On the increase of the Nile, a small book by Aristotle. [Footnote:
_De inundatione Nili_, is quoted here and by others as a work of
Aristotle. The Greek original is lost, but a Latin version of the
beginning exists (Arist. Opp. IV p. 213 ed. Did. Par.).

In his quotations from Aristotle Leonardo possibly refers to one of
the following editions: _Aristotelis libri IV de coelo et mundo; de
anima libri III; libri VIII physi- corum; libri de generatione et
corruptione; de sensu et sensato... omnia latine, interprete
Averroe, Venetiis 1483_ (first Latin edition). There is also a
separate edition of _Liber de coelo et mundo_, dated 1473.]
