First appearance of a classic paper on the theory of organic chemistry, being one of the main works to introduce the importence of "radicals" in chemical reactions.

"Perhaps Duma's chief contribution to the theory of organic chemistry. In 1828, in collaboration with Polydore Boullay, he published a research on the esters of ethyl alcohol (the paper offered) wherein he showed that these compounds could be looked upon as salts of ethylene and acids, as reported in the first extract.On the basis of tis work, Berzelius in 1832 called ethylene a radical which he named aetherin and which took an importent place among the growing number of organic radicals."(Leicester & Klickstein p. 320 ff). - Parkinson "Breakthroughs", 1828 C.
