organisms showed distinct terminal swellings. They observed also in a 

 few cases in the lymph spaces or within cells black or yellow corpuscles, 

 which may be resting stages of Spirochastae, but this is doubtful. 



Trypanosomata of Gambian Fever and Sleeping Sickness.* — H. 

 Wolferstan Thomas finds that the parasites of these diseases are identical 

 with T. gambiense. This conclusion is come to after over 1000 ex- 

 periments, nearly 600 of which were on rats. The resulting symptoms 

 after infection are similar, and the parasites in the normal condition 

 cannot be distinguished from each other. These results are directly 

 opposed to the conclusions previously published by H. G. Plimmer. 



Suspected New Human Trypanosome.f — Kudicke found Trypano- 

 somes in the blood of a Oercopithecus into which had been injected blood 

 from a fever patient from the south coast of Victoria Nyanza. The 

 parasites appeared after seventeen days. Inoculation of other Cercopitheci 

 gave negative results. The trypanosome resembles T. theileri which, 

 according to Theiler, occurs only in cattle. Whether, this is a new 

 species is, however, at present undecided. 



Trypanosome of Dourine Introduced into Ruminants and Monkeys.J 

 F. Mesnil and J. Rouget have shown that the Trypanosome of Dourine, 

 in spite of previous statements, may be introduced into Ruminants and 

 monkeys. There is not in this respect any contrast between dourine and 

 other forms of Trypanosomyasis in Algeria. 



Flagellates from the Intestine of Diptera.§ — A. Lingard and 

 E. Jennings give descriptions of flagellate and other forms found in 

 Musca ilomestica, Siomoxys calcitrans, and a species of Oulex, grouping 

 them according to locality, thus : — (1) Those from the plains of the 

 United Provinces, India : (2) from the Himalayas at an elevation of 

 7500 ft. above sea level (Muktesar). In addition there is a detailed 

 account of numerous flagellate organisms discovered in the body cavity 

 of a fly (species undetermined), together with a record of the results 

 obtained after feeding the common house-fly on mouldy wheat. These 

 last experiments yielded a number of parasites, the majority of which 

 were traceable to the wheat. The authors make the suggestion, based in 

 part upon their results, that rice may harbour Protozoa or other 

 organisms, and ofl'er hints as to the investigation of beri-beri as possibly 

 communicated by this cereal, particularly if the rice is of inferior quality 

 or has been lying in bulk prior to or during the rainy season. 



Culture of Coccidium hominis.|l — B. Galli-Valerio finds that the 

 spores of Coccidium hominis develop upon the agar of Nissle and 

 Wagener. In two days they show segmentation, and in seven or eight 

 days the majority of the coccidia show merozoites already formed. By 

 adding now and again a little water the culture may be kept for months.
