130 FISH HATCHING. 



The physiological cause of these double 

 fish, T am at a loss to explain. Both Mr. 

 Ponder and myself, however, are of opinion 

 (until a better reason can be found) that the 

 cause of the Jmmp-hacJced and otherwise 

 deformed fish, is pressure received during 

 their transport in the egg state from Hu- 

 ningue, the soft embryo having been in 

 somewhat bent or damaged by the adjacent 

 moss or eggs. This seems probable, as out 

 of the 27,000 trout eggs which were taken 

 by Mr. Ponder, and carefully carried in 

 water home by hand, and deposited in the 

 boxes a few hours after they were taken, 

 there are no cripples and no double-bodied 

 fish, but, instead, they are all healthy, straight- 

 backed, active little creatures.
