The author says that the German colonists have from the outset 

 done what they could to improve the sanitary conditions of their new 

 country, and in this short paper he deals with what has been done 

 especially against endemic malaria. He says that, even in the good 

 season, the climate is particularly exhausting and depressing, and that 

 though during the construction of the railway from Dar-es-Salaam 

 to Tabora a large number of natives fell victims to malaria, on the 

 other hand the drainage and other works have effected the greatest 

 improvement. The use of petroleum, he was told during his visit, 

 had not yielded very satisfactory results, and the colonists are now 

 busy raising fish as destroyers of mosquito larvae. Attention, however, 

 is being more especially paid to individual prophylaxis. Quinine 

 for this purpose is not in great favour with the colonists and officials, 

 but on the other hand metalUc gauze is used in all buildings and some 

 of them, especially the fine Colonial Hospital, are so thoroughly 

 protected in this way that the author says that it must be practically 

 impossible for a single mosquito to enter. In the private houses it 

 is common to find a portion of the verandah elaborately protected 

 with wire gauze in such a way that the occupants may sit there in the 

 evening and drink their beer in peace. Every bed is provided with 

 a mosquito curtain. 



The authorities realise that the natives are the principal source from 

 which the mosquitos, against which they seek to protect themselves, 

 derive the malarial poison, and that so long as they are surrounded 

 by infective natives, so long will they, if bitten, be liable to malaria. 

 In order to reduce this to a minimum the native quarters are regularly 

 investigated every week and samples of blood taken, and in those 

 cases in which the organism is found, the individual is at once subjected 

 to an intensive quinine treatment and everything is done to prevent 

 the mingling of infective natives with the uninfected. The regular 

 inspection is most rigorously carried out. The caravans present the 

 greatest difficulty because the natives composing them penetrate into 

 the most gravely infected areas. These caravans are inspected by 

 medical police throughout the whole route. 



The result of these vigorous and careful measures has been to reduce 

 the mortality amongst the natives very considerably and the cases of 

 fever amongst Europeans have fallen from 40 per cent, to 10 or 15 

 per cent. The pernicious type has become rare, and the author says 

 that though the results are perhaps not all that might have been hoped 

 for, the energy and persistence of the colonists in combating the disease 

 are worthy of all admiration.

The authors point out that Laveran and Mesnil have differentiated 

 the trypanosomiasis of horses in Annam from Indian surra and have 

 given the specific organism the name of Trypanosoma annamcnse. 

 The disease appears every year at various times at Hue (Annam4-
