In the case of domestic animals, all those on plantations situated 

 in the zones formerly infested by Glossina palpalis were examined 

 in November 1913, and out of 197, trypanosomes were found in five; 

 three of these were oxen recently imported from South Angola, one an 

 ox that had long been in the island, and one a mule from Lisbon. 

 The percentage of animals attacked was therefore only 2"5, whereas 

 a Hke examination by the same process in May 1912, shewed 19 per 

 cent, of infection. 



Dr. da Costa concludes by expressing the confident hope that if 

 the sanitary measures proposed are efficiently carried out, sleeping 

 sickness in Principe may become a thing of the past. 



Tables are given at the end of the report shewing the number of 

 labourers, the number of old cases of sleeping sickness, the number 

 of persons examined, the results of the microscopic examination, 

 the country of origin of new cases, and their period of residence in the 

 island. Similar details are also given with regard to domestic animals.

 Insekten im Bezirk Bukoba. [Coffee cultivation, coffee pests and

This paper, which deals principally with the cultivation of coffee 

 In Bukoba, concludes with notes on the insects harmful to man and 

 animals in that district. Tsetse-fly exists in few localities, and the 

 author took Glossina morsitcms on two occasions. G. -palpalis 

 appears to be dying out, and sleeping sickness is correspondmgly 

 decreasing. A more important pest is Ornithodorus mouhata, Murray, 

 which carries recurrent fever ; the natives of the district appear to 

 be immune, but strangers are almost invariably attacked. Owing 

 to the habits of the ticks it is difficult to escape their bites, though 

 a certain amount of protection is obtained if the sites of old camps 

 be avoided ; mosquito nets afford protection, and as a further means 

 of keeping off the ticks, the supports of the camp bed may be bound 

 round with material moistened with petroleum. 0. savignyi, common 

 in Uganda, is not known in Bukoba. Mosquitos appear in very large 

 numbers after the rains. Anopheles spp. are widespread. Tenebrionid 

 beetles appeared to be common in the native huts, living in the 

 straw covering the floors ; the natives affirm that these beetles bite. 

 Rhipicephalus capensis was taken on cattle and donkeys.

Human trypanosomiasis, discovered by Chagas for the first time 

 in the State of Minas-Geraes, has been found to exist also in Goyaz, 

 Bahia, and in the Argentine. Lafont discovered trypanosomes in the 

 blood of animals in the island of Mauritius ; this trypanosome 

 resembled very closely the parasite causing the disease in the above- 

 mentioned States, namely Trypanosoma cruzi. The authors have
