 found in about half the cases examined, though an enlarged spleen waa 

 rarely found.

 Traitement des Palud6ens en Mac6doine. [Practical Considera- 

 tions of the Prophylaxis and Treatment of Malarial Subjects in 

 Macedonia.]— £wH. Soc. Path. ExoL, Paris, x, no. 10, 12th 

 December 1917, pp. 923-932. 



The author records in this paper the results he has obtained in the 

 treatment of malaria through two summer and autumn seasons with 

 the Balkan army. His experiences have led him to the conclusion that 

 malaria among the army in Salonika should be treated by the standard 

 methods, the application of which should be supervised. He considers, 

 that quinine is the only medicine required, the best method of 

 administration being by the mouth ; this treatment should be 

 prolonged and thorough, and is quite compatible with regimental 

 service in war time. Anti-malarial prophylaxis is quite possible and 

 can be made in a large measure a sufficient preventive of the disease, 

 but can only be efficiently carried out by regimental doctors when 

 acting under military authority and when themselves convinced of the 

 efficacy of their methods.

This paper gives an account of Gamhisia affinis, a small fish that 

 hves almost entirely on the larvae of harmful insects. In waters where 

 mosquito-eggs are laid the larvae constitute the principal diet of 

 G. affinis, being devoured in enormous quantities. This fish is. 

 considered superior to any other species as a mosquito-destroyer.

Investigations on the value of potassium cyanide as a larvicide have 

 showTi that when used at the strength recommended by Eoss and Edie 

 (Ann. Trop. Med. & Parasitology, v, p. 385, 1911) it is very destructive 

 to the egg and young pupal stages of mosquitos, but is not so harmful 

 to the pupae. Owing to the number of grades of potassium cyanide on 

 the market, further experiments are necessary before definite results 

 can be obtained. 



Experiments to test the effectiveness of a cresyl fumigation apparatus 

 against mosquitos are not yet completed. Investigations into the 

 relative mosquito density of a given area of Townsville are being 

 carried out.
