PAPERS. 



By Miss G. Sweet, M.Sc. (communicated by G. Sweet, F.G.S.), 

 entitled " Mosquitos and Disease." 



The author described the main features of the principal genera 

 of mosquitos, and then pointed out how certain diseases had 

 been traced to the infection carried to healthy individuals by 

 mosquitos from persons already attacked, and said that it is 

 probable other diseases will be found to have been spread by 

 similar means. 



In the discussion which ensued, in which Miss Sweet was 

 complimented on the interesting nature of her paper, Mr. D. Le 

 Souef, C.M.Z.S., mentioned the practice adopted by residents in 

 Queensland in allowing swallows to build their nests about their 

 houses for the purpose of encouraging them to remain in the 

 district and so help to keep down the numbers of mosquitos.

 blindness in the horses and camels, unless the precaution is 

 taken of rubbing the animals with castor oil. 



Mr. J. Shephard instanced a water tank in which the water was 

 sometimes nearly boiling, but in which the larvae of mosquitos 

 flourished. 



Mr. A. D. Hardy stated that he had lived for some months in 

 the Niger Coast Protectorate (now Southern Nigeria), West 

 Africa, a country rendered almost uninhabitable for the white 

 man by fever, and mentioned that it was from Major Ross, who 

 represented the School of Tropical Medicine, Liverpool, that 

 many had first heard that mosquitos, and more particularly 

 the genus Anopheles, were responsible for the transference of the 

 fever germ, and that the genus Culex was innocent of the evil. 

 Prior to this being made known it had been noticed that when
