44 REPORT ON ARTIFICIAL FISH-CULTURE.

 and bestowed on each of these worthy men an 

 honorary medal. The work they proposed it seems 

 to me they fully succeeded in, and to render 

 their country great service they only need the 

 means to extend their operations. I do not judge 

 solely by the results obtained by Gehin and Remy, 

 but also by similar ones on a large scale, which 

 I found to have been obtained for several years 

 past in Great Britain, and which had excited 

 there considerable interest. 



In fact, M. Boccius, a civil engineer of Ham- 

 mersmith, has practised artificial fecundation in 

 stocking several rivers in Great Britain, and 

 seems to have had complete success. 



In 1841 he worked in the streams belonging 

 to Mr. Drummond, in the neighborhood of Ux-
