THE ARTIFICIAL PRODUCTION OF FISH. By PISCARIUS. 

 Third Edition. Price Is. 



" The object of this little book is to make known the means by which fish of 



all descriptions may be multiplied in rivers to an almost incalculable extent 



This principle of increase Piscarius has carried out by argument and experiment 

 in his li'tte treatise, which, we think, is worthy the attention of the legislator, 

 the country gentleman, and the clergyman ; for it shows how an immense addi- 

 tion may be made to the people's food with scarcely any expense." Era.
