mon to the Herring. This happens in our own country ; in other 

 countries there are perhaps some other fishes which more com- 

 pletely supply the link between these two most important tribes. 

 Captain FRANKLIN and his intrepid party, who twice visited the 

 Arctic Regions of America, mentions their subsisting mostly 

 through the winter on a fish called the Herring Salmon of the 

 Bear Lake. I have not seen this fish nor any delineations of it, 

 but presume it to have been a Corregonus closely allied to the 

 salmon and herring, and constituting an intermediate link con- 

 necting these two great families. 



SECTION II. 



The admirable flavour of the true salmon, his profuse increase 

 and value in the market, render his food and extent of migra- 

 tion worthy objects of the most careful inquiry. This was, how- 

 ever, surrounded with great difficulties, and had given rise to 

 many opinions more or less probable, but all in their essence con- 

 jectural, or nearly so. As a proof of the difficulty of the inquiry, 

 it being unnecessary to cite more here, I shall content myself with 

 quoting a passage from a very recent work (1833,) on Natural 

 History, " The Complete Angler of IZAAK WALTON," edited by 

 Mr RENNIE, Professor of Zoology, King's College, London. In 

 1653, WALTON found nothing in the stomach of the Fordige 

 Trout ; and in a note, in the year 1833, Mr RENNIE adds, " The 

 same is true of the salmon, which has never any thing be- 

 sides a yellow fluid in his stomach when caught : the same is also 

 true of the herring." The food of the true salmon, on which 

 all his estimable qualities, and in my opinion, his very existence, 

 depend, and which he can obtain only in the ocean, we have 

 found to be the ova or eggs of various kinds of the echinoder- 

 mata, and of some of the Crustacea. From the richness of the 

 food on which the true salmon solely subsists, arises, at least to
