66 PISHES AND FISHING. 



patrician tables, or were preserved in ponds to be 

 angled for by Roman nobles, and even emperors.

 Columella was a philosopher of Cadiz, and was the

 about A.D. 43. 



I do not pretend to decide to whom we owe the 

 revival or the invention of the method of breeding fish 

 artificially in our country ; but I think Mr. Boccius 

 has certainly brought it to great perfection in the 

 south, as many gentlemen have in the north, and on 

 the continent, and they have very much simplified 

 the process : his work on the subject, published by 

 Van Yoorst, of Paternoster Row, Mr. Ashworth's, and 

 those of several other men of science, are very expla 

 natory, and to which I must refer. 



Samuel Gurney, Esq., Jun., a few years ago, gave me 

 the egg of a trout, which had been thus artificially 

 vivified in the river Wandle, upon the plan of Mr. 

 Boccius. A sort of fine fin was attached to the egg, 

 which was of a light reddish stone-colour, so far 

 transparent, that the circulation of the blood in a pul 

 satory manner could be seen by a magnifying glass of 

 very moderate power. The phial in which it was, 

 being placed in a horizontal position, it moved from 

 end to end with great velocity, but for want of a proper 

 current of aerated water, it only lived a few days.
