‎First German edition (in the adaptation of Wislicenus) of van't Hoff's epoch making work ""La chimie dans l'espace"", published 1875 (a French expanded translation of his dissertation of 1874), and in which he established the fact that optically active substances contain at least one ""asymmetric"" carbon atom, that is, a carbon atom linked with four different kinds of atoms or radicals. Together here with the second, much expanded version and also WITH THE FIRST GERMAN EDITION OF OF ""Dix Années..."", which includes nearly three times as much material as the first edition (""La Chimie dans l'Espace""). ""His revolutionary ideas on the theory of the asymmetric carbon atom did not attract the attention of chemists, however, until Wislicenus asked van’t Hoff’s permission for a German translation by one of his pupils, Felix Herrmann.""(DSB).""In 1874, at the age of twenty-two, and with his Ph.D., as yet a few months in the future, he published a startling paper on the structure of organic compounds. Chemists had been puzzling for more than half a centurt over the fact that some organic compounds were optically active while others were not. As long ago as Biot there had been suggestion that this was due to some sort of assymetry, but the nature and location of that asymmetry remained a mystery. Pasteur had located the asymmetry in crystals, but that did not help with respect to the optical activity of subsatnces in soolution.Van't Hoff suggested that the symmetry exisyted in the molecules themselves. He drew four valences of the carbon atom (each represented as a short line or ""bond""), not two-dimensionally toward the four angles of a square, as Couper had done, but three-dimensionally toward the four angles of a tetrahedron. When the tetrahedral arrangement was considered, matters cleared up...""
