Thomas Rymer Jones, an English anatomist, born about 1810. He became a member of the royal college of surgeons in 1833, but on account of a defect in his hearing has never practised. Subsequently he was appointed professor of comparative anatomy in King's college, London. His first work, " A General Outline of the Animal Kingdom " (8vo, 1841), written to supply a want in English scientific literature, established his reputation as a comparative anatomist and physiologist, and is still regarded as one of the best works of its kind in any language. About this time he was appointed Fullerian professor of physiology in the royal institution, and subsequently he became examiner in comparative anatomy and physiology in the London university. In 1845 and 1852 were published the first two volumes of his Fullerian lectures, under the title of " Lectures on the Natural History of Animals," the work being still incomplete. His other works are: " General Outline of the Organization of the Animal Kingdom, and Manual of Comparative Anatomy" (1855); "The Aquarian Naturalist" (London 1858); and "The Animal Creation" (1865). He also contributed to the " Cyclopaedia of Anatomy and Physiology."
