First printing of Balard's famous memoire in which he records his discovery of the new element Bromine (le brôme). While he was studying the flora of a salt marsh, he notized a deposit of sodium saulfate which had crystallized out in a pan containing mother liquer from common salts.

His investigation of this phenomenon,...ked to the remarkable discovery....(Weeks p. 264).

"The discovery of a new chemical element by a young and obscure provincial pharmacist caused a sensation in Paris. Balard's achievemnt was recognized by the Academie des Sciences and he was awarded a medal by the Royal Society of London."(DSB I, p. 416).

"The discovery of bromine is a very importent acquisition to chemistry, and gives M. Balrad honorable rank inthe career of the sciences. We are of the opinion that this young chemist is every way worthy of the encouragement of the Academy, and we have the honour to propose that his memoir shall be printed in the "Recueil des Savants Étrangers" (The report from the French Academy, signed by Vaugelin, Thenard, and Gay-Lussac).
