adopted by him in the management of his fish, 
together with some other details connected with 
it, which cannot, I think, fail to be generally 
interesting.

from which finds its way into the larger one,

weight, and their quality is precisely the same 
as that of river-fish, although it contains no

through), being the probable causes of their
