Becquerel, Ebelman, Brewster, Dumas, Milne-Edwards, Saint-Claire-Deville frequently consulted him upon the most difficult problems in chemistry, a science which was indebted to him for considerable discoveries, for in 1853 there had appeared at Leipzig an imposing folio by Otto Liedenbrock, entitled, "A Treatise upon Transcendental Chemistry," with plates; a work, however, which failed to cover its expenses.
MM. Becquerel, Ebelmen, Brewater, Dumas, Milne-Edwards, aimaient à le consulter sur des questions les plus palpitantes de la chimie. Cette science lui devait d'assez belles découvertes, et, en 1853, il avait paru à Leipzig un _Traité de Cristallographie transcendante_, par le professeur Otto Lidenbrock, grand in-folio avec planches, qui cependant ne fit pas ses frais.
