"He is a learned man," said old Parson Emmons of Franklin, "who understands one subject, and he is a very learned man who understands two subjects." Schonbein says he has been studying oxygen for thirty years. Mitscherlich said it took fourteen years to establish a new fact in chemistry.
Some years ago, in 1832, a French chemist, Braconnot, discovered this substance, which he called xyloidine. In 1838, another Frenchman, Pelouze, studied its different properties; and lastly, in 1846, Schonbein, professor of chemistry at Basle, proposed it as gunpowder. This powder is nitric cotton." "Or pyroxyle," answered Elphinstone. "Or fulminating cotton," replied Morgan.
These substances were formerly thought to be nitro-substitution compounds, but are now known to belong to the compound ethers of nitric acid. Gun-cotton, discovered by Schonbein, in 1845, has since been looked upon as the most promising material for a smokeless gunpowder, it being a very powerful explosive and burning with practically no smoke.
You are young, I am old.... But then our subjects are so glorious, that to work at them rejoices and encourages the feeblest; delights and enchants the strongest. 'I have not yet seen anything from Magnus. Thoughts of him always delight me. We shall look at his black sulphur together. I heard from Schonbein the other day. He tells me that Liebig is full of ozone, i.e., of allotropic oxygen.
He was not one of those beings who would emulate a Schonbein or Friar Bacon, or act the part of an incendiary towards the Thames, his neighbour but a good, kind, simple, honest, easy fellow in love with his wife well disposed to all the world content with himself, content even with his mother-in-law.

Huygens declared that, were it not for an unforeseen combination of circumstances, the invention of the telescope would require "a superhuman genius;" it is known that we owe it to children who were playing with pieces of glass in an optician's shop. Schönbein discovered ozone, thanks to the phosphorous odor of air traversed by electric sparks.
In 1838 another Frenchman, Pelouze, investigated its different properties, and finally, in 1846, Schonbein, professor of chemistry at Bale, proposed its employment for purposes of war.
