We are told by an American Reviewer (Mr. Lacerde. 

 Robert Fletcher) that, "Dr. J. B. de Lacerda, 

 Director of the Physiological Laboratory of the 

 National Museum of Rio Janeiro, has been, dur- 

 ing the last ten years, experimenting with the 

 venom of Brazilian snakes, especially with that 

 of bothrops jararacassu, a serpent which closely 

 resembles its congener, the North American 

 crotalus, in the intensity of action of its venom. 

 During that time, he has made several commu- 

 nications to the French Academy of Sciences."
