them return to the hive. If the right testicle of a ram 87 is 

 tied up, he will generate females only. Persons who have 

 about them the sinews taken from the wings or legs of a crane, 

 will never be fatigued with any kind of laborious exertion. 

 Mules will never kick when they have drunk wine. 



Of all known substances, it is a mule's 88 hoofs only that are 

 not corroded by the poisonous waters of the fountain Styx : a 

 memorable discovery made by Aristotle, 89 to his great infamy, 

 on the occasion when Antipater sent some of this water to 

 Alexander the Great, for the purpose of poisoning him. 



We will now pass on to the aquatic productions.

 97 An eminent philosopher, a native of Smyrna, and disciple of Calli- 



machus. He flourished about the middle of the third century B.C., and 

 left numerous works, the principal of which was a Biography of the Phi- 

 losophers, Poets, and Historians, which seems to have been highly esteemed. 

 It is thought, too, that he wrote a work on Magic and Astrology ; but there 

 are some doubts about the writer's identity. 



95 A native of Oasis in Egypt, who taught rhetoric at Rome in the reigns 

 of Tiberius and Claudius. Some curious particulars are given respecting 

 him in c. 6 of the present Book. His ostentation, vanity, and insolent 

 pretensions fully merited the title " Cymbalum mundi," which Tiberius 

 bestowed on him. He was a man, however, of considerable learning and 

 great eloquence, and was distinguished for his hatred to the Jews. Of his 

 numerous works only some fragments remain.
