During his life of labor, filled with privations and mortifications, 
Alexis Sauvage met with a severe accident. In 1849, he was badly 
injured by the explosion of the Telescope Gasometer at the Opera. In the 
midst of the general fright, he did not hesitate to face the flames, and, at 
the peril of his life, go and close the valves of the gasometer; he thus 
saved from immediate destruction a quarter of Paris, as also the whole 
equipment of the theatre. The horrible burns he then got led him pre- 
maturely to the grave. And how did the English Gas Company mani- 
fest their gratitude towards one rendered infirm in their service? Did it 
not at least assure him of bread for the rest of his life? They ordered 
im a bronze medal and let him go to the hospital. 
_ Incapable of work, and failing to obtain justice, Mr. Sauvage applied to 
the courts ; and it was not until six years had passed, in 1855, that the 
English Company was condemned to pay a pension for his support of 
1200 franes.
