xxiv Biographical Sketch of 



expert manipulator. During his stay at the Grerman Hospital he found time to attend 

 some of the classes at University College, London, and there he was so successful in his 

 studies, that he obtained the "Fellowes" silver medal for clinical medicine in 1866. 

 Subsequently he went to Aberdeen, where he proceeded to the M.B. and CM. degrees 

 of that university, and graduated with honours in 1867. 



Eventually, he became a candidate for the Army Medical Department of Her 

 Majesty's Service ; and, at the London examination in February 1868, he passed into 

 the Army Medical School at Netley first in the order of merit ; and at the end of the four 

 months' course of study, he again passed out at the top of the list. In both examin- 

 ations (in London and at Netley) he gained exceptionally high marks in all the subjects, 

 and especially in pathology, medicine, and hygiene. His commission, as Assistant- 

 Surgeon in Her Majesty's Army, is dated March 31st, 1868 ; Surgeon, March 1st, 

 1873; and Surgeon-Major, March 31st, 1880. 



At the time when Lewis entered Netley, the attention of the scientific world was 

 occupied with the so-called fungoid theories, regarding the causation of cholera, pro- 

 pounded by Professors Hallier and De Bary. At the suggestion of the Professors of 

 the Army Medical School, the Secretaries of State for War and for India sanctioned 

 the sending of the two gentlemen who secured the highest marks at the Netley ex- 

 amination, in the British and Indian Medical Services respectively, to Grermany, to 

 study for a time under the expounders of these fungoid theories, and thence to India, 

 for the purpose of fully and completely investigating and reporting upon them and the 

 pathology of cholera. 



Drs. T. E. Lewis and D. D. Cunningham were the two gentlemen selected for 

 this important inquiry, and instructions were drawn up by the Senate of the Army 

 Medical School for their guidance. 



After visiting Professors Hallier and De Bary, they proceeded to Munich, where 

 they were most kindly received by Professor Max von Pettenkofer, with whom Dr. Lewis 

 maintained a life-long friendship and correspondence. Having spent about three months 

 in Germany with these eminent teachers, Drs. Lewis and Cunningham proceeded to 

 India, and reached Calcutta in January 1869, where soon afterwards they were attached 

 for special duty to the Sanitary Commissioner with the Grovernment of India, and from 

 which time until January 1880, Lewis was entirely occupied in cholera and kindred 

 inquiries, usually in conjunction with Cunningham, until, in 1879, the latter was 

 appointed Professor of Physiology in the University of Calcutta. 



Having mastered the native language, they were able to pursue their inquiries 

 in remote Indian towns and villages, as well as in the more important cities ; and 

 excursions, of longer or shorter duration, were constantly being made wherever cholera 

 was to be found, often in the company of Dr. J. M. Cuningham, then Sanitary 

 Commissioner with the Government of India. 



Their first report was published as an appendix to the Sixth Annual Repm^t of the 

 Sanitary Commissioner with the Government of India, 1870, ^' On Microscopic Objects in
