wliether tlie artificial contamination of ponds and marshes in malarial 

 countries will prove an efficacious means of combating these mosquitos, 

 and consequently malaria. 



Calveet (P. P.). Insects and Human Mortality in War. — Old Penn, 

 Philadelphia, xvi, no. 12, 21st December 1917, pp. 297-302. 



This paper is the report of a lecture delivered by the author in 

 Philadelphia. 



The various diseases that have been responsible for a high percentage 

 of mortality in the present and in previous wars are reviewed, almost 

 all of these being now known to be insect-borne. The relation of the 

 louse, Pediculus humanus (vestimenti), to typhus are discussed in 

 detail, the history of the investigations into this relation being given, 

 and the importance of keeping typhus patients and these insects 

 apart, which has so far been successfully accomplished during the 

 present campaign on the western front, is insisted upon. The French 

 anti-malarial campaign of 1917 in the Balkan Army is described. 

 The dangers arising from the prevalence of house-flies and mosquitos 

 in the neighbourhood of training- camps are discussed, a promising 

 feature being the marked improvement that has been observed in those 

 camps where fly and mosquito control has been thoroughly and 

 practically carried out, the insect problem in many camps being 

 considered as solved. 



The author emphasises the immense importance of entomological 

 science in discriminating the kinds of insects, in elucidating their 

 physiology and life-history, without which their vulnerable points 

 cannot be known, and in discovering their relations to the rest of the 

 world and the health of its plant and animal inhabitants ; in all of 

 these fields much yet remains to be learned. Experience demonstrates 

 that all insect problems affecting the health of the army and of the 

 civilian population supporting it should be investigated by men trained 

 in entomological work.

 [Received 2nd February 1918.] 



This brief notice calls the attention of sheep owners to the necessity 

 of using poisonous powder dips in compliance with the requirements of 

 the Stock Diseases Act, a case having arisen in which a flock treated 

 with a non-poisonous carbolic dip had shown signs of infestation by 

 ticks and lice three weeks later.

This paper describes detailed observations of the life-history and 

 habits of Cicindela campestris, the larvae of which burrow in sand, 

 peat, or in the borders of sandy roads. Their favourite food appears 

 to be blow- flies, which may often be seen projecting from a larval 

 burrow.
