In these papers he shows for the first time how to determine equal weights of substances that all acids differ only in water content and that dry acids combines in equal proportions with alkali. In the first paper he also gives the Pygnometer Bottle its modern form."Probably his most importent work was on the strenght of acids and the quantity required to neutralize a given quantity of alkali two papers published in 1699 and 1700 - the papers offered - Homberg recognized that different alkalis neutralized the same acid in different proportion but believed that the relative strenghts of two acids could be determined by using the same alkali in each case. he treated the the question of neutralization or dissolvability as he called it in quite quantitative fashion showing that if an alkaline salt were treated with an acid the gain of weight ofthe salt wasan indication of the amount of acid absorbed.Homberg nevertheless understood the fundamentals of the process and thereby laid the foundation for an understanding the nature of salts."DSB VI p. 478.Parkinson "Breakthroughs" 1700 C. </em> unknown

Many textillustrations of apparatus in woodcut. <br/><br/><em>First appearance of the paper in which Moissan describes his isolation and observation of the properties of fluorine gas and his succes in producing diamond with his pectacular arc method. Fo these achievements he was the first French to be awarded the Nobel Price in chemistry 1906.The existence of the element fluorine had been well known for many years but all attempts to isolate it had failed and some experimenters had died in the attempt."Moissan eventually succeeded in preparing fluorine in 1886 by the electrolysis of a solution of potassium hydrogen difluoride KHF2 in liquid hydrogen fluoride HF. The mixture was needed because hydrogen fluoride is a non-conductor. The device was built with platinum/iridium electrodes in a platinum holder and the apparatus was cooled to -50 °C. The result was to completely isolate the hydrogen produced from the negative electrode from the fluorine produced at the positive one.This is essentially still the way fluorine is produced today."

Wöhler & Liebig's paper: pp. 225-336. Clean and fine. small stamps to verso of titlepage. <br/><br/><em>First French edition of this importent paper in the development of organic chemistry. It is the last joint paper of importence from "these two men .pioneers in the development of organic chemistry form a twin constellation in the chemical firmament"Alexander Findley in "A Hundred Years of Chemistry" p. 23. The paper is a translation of "Untersuchungen über die Natur der Harnsäure" published at the same time in Justus Liebigs Annalen der Chemie 1838 Wöhler and Liebig collaborated on one more major piece of work a study of uric acid. The paper offered. Wöhler suggested the subject and the idea seems to have come from his medical interests. Uric acid was not easily obtainable–snake excrement was the only substantial source–and relationships with urea and allantoin were suspected by Wöhler. As a student he had won a prize in 1828 for an essay on the conversion in the human body of chemicals taken orally and excreted in urine. The technique adopted by Liebig and Wöhler was to subject uric acid ad the derivatives they prepared to oxidation and reduction by reagents of different concentrations and strengths. Wöhler seems to have been the first to heat reagents together in sealed glass tubes but after an explosion he thought metal ones safer.Their 100-page paper described fourteen new compounds and their preparation and analysis.7 An attempt to establish a new radical called "uril" C8N4O4 was less successful. Perhaps even more significant than the sophisticated practical and theoretical organic chemistry was the new spirit revealed. Writing to Berzelius in 1828 Wöhler was doubtful whether animal substances could be prepared in the laboratory. In 1832 he began the paper on the benzoyl radical with a description of organic chemistry as "the dark region of organic nature." But in 1838 his work with Liebig led him to write at Liebig’s suggestion: "The philosophy of chemistry will conclude from this work that it must be held not only as probable but as certain that all organic substances insofar as they no longer belong to the organism will be prepared in the laboratory. Sugar salicin morphine will be produced artificially. It is true that the route to these and products is not yet clear to us because the intermediaries from which these materials develop are still unknown but we shall learn to know them."DSB. </em> hardcover
182844898Paris Crochard 1828. 8vo. Without wrappers. Extract from 'Annales de Chimie et de Physique' Series 2 - Volume 37. Pp. 330-334. <br/><br/><em>First appearance in French of this milestone paper marking the beginnings of organic chemistry in which Wöhler describes how he managed to synthezise urea from cyanate of ammonia. The French version here is translated from the German paper "Ueber künstliche Bildung des Harnstoffs." which was issued the same year 1828. This broke down the old distinction between organic and inorganic substances. "This was the first synthesis of an organic compound and this accomplishment is generally regarded as the beginning of organic chemistry."Sparrow "Milestones of Science" p.37. The discovery destroyed the vitalistic theory which held that organic compounds could be produced only by living organisms and led eventually to the brilliant results that have been achieved in attempts to synthesize other organic compounds.Dibner: Heralds of Science no. 45. - Sparrow: Milestones of Science no. 197. - Garrison & Morton no. 671.
