FISHES OF THE FIRTH OF FORTH. 



Forth it is very rare, the only instance I am aware of its 

 capture in the estuary Avas during the month of August, near 

 Queensferry, where it was found in a pool of water left by 

 the recedino- of the tide ; occasionally it is taken beyond the 

 Isle of May and brought to the Edinburgh Market. The 

 ova in the month of January appear to be in a fit state to be 

 deposited. Its food is crustaceous animals and small fishes ; 

 its flesh is firm and wholesome, and is considered by some 

 to be superior tothe last species, but in general more dry. 

 In the north of Europe it is salted for keeping ; it is out of 

 season in December, January, and February.
