Synopses & Reviews
William Charles Wells (1757-1817) was one of the foremost, and forgotten, American scientists of the eighteenth century. He was trained in medicine and conducted experimental studies in vision and vertigo, he proposed a theory of how dew forms, and he speculated on the mechanism of natural selection. Despite the originality of his enquiries in all these areas, Wells' contributions to scientific discovery have been either neglected or ignored. Although he was born in America, Wells was educated in Scotland and practiced medicine for most of his adult life in London. His practice did not thrive, and he had ample time to conduct his experimental enquiries on a variety of natural phenomena. He was acquainted with the leading medical men of the day, and was admired by them. The emergence of experimental studies of vision can be traced to the adoption of Newtonian methods of observation and experiment, and in their application to space perception by Wells (1792). His initial researches were concerned principally with binocular vision, but he also conducted experimental studies of accommodation, acuity, eye movements, and vertigo. With regard to the last, he entered into a debate with Erasmus Darwin concerning the involvement of eye movements in vertigo. Indeed, Wells should be acknowledged as laying the foundations for modern studies of vestibular function as well as eye movements. The book reprints his Essay on single vision with two eyes (1792) and his own Memoir of his life (1818). Wells also outlined a theory of natural selection before Charles Darwin and provided an account of the formation of dew. His essay on natural selection is reprinted as an Appendix to the book. Wells' experiments and observations on natural phenomena will surprise students of science because of their modernity.
Review
"Wade's extensive knowledge [...] allows him to do a skillful job relating Well's contributions to earlier and later developments[...] The volume will interest serious scholars of visual perception and those interested in the history of this science[...] Highly recommended." (Choice, 41:4 (December 2003)

Synopsis
My fIrst encounter with the name of William Charles Wells, over twenty years ago, was an oblique reference to his Essay upon single vision that Wheatstone (1838) made in a classical article on binocular vision. The reference was enigmatic because it stated that few had paid attention to Wells' theory of visual direction, while doing little to infonn the reader of its novelty. I was fortunate in having the excellent facility of the Rare Books and Manuscripts Department of the Library at the University of St. Andrews near at hand, so that I could cousult a copy of Wells' monograph. However, I was not aware of the full import of its contents until Hiroshi Ono visited Dundee from York University, Ontario, in 1980. Hiroshi had previously fonnalised the principles of binocular visual direction that Hering (1879) had proposed. He returned one day from St. Andrews, having read Wells' Essay upon single vision, amazed to have found that Wells had perfonned similar experiments and reached similar conclusions to Hering. Hiroshi Ono has done much to bring Wells' work on binocular single vision to the notice of visual scientists, although its reception has not been without opposition. As I read more of Wells' work on vision I became aware of its breadth as well as its depth. In addition to his essay on binocular single vision, he wrote about and conducted experiments on accommodation, visual acuity, visual persistence, and vertigo.
