40 MEMOIR OF GESNER. 



learning had procured him, encouraged his design 

 by transmitting specimens, and remarks on the ani- 

 mals of their respective countries.* The jour- 

 neys also which he had an opportimity of making,

The work in question is divided into five books, 

 generally bound up, as he himself recommended, in

 the third, of the date 1 555, of birds ; and the fourth, 

 1556, of fishes and other aquatic animals. The 

 fifth part was a posthumous publication, drawn up 

 from Gesner s manuscripts by James Carron, a phy-

 others; it treats of serpents, and has usually ap- 

 pended to it a treatise on the scorpion, published 

 from our author's papers under the superintendence 

 of Caspar Wolf. The two latter treatises did not 

 appear till 1587, that is, twenty-two years after 

 the author's decease.

 Jo. Caius, medicus Londini clarissimus ; Jo. Fauconerus, An- 

 glus ; Jo. Parkhurstus, Anglus, theologus et poeta elegantissi- 

 mus : and Theodorus Beza.
