Chagas, C. Uber eine neue Trypanosomiasis des Menschen. Memoriasis do Insti- 

 tuto Oswaldo Cruz., Rio Janerio, Vol. 1, 1909. A disease similar to sleeping sick- 

 ness thought to be transmitted by Reduviid bugs, especially Conorhinus megistus 

 Brum. A small monkey is thought to be the reservoir of the virus.

Minchin, E. A. and Thomas, D. Transmission of Trypanosoma lewisi by rat 

 fleas. Proc. Roy. Soc. series B, 82 (1910), p. 273-285. Show that C. fasciatus 

 can transmit T. lewisi from infected to non-infected rats. Transmission not direct^ 

 but parasite must undergo a development of six or seven days in the flea. 



Swellengrebel, N. H. and Strickland, C. The development of Trypanosoma 

 lewisi outside of the vertebrate. Parasit., September, 1910. Experiments show 

 that it develops normally in Ceratopsyllus fasciatus; irregularly or incompletely 

 in the rat louse or bedbug, and not at all in the tick (0. moubata). 



Strickland, C. and Swellengrebel, N. H. Notes on Trypanosoma lewisi and its 

 relation to certain Arthropoda. Parasit., December, 1910. Fleas, lice, bugs, ticks 

 and mites were experimented with but the parasite was transmitted only by the flea.

The Sleeping Sickness Commission of the Royal Society, composed of David A. 

 Bruce, A. E. Hamerton, H. R. Bateman, and F. P. Mackie, published the following 

 papers in the Proc. of the Royal Soc. series B, vol. 82, 1910: 



Amakebe: A disease of calves in Uganda, p. 256-272. This disease of calves cor- 

 responds to East Coast Fever of adult cattle and is carried in the same way by 

 Rhipicephalus appcndiculatus (brown tick), R. evertsi (red-legged tick), and R. 

 simus, all common in Uganda. 



The development of trypanosomes in tsetse flies, p. 368-388. Show that T". 

 gambiense and other species multiply in the gut of Glossina palpalis and the flies 

 become infective, on an average, thirty-four days after their first feed, and may 

 remain infective for seventy-five days. 



Trypanosome diseases of domestic animals in Uganda. 1. Trypanosoma pecorum, 

 p. 468-479. This parasite causes an important disease of cattle and is probably 

 carried by a Tabanus and not by Stomoxys. 



Experiments to ascertain if cattle may act as a reservoir of the virus of Sleeping 

 Sickness, p. 480-484. Experiments proved that they may do so. Healthy animals 

 may be infected from them by means of Glossina palpalis. Cattle in the fly area 

 naturally harbor T. gambiense and it is therefore possible that cattle and antelope 

 may keep up the infectivity of the fly for an indefinite period. Up to the present 

 time there is no proof that this actually takes place in nature. 



"Muhinyo," a disease of natives in Uganda, p. 485-490. This is Malta Fever 

 and is conveyed from the goat to man by the drinking of the goat's milk. 



The natural food of Glossina palpalis, p. 490-497. In the first series 27 per cent 

 of the flies had fed on blood, the majority of which was of mammalian origin. In 

 the second series nearly 60 per cent contained the remains of a blood meal mostly 

 from birds or reptiles. 



Mechanical transmission of Sleeping Sickness by the tsetse fly, p. 498-501. 

 Mechanical transmission can take place if the transference is instantaneous — that 

 is by interrupted feeding — but not if an interval of time comes between the
