 examination the generality of naturalists have decided that in 

 its affinities it stands in nearer alliance to fishes, and especially 

 that in a descending scale it bears a close alliance to the 

 family of Lampreys, yet there are so many peculiarities in its 

 formation and prominent appearance, that we can place it only 

 on that intermediate ground which leads from one of these 

 great families to the other; while in some respects it seems 

 to stand alone, as well in its structure as habits, as if to shew,

 nature of each, has still united the apparently discordant
