THE PASTEUR INSTITUTE 185 



phobia is installed on the ground floor; it in- 

 cludes a waiting room, an examination room, an 

 inoculation room, besides a laboratory, in which 

 are preserved the marrows of infected rabbits, 

 which are used for the preparation of vaccines. 

 In the left wing are situated a lecture room, a 

 laboratory for the preparation of culture 

 mediums and a dissecting room. The first floor 

 is given over to the course in the technical study 

 of microbes, and the second floor is used for the 

 researches of young scientists who have been 

 admitted for the purpose of carrying on their 

 personal studies. 



The active work of the Bacteriological Insti- 

 tute is divided into four main branches: the 

 department of vaccines, the department of hy- 

 drophobia, the department of technical mi- 

 crobiology, and the department of Metchnikoff. 



After the erection of the Bacteriological In- 

 stitute, the Serotherapic Institute was founded, 

 as a result of the discovery, by Dr. Roux, of the 

 vaccine for croup, and, next, the Institute of 

 Biological Chemistry.
