SALMON. 31 



says he, "of male Parrs with the milt matured, and 

 flowing in profusion from their bodies, being at all 

 times found in company with the adult female Salmon 

 while depositing her spawn in the river, and the female 

 Parrs being in every instance absent, suggested the 

 idea that the males were probably present with the 

 female Salmon at such seasons for sexual purposes. 



" To demonstrate the fact," he continues, "in January, 

 1837, 1 took a female Salmon Aveighing fourteen pounds 

 from the spawning bed, from whence I also took a male 

 Parr weighing one ounce and a half, with the milt of 

 which I impregnated a quantity of her ova, and placed 

 the whole in a private pond ; where, to my great as- 

 tonishment, the process succeeded in every respect, as 

 it had done with the ova which had been impregnated 

 by the adult male Salmon, and exhibited, from the first 

 visible appearance of the embryo fish up to their as- 

 suming their migratory dress, the utmost health and 

 vigour. 



" The result from this experiment was of so startling 

 a nature, that it was not thought prudent to give it 

 publicity till the trial was repeated. It was so, early 

 in the following January, 1838, when two lots of eggs of 

 a Salmon, weighing eighteen pounds, were impregnated 

 with the milt of two male Parrs, and there ensued pre- 

 cisely the same result as before. Again, in December, 

 1838, four lots of ova from an adult Salmon were im- 

 pregnated with the milt of four Parrs with similar 

 success ; and the same Parrs, being afterwards placed 

 in a private pond, assumed the migratory dress in the 

 following May, not in the most minute degree differing
