the mere statement of many of these, such as that accusing 

 him of aiding in poisoning Alexander, constitutes the most 

 effective refutation of them. The charge of aiding in 

 poisoning Alexander is mentioned by Pliny,* but it should 

 be mentioned, in justice to Pliny, that he himself was a 

 great admirer of Aristotle, and that he adds that the charge 

 was false and did great injustice to him. It can scarcely be 

 denied that Alexander died a natural death at Babylon. 



Of the numerous works which have been 



Aristotle s included among the Aristotelian treatises, 

 Writings on , , 1-1 



Natural Science, there are some which are considered to have 



been written, not by Aristotle but by his 

 pupils or followers. The determination of Aristotle s own 

 works has engaged the attention of many scholars, and has 

 been very difficult. This question has been considered from 

 almost every conceivable point of view, and, as regards 

 those works dealing with subjects which may be said to 

 belong to the Natural Sciences, it is now generally believed 

 that those mentioned below are genuine works of Aristotle. 

 The Greek titles and their usual Latin and English equi 

 valents are given in each case.
