THE VICTORIAN NATURALIST. 163 



while Victoria is free from malaria, " Anopheles " occurs 

 commonly. He expressed the opinion that it would not be 

 a difficult matter to eradicate the mosquito by draining or 

 treating with kerosene all standing water, and introducing into 

 permanent water-pools, dams, &c., small fish, water insects, frogs, 

 &c. 



Mr. F. G. A. Barnard congratulated the author on the import- 

 ance of his discovery, and also Miss F. Bage on the able 

 manner in which she had executed the drawings to illustrate the 

 paper. 



Mr. J. Shephard spoke of the value of Mr. Leach's obser- 

 vations, but thought that the extermination of the mosquito 

 would be a very difficult matter to carry out successfully. 



Mr. J. A. Kershaw, F.E.S., stated that the National Museum 

 collection contained specimens of " Anopheles " collected near 

 Melbourne fully thirty years ago ; others were obtained from 

 Dandenong, Victoria, over twenty years ago. 



Mr. T. S. Hall, M.A., mentioned that Khartoum, once stricken 

 with malaria, has become free through the mosquitoes being 

 killed off with kerosene. 



Mr. G. A. Keartland and the chairman also spoke to the paper. 



Mr. Barnard apologized for not being prepared to read his 

 paper, which he stated would be ready for the next ordinary 

 meeting. 



NATURAL HISTORY NOTES.

 He also mentioned that specimens of the immature males of the 

 Satin Bovver-bird in the Gardens were showing the change of
