PENNANT, 1781. 



'History of Quadrupeds,' Vol. I. 4to. London. 



Thomas Pennant, to whom Gilbert White addressed some of his most 

 entertaining letters on the 'Natural History of Selbourne,' was the author of 

 an excellent work of 566 pages on quadrupeds, containing descriptions of 

 over 400 species of mammals and adorned with fifty-two plates of fairly 

 good execution. 



In the descriptive part the work was a worthy successor of that of Ray 

 and long remained the standard in England. The classification adopted 

 is merely an adaptation and simplification of Ray's system, with some 

 modern additions. It is what might be called a "common sense" system, 

 very practical and convenient, but bare of new principles, and without 

 appreciation of the essential superiority of some of Linne's best ideas. 



This is shown in the author's introduction. After discussing the classi- 

 fications of Ray, Klein and Brisson, he goes on to speak of Linne's system 

 as follows: 



"There are faults in his arrangement of Mammalia ^ that oblige me to 

 separate myself in this one instance from his crowd of votaries .... I reject 

 his first division, which he call Primates or Chiefs of Creation; because my 

 vanity will not suffer me to rank mankind with Apes, Monkeys, Maucaucos 

 [Lemurs] and Bats, the companions Linn^us has alloted us even in his last 

 System." He admits that "Whales have in many respects the structure of 

 land animals; but their want of hair and feet, their fish-like form and their 



1 " Or animals which have paps and suckle their young; in which class are comprehended 

 not only all the genuine quadrupeds but even the Cetaceous tribe."
