Carpenter' s Vegetable Physiology. Edited by Dr. Lankester. 

 New Edition. London : H. G. Bohn. 



This work on Vegetable Physiology, by the most eminent phy- 

 siologist of the day, is not a rival to the excellent introductory 

 works of Dr. Lindley, Professor Balfour, Jussieu's Cours Ele- 

 mentaire, Schleiden^s profound works, etc. etc. : it is a totally 

 distinct and different treatise. 



It is divided into two parts : — 1. Vegetable Physiology. 2. Bo- 

 tany, structural or organic, and systematic. 



Some might question the fitness of the arrangement, and main- 

 tain that the structure or anatomy of vegetation should precede 

 the description of the functions, habits, and characteristics of their 

 vital agencies. But, as before said, this is a work sui generis, and 

 only one of a series descriptive of the laws of living organisms. 



The author, in his preface, states that the physiology of man 

 cannot be understood unless viewed in connection with that of 

 the humbler orders of the animate, sentient creation; so the 

 physiology of animals cannot be successfully studied, except in 

 connection with vegetable physiology. 



The editor of this new edition has modified, we presume, some 

 of the author's vievvs about circulation, descent of the sap, etc. 

 He has dealt tenderly with the subject ; and his own views on 

 these mysterious points are not very prominently put forward. 



The author's distinctive characters, both of inorganic and or- 

 ganic objects, are all derived from his favourite theme. Physiology. 

 The various accidents of form, dimensions, or extension and du- 

 ration, do not figure among his distinctive characters. These ex- 

 ternal and obvious marks are fully as conclusive, and far more 

 easily apprehended than the more recondite physiological facts.
