of fly in the village ; but for the most part, the result has been excellent 

 and these clearings must assuredly have played an important part 

 in causing the decided fall in the number of sleeping sickness cases 

 diagnosed in 1914, as compared with the previous year. The sum 

 of £40 was allocated for the purpose of efEecting clearings along the 

 main roads in the S.S. Area. This amount has been partially expended 

 in paying gangs of 50 men at a time, who were employed in clearing 

 the trees and scrub from each side of the Domira Bay-Matumba-Kasu 

 road. Apart from this, the experiment was tried of making every man 

 in certain parts of the Sleeping Sickness Area devote one day in each 

 month to clearing the scrub from the neighbourhood of roads uniting 

 his village with the next. While this rule was in force, much excellent 

 work was done, the Chunzi-Mtalamanja road in particular being cleared 

 for a short distance on either side, along its whole extent.

The Staphyhnid, Paederus fuscipes, Curtis, is found everywhere in 

 the government throughout the year along the banks of rivers and 

 lakes, especially in the delta of Volga. These beetles cause blisters 

 when they are crushed on the skin, and the native fishermen and 

 herdsmen suffer considerably from them. 



Culex pipiens, L., and Anopheles claviger, F., swarm along the 

 lower Volga and along the coasts of Achtoub, attacking man and 

 animals ; there are also swarms of Simuliuni. Tahanus hovinus, L., 

 and T. solstitialis, Meig., both occur, mostly along the coast. Chrysops 

 caecutiens, L., occurs in marshes and on the islands, and attacks men 

 and animals ; Gastrophilus equi, L., {intestinalis, Dg.) and Stomoxys 

 calcitrans, L., are widely distributed, especially in the steppes, causing 

 great suffering to animals. Musca domestica, L., is noticed as occurring 

 in enormous numbers in the villages of the district of Krasno-Jar. 

 Argas persicus is very troublesome on poultry, and caused the death 

 of large numbers of young chickens in spring.

 into Vertebrates. — Proc. Camb. Phil. Soc, Cambridge, xviii, pt. ii,

A series of experiments was performed in order to ascertain whether 

 an insect flagellate might become pathogenic on being introduced into 

 an unassociated vertebrate. Laveran and Franchini have shown 

 that this is the case with nearly associated insects and vertebrates, 

 e.^., rat -fleas and rat or mouse, dog-fleas and dog [see this Review, Ser. 

 B, ii, p. 89], but for the experiments here described, Herpetomonas 

 jaculum, Leger, parasitic in the " water scorpion," Nepa cinerea, was 

 the flagellate used and very young mice served as the vertebrate hosts. 

 The following conclusions are drawn by the authors : — (1) Insect 

 flagellates, e.g., Herpetomonas jaculum, Leger, from Nepa cinerea, and
