This paper continues one by Beck and Week [see this Review, Ser. B, 

 i, p. 67] on an outbreak of trypanosomiasis on the Rovuma river, where 

 72 cases of sleeping sickness have been discovered. Investigations 

 up to date show Glossina inorsitans alone to be the carrier and in the 

 districts affected, 8 to 10 per cent, of this fly are infected with trypano- 

 somes, the identity of which has not yet been established. Most 

 probably they are identical with the T. rhodesiense described by English 

 doctors, but the posterior nucleur characteristic of T. rhodesiense only 

 occurs exceptionally in fresh blood preparations. Comparative 

 research leads to the conclusion that this trypanosome is not identical 

 with that found in spontaneously infected animals (mules and cattle) 

 nor with the one observed in a number of other animals (waterbuck 

 and eland).

 mettre le Trypanosom'i cruzi. [Reduviids of North America 

 capable of transmitting Trypanosoma cruzi.] — Bull. Soc. Path. 

 Exot., Paris, vii, no. 2, 11th Feb. 1914, pp. 132-133. 



Trypanosoma cruzi has been found in Triatoma (Conorhinus) megistus 

 by C. Chagas and equally abundantly in T. infestans and T. sordidus. 

 Whilst investigating a virus from Bahia, the author demonstrated that 

 various bed-bugs [Cimex lectularius, C. hemiptera {rotundatus) and 

 C. boueti) could be infected with T. cruzi, as well as a tick, Ornithdorus 

 moubata. With Gonzalez-Lugo the author proved Rhodnius prolixus 

 to be a carrier of T. cruzi, and this Hemipteron shows a long infection. 

 Rhipicephcdus sanguineus has been shown by Neiva to be an inter- 

 mediate host. The Triatoma used in these experiments were from 

 the Dallas Laboratory, Texas.

The preceding year's investigations on the distribution and abund-

 neighbourhood and the east portion of Austrian Silesia, were visited,
