PiETTRE (M.). L'Onchocercose bovine dans I'Amerique du Sud. 



[Bovine Onchocercosis in South AmeTka. ] — Recueil Med. Vet., 

 Paris, xcii, no. 14, 30th July 1916. [Received 30th April 1917.] 



Onchocercosis has been found to occur very frequently in South 

 America. Among cattle destined for preserved meat factories as 

 many as 70 or even 90 per cent, of the animals have been found to 

 be infected. 



Hendley (H.). Report on Malaria in the Punjab during the Year 

 1915, together with an Account of the Work of the Punjab Malaria 

 Bureau. Lahore, 1916. [Received 30th April 1917.] 



During the year 1915, the total fever mortality was 284,784. or a 

 death-rate of 14-72 per thousand of the population, as compared 

 with 345,471 (17-86 per thousand) in 1914 and 331,698 (1715 per 

 thousand) in 1913. No malaria occurred in an epidemic form in 1915 

 except in certain isolated areas. The localities that suffered most 

 were those along river banks, visited by local inundations. The 

 immediate effect of floods is to check the development of malaria by 

 the destruction of breeding places of Anophelines ; after the v/aters 

 have subsided, however, stationary collections of M^ater are left in 

 ditches and on uneven land, where the natural enemies of mosquitos 

 are rarely found, and it is in these temporary breeding places that 

 Anopbeline larvae develop, giving rise to epidemics. 



Some investigations were made during the year by the Punjab 

 Malaria Bureau in connection with the effect of cei-tain aromatic 

 plants on Anopheles, in the course of which it was discovered that the 

 smoke of saponified cresol was a very deadly culicide. A weak solution 

 was used in fire buckets and in small puddles and collections of water 

 and was found to destroy Anopheline larvae speedily, though the 

 pupae exhibited considerable resisting power and required 24 minutes' 

 exposure before they were killed. 



Tables and charts are given showing comparisons of spleen census 

 records, fever mortality, endemic and epidemic areas and maps of 

 the various Punjab districts under review.
