HALLER AND LEIBNITZ. 39 



[Nulla est epigenesis). No part of the animal body was made 

 previous to another, and all were created simultaneously 

 (Nulla in corpore animali pars ante aliam facta est, 

 et ovines shnid creatw existunt)." In reality, therefore, 

 he denied any actual evolution in the natural sense, and 

 in this went so far as to maintain even the existence of a 

 beard in the new-born boy, and the existence of the horns 

 in the hornless fawn ; all the parts were already present 

 in a complete state, but hidden for a while from the human

 drawn from it, most successfully, even after Wolff had dis- 

 covered the true Epigenesis, and proved it by investigation. 

 Leibnitz was the most important of the philosophers 

 who adopted the Theory of Evolution (Pre-formation), and 

 by his great authority, as well as by his talented exposition,

 the Theory of Encasement to the soul also, and denied all 

 real development for it, equally with the body. In his 

 Theodicce, for instance, he says : " I think that souls, which 

 will some day be human souls, as in the case of those of
