The progress of natural science necessitated the creation 

 of a special professorship of botanical science which was 

 entrusted to Mr. Em. Laurent who established a labora- 

 tory of instruction for the students in which the latter 

 devote several hours

BOTANICAL LABORATORY 



The collections of living plants at the Institute have 

 increased so considerably in the last ten years that to day 

 they constitute a genuine botanical garden worthy of a 

 university. 



In this garden may be seen a collection of plants from 

 equatorial Africa and of the economic plants of the 

 tropical regions. 



The botanical laboratory also serves as a station for 

 vegetable pathology. 



Mr. Marchal is at the head of this station. 



The teaching of zoology and entomology is directed to 

 give the students a knowledge of the grand divisions 

 of zoology by studying one t}^pe of each of them. 



A laboratory with rich entomological collections has 

 been established for the benefit of the students and the 

 public. 



This service promises to be considerably extended each 

 year.
