‎First apperance in print of Laurent's announcement of his fundamental discovery, rejected at first by the Academy, in which he ""converted Dumas' theory into a real theory of substitution by making the importent addition that when a compound undergoes chlorination, the chlorine takes the place , and, as it were, plays the part of the hydrogen, which is removed."" (Findlay).Laurent demomstrates that a chlorine atom can be substituted for a hydrogen atom in a chemical with little change in properties. As this refutes the prevailing concept, his work is rejected by the chemical community at first. (Bunch 1836 C).‎
