The author, continuing the investigations of Dr. Lamoureux in 

 connection with indigenous malaria in the Lake Presba region [see this 

 Review, Ser. B, vi, p. 12], records examinations of 14 children in this 

 area between 1st and 17th September 1917, none of which had 

 received quinine treatment. The results agree with those previously 

 made and confirm the existence in the region west of Lake Presba, 

 during the spring and summer season, of indigenous malaria due only 

 to Plasmodium vivax.

Twenty-five cases of indigenous malaria have been studied in this 

 region ; eight of these being exclusively due to the parasite of 

 quartan malaria {Plasmodium, malariae) and five others to parasites 

 of the benign tertian form (P. vivax). One case only of malaria, in 

 a hospital where soldiers from Salonika were under treatment, showed 

 the malign tertian form. These cases of indigenous malaria respond 

 readily to quinine treatment ; in fact such a diminution of the disease 

 was obtained in September and October that the population is 

 continuing the treatment, being persuaded that they will by this means 

 be eventually freed from the fever.

The authors have previously, in 1911, made experiments to determine 

 whether the forms assumed by the trypanosomes of mammals in the 

 digestive tract of Glossina can adapt themselves to that of non-blood- 

 sucking insects that can harbour forms alhed to Crithidia. Having 

 found Crithidial forms in the digestive tract of Gerris fossarufn, the 

 latter were regularly fed on Glossina morsitans taken in the open and 

 largely infected with Trypanosoma co)igolense, T. pecaudi and 

 T. cazalboui. Iiifection did not result, the trypanosomes of G. morsitans 

 evidently not adapting themselves to the intestine of Gerris fossarmn. 

 ■ By similar experiments it was proved that trypanosomes that 

 abound in Pycnosoma, Sarcophaga and Glossina cannot develop in the 

 intestine of Asilids [see this Review, Ser. B, i, p. 140] ; trypanosomes 

 of Pycnosoma do not adapt themselves to the intestine of mosquitos 

 of the genus Stegomyia, nor to bugs such as Cimex hemipfera 

 {rotundatus) ; those of Glossina palpalis do not become adapted to 

 the intestine of S. fasciata or of C. hemipfera. These results indicate
