pleasure as well as instruction ; and we most cor- 

 dially recommend the series to such of our readers 

 as desire to obtain a general knowledge of Zoology. 

 It is with great pleasure that we see the great mas- 

 ters in science thus devoting their talents to the 

 task of instruction, instead of the more selfish occu- 

 pation of hoarding up stores of knowledge available 

 only to themselves." — We conclude by recommend- 

 ing the volume to the attentive perusal of the stu- 

 dent of Zoology. 



Treatise on the Geography and Classification of 

 Animals, by Wm. Swainson, Esq., A.C.G., 12mo. 

 6s. Longman and Co. London. 1835. 



The geographical distribution of animals is a 

 subject hitherto little attended to, and is ably 

 treated of in this useful and delightful volume. 

 The principles of the Quinary System are also 

 explained at some length, and we recommend this 

 volume as well as the Discourse to the attentive 

 perusal of the ornithological student ; as soon as 

 he has mastered all that is contained in these ex- 

 cellent and invaluable volumes, he may consider 

 himself a good Ornithologist, in the general prin- 

 ciples at least. The plan of these books appears 

 to us so original, and the execution of them so 

 masterly, that they cannot fail to be of the greatest 

 use to the Zoologist, and of the most extended 

 service to this branch of Natural Science. 



The following is a plan of the zoological volumes 

 to be published in Dr. Lardner's Cabinet Cyclopa- 

 dia. The two first have already appeared, and 

 are noticed above : —
