gitic worms. Their laboratories are comfort- 

 able and well equipped. 



One of the most interesting government in- 

 stitutions in London is tbe National Institute 

 for Medical Research. Here are gathered to- 

 gether a number of men who devote their en- 

 tire time to investigation. Among the mem- 

 bers of the staff are Dr. 0. Dobell, the proto- 

 zoologist who has recently published a book on 

 the Amoebfe Living in Man. Working with 

 Dr. DobeU was Dr. M. Koidzumi, of Formosa, 

 who is studying the intestinal protozoa of 

 termites. 



Another institution devoted to research is 

 the Rothampsted Experiment Station at Har- 

 penden near London. The subjects dealt with 

 here include protozoology, entomology and 

 mycology. Dr. D. W. Cutler, who seems to 

 have been the first to successfully cultivate the 

 amoeba of dysentery in artificial media, is now 

 studying the protozoa of tbe soil in relation to 

 soil bacteria. Dr. A. D. Imms is investigating 

 the sensitiveness of insects to various chem- 

 icals. He finds that insects of interest to 

 medicine are much more easily attracted by 

 odoriferous substances than those of agricul- 

 tural importance. 



Several members of the staff of the Natural 

 History Museum at South Kensington are 

 studying animal parasites or their vectors. 

 Dr. H. A. Baylis is building up the depart- 

 ment of helminthology ; Dr. E. E. Austen is 

 continuing his work on tsetse flies and Dr. G. 

 C. Robson is studying the anatomy of snails 

 that serve as intermediate hosts of the trema- 

 todes of schistosomiasis. 



Lack of time forces me to list with only 

 slight comment other institutions and investi- 

 gators who are interested in medical zoology 

 that I was able to visit in London. These in- 

 cluded the protozoologist, Dr. Doris Mackin- 

 non, of King's College; Professor W. M. Bay- 

 liss, the physiologist of University College; 

 Professor A. E. Boycott, of the University 

 College Medical School, who has carried on 

 researches in helminthology in Cornwall ; Pro- 

 fessor W. Bullock, the pathologist at the Lon- 

 don Hospital Medical College; Sir Frederick 

 Andrewes, the pathologist at St. Bartholomew's 



Hospital Medical School; Dr. Arthur Keith, 

 at the Royal College of Surgeons ; Dr. Brough- 

 ton-Alcock and Sir Ronald Ross, at the Min- 

 istry of Pensions; Professor W. J. R. Simp- 

 son, Colonel Clayton Lane and Colonel 

 Stewart, at the Royal Society of Tropical 

 Medicine; Dr. G. A. K. Marshall, of the Im- 

 perial Bureau of Entomology; Dr. Thomson, 

 at the Wellcome Historical Medical Museum; 

 Professor R. T. Hewlett, at the Medical Re- 

 search Club; Professor F. E. Beddard, at the 

 Zoological Society of London, and many 

 others at meetings of societies already men- 

 tioned and at the Royal Society of London 

 and the Royal Society of Medicine. Models 

 of sanitary apparatus and exhibits of life his- 

 tories of mosquitoes, flies and other animals 

 are on display at the Royal Sanitary Insti- 

 tute. 



The Liverpool School of Tropical Medicine 

 was founded in 1898. Here a large amount of 

 investigation has been carried on in the field 

 of medical zoology. The publications of the 

 school include 21 memoirs, many of which 

 embody the results of campaigns carried on 

 in various British colonies; 13 volumes of the 

 Annals of Tropical Medicine and Parasitol- 

 ogy and several text-books on malaria. The 

 school has just become settled in its new 

 building which was completed in 1914 but was 

 taljen over immediately for use as a hospital 

 during the war. The laboratories, library and 

 museum are well designed and equipped and 

 in the hospital nearby is a ward for tropical 

 diseases connected with a student laboratory 

 for clinical and pathological study. The 

 courses in protozoology, helminthology and 

 medical entomology extend over a period of 

 13 weeks. The professors who have charge of 

 the laboratory courses also instruct the stu- 

 dents in the clinical and pathological aspects 

 of parasitic diseases; the school differs in this 

 respect from the London School of Tropical 

 Medicine. At the time of my visit Professor 

 J. W. W. Stephens was director and taught 

 protozoology, with the assistance of Dr. Black- 

 lock; Professor Newsted, Mr. H. F. Carter and 

 Miss Evans were the entomologists, and Pro-
