Aristotle's researches in Natural Science are set forth 

 in a series of his works, some of which have ah'eady received 

 a great deal of attention, while the rest have been much 

 neglected. Translations, with or without explanatory notes, 

 of all these works have been produced in English, French, 

 German, or Latin, and separate treatises or papers discuss- 

 ing Aristotle's researches in one or more branches of Natural 

 Science have been published from time to time. Among 

 such treatises and papers may be mentioned J. Miiller's
