fertilization by the fish-culturists. The 

 Salmonidce have always occupied their 

 chief interest. 



The centers of such hybridization have 

 been the experiments of Sir James Mait- 

 land. at Howietoun recorded by Day and 

 those of Seth Green of the New York hatch- 

 ery, cited below and further recorded by R. 

 B. Roosevelt in Proc. Amer. Assoc. Adv. 

 Science, 1884, vol. 33, pp. 510-515.

 (eggs) and salmon. Day, F. 1882.4, 1885.8.
