80 SALMONIA. 



touched field of investigation, which I hope 

 will soon be taken up by some enlightened 

 country gentleman, who in this way might 

 make not only curious but useful discoveries. 



POIET. So much science would be re- 

 quired to make these experiments with suc- 

 cess, and there would be so many difficulties 

 in the way of preserving fishes at the time 

 they are proper for reproduction, that I fear 

 very few country gentlemen would be capable 

 of prosecuting the inquiry. 



HAL. The science required for this object 

 is easily attained, and the difficulties are quite 

 imaginary. The impregnation of the ova of 

 fishes is performed out of the body, and it is 

 only necessary to pour the seminal liquor from 

 the melt upon the ova in water. Mr. Ja- 

 cobi, a German gentleman, who made many 

 years ago experiments on the increase of trout 

 and salmon, informs us, that the ova and melt 

 of mature fish, recently dead, will produce 

 living offspring. His plan of raising trout 

 from the egg was a very simple one. He had 

 a box made with a small wire grating at one 

 end in the cover, for admitting water from a
