SINCLAIR ON PISCICULTURE. 29 



of the European and American continents, although they were less 

 dissimilar from one another than either from modern iish. Some 

 of the ganoid fishes had a vertebrated neck, and were thus able to 

 look about them. 



The same similarity prevails in the present day, when man is 

 present to take advantage of it. The great siluris glanis of the 

 Danube, whose introduction into Great Britain has caused atten- 

 tion, is undoubtedly one of the types of the large Channel cat fish 

 of America, probably distinguished by some local peculiarity. The 

 sturgeon of the Danube is most likely the same as the St. Law- 

 rence sturgeon, with a difierence. 



Many of the European fish, if introduced here, might deteriorate 

 in size and quality ; but, considering the extent, purity, and varied 

 conditions of our lakes, on the average, quite a contrary result may 

 be confidently anticipated.
