This knowledge, joined to what he had gathered by historical reading of equally unusual extent, he carefully digested and gave to the world in his Biographisch-literarisches Handworterbuch zur Geschichte der exacten Wissenschaften, containing notices of the lives and labours of mathematicians, astronomers, physicists, and chemists, of all peoples and all ages.
It is remarkable that this theory should have gained the esteem of the notable chemists who flourished in the 18th century.
He proceeds to give what has been quoted as his first table of atomic weights, but on p. 248 of his laboratory notebooks for 1802-1804, under the date 6th of September 1803, there is an earlier one in which he sets forth the relative weights of the ultimate atoms of a number of substances, derived from analysis of water, ammonia, carbon-dioxide, &c. by chemists of the time.
Chemists also had to thank him for translating three editions of the Lehrbuch of Berzelius and all the successive volumes of the Jahresbericht into German from the original Swedish.
This revival of the synthetical production of S03, at a period when this article had suddenly become of great importance, caused the greatest excitement among chemists and led to numerous attempts in the same direction, some of which were at once sufficiently successful to compete with the Bohemian process.
Always keenly alive to the interests of chemists in general, Bell conceived the idea of a society which should at once protect the interests of the trade, and improve its status, and at a public meeting held on the 15th of April 1841, it was resolved to found the Pharmaceutical Society of Great Britain.

Up to about this time Lavoisier's work, mainly quantitative in character, had appealed most strongly to physicists, but it now began to win conviction from chemists also.
Klaproth and the German Academy, and by most English chemists except Cavendish, who rather suspended his judgment, and Priestley, who stubbornly clung to the opposite view.
Examinations are suited in the first instance for the purpose for which they were originally designed in medieval universities - the test of technical and professional capacity; it has never been proposed to abolish qualifying examinations for doctors, pharmaceutical chemists, &c.; the tests applied are (or should be) direct tests of capacity carried out under conditions as nearly as possible like those of actual practice.
Usually this lime is regarded only as mechanically mixed with the bleaching-compound, CaOCl 2, but some chemists adopt formulae in which this lime is equally represented.

He had now secured a leading if not the foremost place among the chemists of the French capital, and the demand for his services as adviser in technical problems and matters of practical interest made great inroads on his available time.
The manufacture of synthetic indigo by German chemists has greatly affected the growth and manufacture of indigo, the indigo factories decreasing in1904-1905from 402 to 252.
The theory of the ionization of salts in solution has raised much discussion amongst chemists, but the general fact is certain that electricity only moves through liquids in association with matter, and simultaneously involves chemical dissociation of molecular groups.
The publication of his great Dictionnaire de chimie pure et appliquee, in which he was assisted by many other French chemists, was begun in 1869 and finished in 1878; two supplementary volumes were issued 1880-1886, and in 1892 the publication of a second supplement was begun.
The two great Swedish chemists, Torbern Olof Bergman (1735-1784) and Karl Vilhelm Scheele (1742-1786), flourished at this time.
The governors were directed to regulate religious instruction in secular schools, to prevent horse-stealing, to control subscriptions collected for the holy places in Palestine, to regulate the advertisements of medicines and the printing on cigarette papers, to examine the quality of quinine soap and overlook the cosmetics and other toilet articles - such as soap, starch, brillantine, tooth-brushes and insect-powder - provided by chemists.
That substance, recently discovered in Paris, was attracting the attention of French chemists when he stepped in and, after a short examination with his portable chemical laboratory, detected its resemblance to chlorine and pronounced it an "undecompounded body."
The chemists and bacteriologists do not appear to have finally determined the true nature and origin of this growth, but it is found in the impounded waters, and passes into the pipes, where it rapidly increases.
In 1906 Lunge (in a paper published with Bert) to some extent modified his views, by introducing an intermediate compound, sulphonitronic acid, SO 5 NH 2, which had been noticed by various chemists for some time through its property of imparting a deep blue colour to sulphuric acid.

Rather before the commencement of the 19th century the work of Lavoisier had rendered it very probable that chemical changes are not accompanied by any change in weight, and this principle of the conservation of matter was becoming universally accepted; chemists were also acquiring considerable skill in chemical analysis, that is, in the determination of the nature and relative amounts of the elements contained in compounds.
The superiority of this notation over that of Dalton is not so obvious when we consider such simple cases as the above, but chemists are now acquainted with very complex molecules containing numerous atoms; cane sugar, for example, has the formula C 12 H 22 0, 1.
Some distinguished chemists have thought atomic that this fate may be awaiting the atomic theory, and that in future chemists may be able to obtain all the guidance they need from the science of the transformations of energy.
In this respect his hypothesis has much in common with the " law of mass-action " developed at a much later date b y the Swedish chemists Guldberg and Waage, and the American, Willard Gibbs (see Chemical Action).
In addition to empirical and molecular formulae, chemists are in the habit of employing various kinds of rational formulae, called structural, constitutional or graphic formulae, &c., which not only express the molecular composition of the compounds to which they apply, but also embody certain assumptions as to the manner in which the constituent atoms are arranged, and convey more or less information with regard to the nature of the compound itself, viz.
It is not to be supposed that there are any actual bonds of union between the atoms; graphic formulae such as these merely express the hypothesis that certain of the atoms in a compound come directly within the sphere of attraction of certain other atoms, and only indirectly within the sphere of attraction of others, - an hypothesis to which chemists are led by observing that it is often possible to separate a group of elements from a compound, and to displace it by other elements or groups of elements.
Berzelius immediately appreciated the importance of this discovery, notwithstanding 1 The reader is specially referred to the articles Alizarin; Indigo; Purin and Terpenes for illustrations of the manner in which chemists have artificially prepared important animal and vegetable products.
