These conclusions are extremely favourable to the method discussed 

 [see this Review, Ser. B, vi, p. 42], which is said to be efficacious, 

 inoffensive, rapid, prophylactic, hygienic and cheap.

In the course of his Presidential address to the American Association 

 of Economic Entomologists, the author, illustrating the importance 

 of medical entomology, pointed out that in addition to the sickness 

 and death occasioned by insect-borne diseases, the American nation 

 suffers an annual economic loss of some £71,600,000 from the same 

 cause. Under War conditions, circumstances conducive to such loss 

 are magnified many times over, while man-power in civil life is also 

 more than ever in need of being conserved. A very high estimate 

 is therefore placed on the value of knowledge concerning the insects 

 that transmit diseases as a factor in winning the War, and this is 

 applicable not only in the army but also in civil life.

An unprecedented situation has arisen owing to the War, all nation- 

 alities of the human race being gathered together on the battlefields 

 of Europe and bringing with them their blood parasites and infections, 

 creating conditions for the dissemination of disease that are un- 

 paralleled in the history of the world. It is feared that the American 

 troops may prove particularly susceptible, owing to the fact that their 

 higher standards of living have in a measure reduced resistance to 

 disease, though this may be offset to some extent by preventive 

 inoculations. The total numbers of deaths from disease in the present 

 and in previous wars are given and are contrasted with the number 

 of deaths from wounds. Almost all of these diseases are insect-borne, 

 and they account for far greater mortality than wounds. Striking 

 instances are given of immense reductions in the number of cases of 

 disease after the application of preventive measures. The control 

 of certain diseases is undoubtedly determined by the solution of the 

 insect problem ; this is notably true of typhus and lice, bubonic 

 plague and fleas, and yellow fever or malaria and mosquitos. The 

 relation between insects and disease is less evident, though very real, 

 in the case of flies and such diseases as cholera, typhoid, dysentery 

 and probably tuberculosis. Insect control is considered only second 

 in importance to the equipment and provisioning of the army and the 

 care of the sick and wounded. The probabilities are that, as the War
