THE NEW AKT OF BREEDING FISH. 43 



Every one will admit, that if the process of arti-

To make known this valuable discovery ; perfect

 shall need them for experiments, the fecundated eggs 

 of the establishment at Huningen, in order to excite 

 emulation ; this is the part which, in conjunction 

 with Messrs. Berthot and Detzem, I have taken 

 upon myself in organizing fish-culture. 



If I may judge from the evidences of good will 

 which I am receiving from every part of France, and

 But artificial fecundation constitutes only one branch 

 of the subject ; with regard to rearing aquatic ani- 

 mals there are others no less important, which I 

 hope soon to succeed in making equally celebrated. 



This publication, then,- is but the first chapter 

 of the labors I am engaged in, but a response to 

 many demands for information which my occupa-
