330 THE GREAT UNKNOWN". 



" I have inquired repeatedly whether the natural history 

 collections of Boston, Philadelphia, or other cities of the 

 United States, might possess any unusually large ophidian 

 vertebrae, or any of such peculiar form as to indicate some 

 large and unknown marine animal ; but they have re-

 great sea-serpent, and which are now in Berlin, belonged
