 (Ibenga Motaba) en 1914. — />////. Soc. Path. Exot., Pans, xiii, 

 no. 10, 8th December 1920, pp. 817-829. 



The results arc recorded of an investigation into the occurrence 

 of sleeping sickness in the territory of Ibenga-INlotaba, in the Ubangi 

 district of French Equatorial Africa in 1914. The situation in various 

 locahties of this district is described. The whole review occupied 

 three months, and in the course of the campaign 20,000 natives were 

 visited, 15.2 per cent, being found infected. 



Clapier (P.). Enquete demographique et Etat actuel de la Trypano- 

 somiase au Pays Bangala (Af. Eq. Fr.). — Bull. Soc. Path. Exot., 

 Paris, xiii, no. 10, 8th December 1920. pp. 830-847. 



The Bangala tribes on the French banks of the Ubangi and Congo 

 Rivers are rapidly dying out. Glossma palpalis is abundant all the 

 year round ; Bangala is considered to be one of the oldest foci of 

 sleeping sickness, and deaths from the disease are very numerous 

 at the present day. While this is not the sole cause of the decreasing 

 population, a rapidly declining birthrate, the use of drugs, and the 

 employment of slaves for all physical work being contributory causes, 

 trypanosomiasis undoubtedly takes a large toll of the population ; 

 in a given time there are fewer births than cases of infant mortality 

 from the disease. It is estimated that in a quarter of a century the 

 race will have ceased to exist. While prophylaxis will protect the 

 individual, it cannot save the race in this district, and the situation is 

 a good example of the urgent necessity for perseverance in prophylactic 

 measures in any region that is threatened with a similar fate. 



RoDHAiN (J.). Observations diverses concernant Onchocerca volvulus. 

 —Bull. Soc. Path. Exot., Pans, xiii, no. 10, 8th December 1920, 

 pp. 848-858. 



From personal observation in the Belgian Congo the author describes 

 the general distribution of human onchocerciasis in the Belgian part 

 of the Congo basin, the local reactionary phenomena exhibited by 

 filarial nodules, the locaUsation of fibromatic nodules and their histology, 

 and finally a case of filarial tumour in a European, caused b\^ Onchocerca 

 volvulus. Microfilaria perstans was also found in the blood of this 

 patient. The case was that of a Belgian who had for many years 

 resided during long periods in Africa, and who had carried the cyst 

 for seven years without any local discomfort. 



Bektarelli (E.). Tentative di Trasmissione della Malaria al Macaco. 



[x\n Attempt to Transmit Malaria to a Macacus.] — Ann. d'I,s;iene, 

 Rome, XXX, no. 11, November 1920, pp. 689-690. [Received 

 21st January 1921.] 



With reference to Mesnil and Roubaud's experiments in inoculating 

 chimpanzees with Plasmodium vivax [R. A.E., B, viii, 217], an account 

 is given of a similar attempt with Macacus cynomolgus, the blood 

 used being taken from a case of typical tertian malaria with gametes. 

 Some of the parasites were near sporulation, and there were a few 

 gametic forms also. The experiment proved negative.
