The students (90) grow medicinal plants, collecting, drying, preparing extracts, and then distilling then, in order to produce drugs. As at Lyon, the garden was very important for the veterinary science, producing treatments for use in animals. |

| 1914 |
|Military occupation of the school. Part of the Botanic Garden is transformed into a vegetable garden. |
| 1930 ||The Botanic Garden looses 4000m2, due to the building of a new science laboratory. |
