 pp. 207-210. 



The establishment of military construction camps has been practically 

 unattended by sickness owing to the enforcement of sanitary measures, 

 especially those directed against flies, the chief of which include the 

 daily cleansing of the camp by the removal of garbage in fly-proof 

 covered containers for pig-feeding; the daily removal of manure, 

 which is at once spread on the fields ; the daily purification of fly-proof 

 latrines or outhouses ; and the constant examination of the water supply.

King [see this Review, Ser. B, v, p. 73] has investigated the validity 

 of the older assumption that the development of malaria parasites in 

 Anopheles is arrested at a temperature of about 60° F. and that the 

 parasites themselves are destroyed at lower temperatures. A series of 

 experiments with Plasmodium vivax (the parasite of tertian malaria) 

 in Anopheles quadrimaculatus showed that it can survive exposure 

 to a temperature of 30° F. for 2 days, 31° F. for 4 days, and a mean 

 temperature of 46° F. for 17 days. In a smaller series of experiments 

 with Plasmodium falciparum (the aestivo-autumnal parasite) in th& 

 same species of mosquito, the sporonts showed a 24-hour resistance to 

 temperatures as low as 35° F.

The subject matter of the first part of this paper has already been 

 noticed [see this Review, Ser. B, i, p. 139]. Measures for eradicating the 

 ticks must be directed towards destroying them on their hosts by 

 pouring an insecticidal liquid into the ears, the best preparation being 

 two parts each of Stockholm tar and oil to one part of turpentine ; from
