Contemporary quarter green morocco, marbled boards, gilt spine, marbled endleaves. A former owner added to Vol. I a CARTE-DE-VISITE PHOTOGRAPHIC PORTRAIT OF GERHARDT (ALBUMEN PRINT), taken by Ch. Winter of Strasbourg, with the dates of Gerhardt's birth and death added on the verso in the hand of Gerhardt's son Charles; the carte-de-visite has been inlaid to size on an inserted leaf. Also inserted is a 2-page ALS, dated January 1883 from Gerhardt's son to an unidentified correspondent, referring to the carte-de-visite. Bookplates of Haskell Norman. Fine. . FIRST EDITION. Gerhardt's major contributions to chemistry were his concept of homology, his reform of equivalents, his redefinition of acids based upon their displaceable hydrogen, and his new type theory, in which all organic compounds were considered as substitutionary derivatives of either water, ammonia, hydrogen or hydrogen chloride. This last had a powerful unifying effect on the development of chemical theory: first, by initiating a rapprochement between the formerly opposed radical and type concepts; and second, by allowing analogies of unprecedented generality between organic and inorganic compounds. Gerhardt's reform of equivalents, which removed inconsistencies in notation by dividing all four-volume organic formulas by two, earned him the enmity of many of his contemporaries. For fear that they would adversely affect its sale, he would not allow publication of the new formulas in his Traité. Only the last volume, published posthumously, makes use of the new notation.
