Fabre's Book of Insects

My first introduction to chemistry was less fortunate. It ended in the bursting of a glass vessel, with the result that most of my fellow-pupils were hurt, one of them nearly lost his sight, the lecturer’s clothes were burnt to pieces, and the wall of the lecture-room was splashed with stains. Later on, when I returned to that room, no longer as a pupil but as a master, the splashes were still there. On that occasion I learnt one thing at least. Ever after, when I made experiments of that kind, I kept my pupils at a distance.
