 teur became interested in those investigations 

 of the subject of molecular dissymmetry 

 which were the starting-point of so many won- 

 derful discoveries." ^ 



Does It not seem that there must be a spe- 

 cial Providence for the elect of science? 



In Dufour's memoir, which gave Fabre so 

 decisive an impulsion toward entomology, a 

 singular fact is mentioned: the naturalist of 

 the Landes found In the nest of a species of 

 Wasp known as the Cerceris some small bee- 

 tles of the Buprestis family, which, although 

 apparently dead, remained as fresh as though 

 alive during the period occupied by the rear-
