in drift-nets ; but even then it is only one at a time 

 and at considerable intervals. It is in no estima- 

 tion as food.

 thorax, formed by scales larger and coarser than 

 those of the rest of the body ; the sides of the tail

 into the nets and do considerable damage. One was

 (Loudon's Mag., vi.) that one was taken nearly op- 

 posite Greenock, in the herring-nets, which measured 

 nine feet in length, in July 1831 ; and within the last 

 few weeks, a beautiful specimen, also Scotch, 8 feet 

 long and 5 feet 6 inches in circumference, has been 

 added to the Collection in the Edinburgh University 

 Museum. The flesh of this fish was dressed, and
