BOOK NOTICES. 



Aristotle's Researches in Natural Science, by Thomas 

 East Lones, M.A., LL.D., B.Sc. London. West, Newman & 

 Co., 191 2. 8vo, pp. 274. Price 6s. net. 



The author of this interesting work has been at great pains to 

 gather together in readable form the curious, but often surprisingly 

 accurate, ideas of the well-known Greek philosopher which are 

 scattered over his numerous works on various branches of Natural 

 Science. The result is very satisfactory, for we are furnished with a 

 concise view such as could only be obtained by the reader with the 

 expenditure of much laborious research. Aristotle's notions 

 regarding any particular organism, structure, or phenomenon can 

 here be readily found, by the help of a good index and innumerable 

 footnotes. Thus, if the reader desires to know what the philosopher 

 thought about the Ostrich, we turn up the three references given in 

 the index, and find at once a brief summary of all that he said 

 about such a bird, while the footnotes enable one to find readily the 

 actual passages in the original text. We should recommend the use 

 of this volume along with one or other of the excellent translations 

 which have recently been published.
