rant of the true nature of relations of analogy, imagined that 

 the Psittaceous tribe of Birds ought to occupy the first step in 

 the scale of nature below Man : but we cannot help adopting 

 the notion of Linnaeus in the Systema Nafura, — that although 

 not near him in construction, they are yet analogous to him in 

 various important respects. And, adopting this notion, we must 

 place the whole order of Insessores, to which Psittacus belongs, 

 opposite to the Primates, of which Man forms the type. \Vu:'j: . 



The analogies existing between Birds of Prey and Carnivo- 

 rous Quadrupeds having been noticed by Aristotle, who called 

 both groups yaf^-'pcovv^ot,, were enlarged upon by Plutarch*. 

 Among a host of moderns who have been struck with the 

 resemblance, I may particularly mention Linnaeus, who in his 

 Systema Natures has expressly called his Accipitres ^^Feris ana- 

 hgi ;" and BufFont, who has treated the subject at length and 

 with his usual eloquence. I conceive, therefore, that no one 

 can object to the propriety of my placing the Ferce opposite to 

 the Raptores. i: y/.'iZf :£"?> :e:: ::q;:'.i.:^ iu ,. 



The analogy between Aquatic Birds and Aquatic Mammalia 

 scarcely requires the mention of the authority of Linnaeus to 

 make it be granted. It is indeed so evident, that Hermann, 

 according to his custom, takes it for a relation of affinity :|.. 

 In both orders the anterior appendages of the vertebral axis 

 dwindling into fins, and the two undivided posterior appen- 

 dages being placed so far behind on the axis as to show that 

 both were intended for motion in the water rather than on 

 land, are circumstances of themselves sufficient to authorize 

 the placing of the Cetacea opposite to the Natatores. 



Two orders still remain in each class to be considered : the 

 Glires and Ungidata among the Mammalia; and among Birds,
