88 Investigations on the I/ife- History 



FEMALE SALMON- 1895. 



Table III. gives the results of the analyses of the amount of solids 

 in the North Esk fish during 1895. 



It corresponds closely to Table I., except as to the solids of the 

 ovaries. Here in July both the percentage amount and the amount per 

 fish of standard length are markedly higher than in the corresponding 

 fish of 1896. 



MALE FISH. 



Though the testes increase in size about twenty fold, they do not 

 attain anything like the same proportionate weight of the fish as do the 

 ovaries. In a fish of standard length in the male, 257 grins. 

 of material are laid on to the testes; in the female, 2150 grms. are 

 gained by the ovaries. It is, therefore, highly probable that since the 

 muscles in the female contain sufficient material for the growth of the 

 ovaries, in the male the stored material should be amply sufficient 

 for the growth of the testes. Unfortunately the number of male 

 salmon at our disposal was small. 



Table IV. gives the results of our investigations on the changes < f 

 the solids in the muscle and testes :
