understand their biology.

Outside the insects, we can go on to tiny organisms like nematode worms, or smaller still to single-celled organisms—a whole universe of different biological organisations—or down to the smallest of all, the bacteria, where it may be necessary to use biochemistry or genetics to recognize species for what they are. Or we might go down into the depths of the sea where a start to sampling has hardly been made, and every animal is a specialist adapted to eternal darkness and great pressure. Nobody knows how many undiscovered species there are down there, although it is certain that there are many: a single trawl can reveal a dozen new crustaceans. A 2007 report from the Antarctic revealed many extraordinary new crustaceans that had escaped the attention of all marine biologists. There are huge numbers of unknown fungi—tiny ones many of them, or inconspicuous species hidden away under rotting logs. Something like two million species have been named and recognized, and there are certainly an equal number still to name. Many scientists believe that there may be five times that number, considering the habitats that are still so poorly known. There is so much to do, and so few people to do it. An estimate of the number of people who might know about systematics in the whole world came to only about four thousand. And I have not even mentioned fossils: a history of life also needs the myriad characters in the narrative of extinct animals and plants to be identified. So far, there is no indication that we are anywhere near the end of that process, even regarding the largest animal fossils, such as dinosaurs. The labyrinthine anatomy of the Natural History Museum might after all be appropriate to the world it represents, for the realm of nature is truly a castle of Gormenghast, with its half-explored wings and obscure corners where few venture.

Many of the people whose names I had noticed on their offices or cubicles were soldiers in this war against ignorance. They were unseen heroes in a battle against insuperable odds, a battle unnoticed by the million people who pass through the public galleries. A lifetime of endeavour in these cells might be rewarded with the accolade of becoming an “authority”—even a “world authority.” This means that the scientist and scholar knows as much about his chosen area as anyone—his views will be sought out on the identification of his organisms by scientists in Minneapolis, Manchester or Mombasa, be they beetles or bats. The notion of authority is a curious one. It is not something that one says of oneself, so I have never heard anyone introducing him-or herself as “the authority on mushroom gnats.” On the other hand it is quite often used to describe a fellow scientist: “Dr. Buggins, the authority on toads” and so on. Just working in a museum like the Musée d’Histoire Naturelle in Paris or the American Museum of Natural History in New York is no guarantee of becoming an authority. This distinctive label is hard earned by publishing and writing on the chosen subject, although it would be difficult to define a kind of critical mass of words when a young scientist passes into an authority. There is certainly no sex discrimination in the title these days, as there would have been a hundred years ago. It is one of those titles that cannot be bought, nor traded, nor given away; it just arrives, like grey hair.

Taxonomic scientists are often referred to by their speciality. Thus “bat man” would be an expert on bats, “worm man” on worms, and an anthropologist would naturally be a “man man.” I suppose I was known as “trilobite man,” even though it sounds like a creature from a horror film (“worm woman” sounds even worse). Entomologists tend to be even more specific because, as we have noticed, there are just so many insects; a beetle man is, generically, a coleopterist, but he might be a “carabid man” if the Family Carabidae (ground and tiger beetles) was his favourite family. Since there are more than thirty thousand named species of the family, there is plenty to know about this particular group, and it is not hard to imagine how somebody could spend his or her life getting to understand them. The small town I live in has about ten thousand inhabitants, and I am certainly unable to recognize and name more than a small fraction of them. I find it difficult to imagine being on intimate terms with three thousand people, let alone thirty thousand. When a new species is named and described it has to be distinguished from all the others described earlier; and, not surprisingly, mistakes are occasionally made. I once named a trilobite
Opipeuter,
only to find that the same name had been used a year or two earlier for a South American lizard. It is equally unsurprising that taxonomists tend to be obsessive about what they do. You would have to be to remember the details of so many hairs on so many legs.

Nor are they very well paid. “Looking at butterflies all day…it’s not as if it was real work.” This may partly be a relic from the past. There was a time when to be a museum professional was rather a posh occupation. Private schools were a common background among these elite employees, and probably a private income to match. It was the trade of a gentleman. In those days, perhaps sixty years ago, there was a dress code: suits and ties during the week for the scientific staff. In the Natural History Museum, sports jackets were sanctioned for wearing on Fridays only (by the Director Sir Gavin de Beer) because, after all, this was the day when one went down to the country for the weekend. Later, when one didn’t, the sports jacket became a kind of signature uniform for the museum scientist, complete with leather elbow patches. It indicated an endearing otherworldliness. Too much smartness might betray the wrong priorities, and an inadequate grasp of the carabids. One of my colleagues always wore a marvellously baggy bit of ancient tweed that looked as if it might house a selection of undiscovered species of small organisms. I hope it was curated somewhere upon his retirement, just in case.
