the malignant tertian form of malaria. A number of Anophelines 

 were taken in the infected villages, most of them belonging to the 

 species common in Tonkin, including :■ — Anopheles (Mtjzorhynchus) 

 sinensis, A. pseudopictus, A. rossi, A. (Nyssorhynchus) fuliginosus and 

 A. barhirostris.

 Con Stan tin ois Oued Rir'-Oued Souf (avril 1912). [Scientific

Among the mosquito areas studied in the Sahara were Oued Rir, 

 in which are a great number of large and deep pools fed by water from 

 numerous artesian wells and irrigation canals. All the larvae found 

 were Culicines, though the water was always more or less salt. The 

 Anophelines found were all Anopheles {Pyretophorus) chaudoyei, Theo., 

 first discovered and studied in the Touggourt district by Billet and 

 C^haudoye. The measures advised by the authorities consisted in 

 the removal of the population from the old half-ruined villages close 

 to the marshes to a more elevated and therefore drier and better site. 

 At Oued Souf no Anopheles were found. A few Culicine larvae, 

 probably of Theobaldia, were found in tanks used for watering the 

 Government Office garden. Malaria was practically absent.

 pt. xxiii, 30th May 1914, p. 10. [Received 10th October 1914.] 



Cases of sleeping sickness have occurred practically over the whole 

 fly area of the Nyasaland Protectorate. Dr. Sanderson reports that 

 it is difficult to understand why the Dedza district should be free of 

 the disease, marching as it does with the infected Dowa district, the 

 conditions of country, climate and fly being exactly similar. There 

 is apparently some factor not yet recognised and until this is discovered 

 it is not possible to make any statement as to the spread of the disease.

A large amount of work has been done in Germany by the 

 Commission on Warble Fhes regarding minute details of the hfe- history 

 and this paper constitutes report No. 5 of this Commission. One 

 of the questions cor ndered is the time of day when the larvae quit 

 their hosts It has been generally supposed that this takes place 

 early m the morning, rarely in the middle of the day or in the evening. 

 Observations were made on 12 head of warbled cattle during the whole 

 period of infestation, and the results given in detail for each beast 

 show that the maximum dropping of the larvae (70 per cent.) took 

 place between 4.50 a.m. and 7 a.m. ; another 14 per cent, before 

 8 a.m., 8 per cent, before 9 a.m. and the remainder at various other 

 hours. The man in charge went on duty at 4.30 a.m. and on his 

 entry it was observed that all the cattle immediately assumed a stand- 

 ing position and within the next three-quarters of an hour a number
