In 1840 he published "Demonstrations of Anatomy: being a Guide to the Knowledge of the Human Body by Dissections", his name becoming a household word among medical students, and his work becoming the standard textbook in England and the United States.
[4] During Ellis' tenure the University College London was regarded as the pre-eminent centre for the study of anatomy, its spacious and well-lit dissecting room approved of by both staff and students.
The College was fortunate in acquiring and retaining the services of an anatomist of Ellis' stature - his culture, zeal, and energy were legendary - receiving only a moderate salary and with no prospect of career improvement.
On his retirement Ellis came into a small fortune left him by a relative, built himself a house at Minsterworth, 'Severn Bank', and lived there quietly with his younger sister, devoting himself to gardening and apple-growing.
[6] Ellis wrote the greater part of the description of the nerves in Sharpey's edition of Jones Quain's "Elements of Anatomy", 6th ed., 1856, and contributed several papers on scientific subjects to the London Medical Gazette.
