to the flesh; and were particularly zealous in fattening them to 

 the largest possible size. Another branch of the art was likewise 

 studied with great attention ; it was that of acclimationj or the 

 breeding of salt-water fish in lakes and fresh-water rivers. This 

 was, in many instances, as may be supposed, a Work of some dif- 

 ficulty ; but the arts of the epicure, in those ancient times, were 

 many, and generally very successful. We need scarcely, how- 

 ever, extend our researches into the knowledge of the ancient 

 Romans or Chinese on this subject ; it is not the antiquarian, but 

 the modern phase of pisciculture, particularly in its utilitarian 

 aspect, with which we have business. 



" The honour of being the modern discoverer of this long-for- 

 gotten art undoubtedly belongs to M. Jacobi, who published, in 

 1763, a minute Snd interesting account of his thirty year's prac- 

 tice. This gentleman was not satisfied with his discovery as a 

 mere scientific curiosity, for to him also belongs the still greater 

 merit of making the art commercially useful as a means of keep- 

 ing up the supplies. At the date we have indicated, great at- 

 tention was devoted to pisciculture by various gentlemen of scien- 

 tific eminence. Count Goldstein wrote on the subject to M. de 

 Pourcroy, and Duhamel du Monceau gave it publicity in his trea- 

 tise on fishes. The Journal of Hanover also had papers on this 

 art, and an account of Jacobi's proceedings was likewise enrolled 

 in the memoirs of the Royal Academy of Berlin. The discovery 

 of Jacobi was the simple result of a keen observation of the na- 

 tural action of the breeding-salmon. Observing that the process 

 of impregnation was entirely an external act, he saw at once 

 that this could be easily imitated by careful manipulation ; so that 

 by conducting artificial hatching on a large scale, a constant and 

 unfailing supply of fish might readily be obtained. The results 

 arrived at by Jacobi were of vast importance, and obtained not 

 only the recognition of his government but also the more solid 

 reward of a pension. 



" The labours of Gehin and Remy deserve generous record, for 

 it is to their exertions we are most indebted for the activity and en- 

 terprise which are now displayed in the art of hatching and breed-
