Literate Lifetime
"Today a reader, tomorrow a leader." -- W. Fusselman
Bates, Henry Walter, 1825-1892We have 2 books for this author.Henry Walter Bates FRS, FLS, FGS (February 8, 1825 – February 16, 1892) was an English naturalist and explorer most famous for his expedition to the Amazon with Alfred Russel Wallace in 1848. Wallace returned in 1852, but lost his collection in a shipwreck. When Bates arrived home seven years later (in 1859) he had sent back over 14,000 specimens (mostly insects) of which 8,000 were new to science. Bates was born in Leicester and, like Wallace, T.H. Huxley and some other British scientists of the time, he had no formal education in science, and left school at 12. He came from a literate middle-class family and taught himself mainly by reading (like Wallace, Huxley and Herbert Spencer, he was an auto-didact). At 13 he became apprenticed to a hosier. He joined the Mechanics' Institute (which had a library), studied in his spare time, and collected insects in Charnwood Forest. In 1843 he had a short paper on beetles published in the Zoologist (Bates 1843). Bates became friends with Wallace when the latter took a teaching post in the Leicester Collegiate School. Wallace was also a keen entomologist, and he had read the same kind of books as Bates had, and as Darwin, Huxley and no doubt many others had. Malthus on population, Hutton and Lyell on geology, Darwin's Voyage of the Beagle, and above all, the anonymous Vestiges of the Natural History of Creation, which put evolution into everyday discussion amongst literate folk. They also read William H. Edwards on his Amazon expedition (Edwards 1847), and this started them thinking that a visit the region would be exciting, and might launch their careers.(Moon 1976) The great adventureIn 1847 Wallace and Bates discussed the idea of an expedition to the Amazons, the plan being to defray expenses by sending specimens back to London where an agent would sell them for a commission, and for the travellors to "gather facts towards solving the problem of the origin of species", as Wallace put it in a letter to Bates. The two friends, who were both by now experienced amateur entomologists, met in London to prepare themselves by viewing South American plants and animals at the main collections (Bates 1863 Preface). Also they collected 'wants lists' of the desires of museums and collectors. Letters survive in the Kew library of letters from the pair asking what plants the Director (then William Jackson Hooker) would like them to find. Never has the old adage of a prepared mind been more apposite. Bates and Wallace sailed from Liverpool in April 1848, arriving in Pará (now Belém) at the end of May. For the first year they settled in a villa near the city, collecting birds and insects. After that they agreed to collect independently, Bates travelling to Cametá on the Tocantins River. He then moved up the Amazon, to Óbidos, Manaus and finally Tefé, which was his headquarters for four and a half years. His health eventually deteriorated and he returned to England, sending his collection by three different ships to avoid the same fate as Wallace. He spent the next three year writing his account of the trip, The Naturalist on the River Amazons (Bates 1863), widely regarded as one of the finest reports of natural history travels. [more to come] Home at lastIn 1861 he married Sarah Ann Mason (Woodcock 1969). From 1864 onwards, he worked as Assistant Secretary of the Royal Geographical Society (effectively, he was the Secretary, since the senior post was occupied by a noble figurehead). He sold his personal Lepidoptera collection to Godman and Salvin and began to work mostly on beetles (cerambycids, carabids, and cicindelids). In 1881 he was elected a fellow of the Royal Society. He died of bronchitis in 1892. A large part of his collections are in the Natural History Museum. Consult The Field, London, February 20, 1892. Specimens he collected went to the Natural History Museum [then called the BM(NH)] and to private collectors; yet Bates still retained a huge reference collection and was often consulted on difficult identifications. This and the disposal of the collection after his death are mentioned in Edward Clodd (1916) Memories. Henry Bates was one of a group of outstanding naturalist-explorers who were supporters of the theory of evolution by natural selection (Charles Darwin and Alfred Russel Wallace 1858). Other members of this group included J.D. Hooker, Fritz Müller, Richard Spruce and Thomas Henry Huxley. Bates' work on Amazonian butterflies led him to develop the theory of mimicry which now bears his name: Batesian mimicry. This is the mimicry by a palatable species of an unpalatable species. A common example seen in many gardens is the hover-fly which, though bearing no sting, mimics the warning colouration of wasps. Such mimicry does not need to be perfect to improve the survival of the palatable species (Winkler 1968). Bates, Wallace and Müller believed that Batesian and Müllerian mimicry provided evidence for the action of natural selection, a view which is now standard amongst biologists (Moon 1976). Field and experimental work on these ideas continues to this day; the topic connects strongly to speciation, genetics and development (Mallet 2001). [more to come] References
