 and such-like artificial or natural obstructions ; however, it is 

 now known that such is not invariably the case, for in some 

 instances, doubtless, like the sea trout, it at all events visits 

 the tidal waters ; and yet, as we shall see, like the smelt, white 

 fishes, cusk, etc., it can also prosper and multiply without 

 going into salt water.

 in these respects are owing to its restriction to fresh water. 

 I shall, therefore, now proceed to show the anatomical 

 distinctions between the two and other salmonoids of the 

 North American continent.
