 maladie du sommeil en Afrique equatoriale frangaise (Pays 

 Bakongo, Bakongui et Loango) , Mai-Juin-Juillet 1912. [Contri- 

 bution to the study of the distribution of Sleeping- vSickness 

 in French Equatorial Africa (Bakongo, Bakongi and 

 Loango), in May, June and July ldl2.]— Bull. Soc. Path. 

 Exot., yp. 34-40, 1 map. 



The author was charged by the Governor-General of French 

 Equatorial xifrica to make a medical report upon the whole of 

 the region which would be traversed by the Southern C'ongo Rail- 

 way which is intended to join Pointe Noire to Brazzaville. 



in Bakongo 30 villages were visited and 1,393 individuals 

 examined; 1-21 per cent, were found to be suffering from trypano- 

 somiasis. The proportion of persons affected varies considerably; 

 in the Bakongi country 1,0G3 were examined and 54 found to be 

 attacked, that is 4-98 per cent. ; in the Kuilu district 592 persons 

 were examined and 21 were found to be attacked, that is 3'5 per 

 cent. In all the districts the distribution of the disease was more 

 or less irregular, and the author points out the danger of the 

 infection of practically healthy villages by the inhabitants of 

 the infected ones, owing" to their both usin^ the same streams as 

 sources of their water-supply, for along the banks of these streams 

 Glossina is by no means uncommon. 



In the village of Kimanga, situated between Buende and Boko 

 Songho on the left bank and 50 metres from the Eiver Inda, an 

 affluent of the Sudiraa, the household of the chief, consisting of 

 18 men, 35 women and 29 children, yielded 6 men, 7 women and 

 3 children attacked by the disease. 



The author remarks that instances of this kind, which are by no 

 means uncommon, and what may be described as cases of family 

 contagion, explain the disappearance of whole villages; similar 

 cases have been observed by other travellers. Eound the village 

 of Kimanga there, is no dense bush, but mosquitos of the 

 genera Mansonioides and Anopheles are plentiful and Glossina 

 palpalis is by no means uncommon. 



Throughout the whole course of their journey the authors met 

 with Glossina palpalis everywhere along the river-banks, though 

 somewhat scarce in the dry season. Among other biting insects 

 thej- met with mosquitos of the genera Anojjheles, Myzomyia, 

 Stegomyia and -Mansonioides ; also Ceratopogon, and almost every- 

 where, especially in dirty houses, the blood-sucking larvae of 

 Auchmeromyia luteola, the chigger flea {S. penetrans), bugs 

 and lice.
