lavoisier's Usage Examples:

Lavoisier appears to have assumed that the composition of every chemical compound was constant, and the same opinion was the basis of much experimental inquiry at the hands of Joseph Louis Proust during 1801 to 1809, who vigorously combated the doctrine of Claude Louis Berthollet (Essai de statique chimique, 1803), viz.

By his insistence upon the use of the balance as a quantitative check upon the masses involved in all chemical reactions, Lavoisier was enabled to establish by his own investigations and the results achieved by others the principle now known as the " conservation of mass."

The theory advocated by Lavoisier came to displace the phlogistic conception; but at first its acceptance was slow.

Lavoisier may be justly regarded as the founder of modern or quantitative chemistry.

To quote Antoine Laurent Lavoisier, " ...

At one time, indeed, he found Lavoisier's views so specious that he was much inclined to accept them, but he overcame this wavering, and so late as 1800 he wrote to the Rev. Theophilus Lindsey (1723-1808), "I have well considered all that my opponents have advanced and feel perfectly confident of the ground I stand upon....

His next and most important publication was his famous paper "On the Equilibrium of Heterogeneous Substances" (in two parts, 1876 and 1878), which, it has been said, founded a new department of chemical science that is becoming comparable in importance to that created by Lavoisier.

He also contemplated a thorough-going reform of the ferme generale, but contented himself, as a beginning, with imposing certain conditions on the leases as they were renewed - such as a more efficient personnel, and the abolition for the future of the abuse of the croupes (the name given to a class of pensions), a reform which Terray had shirked on finding how many persons in high places were interested in them, and annulling certain leases, such as those of the manufacture of gunpowder and the administration of the messageries, the former of which was handed over to a company with the scientist Lavoisier as one of its advisers, and the latter superseded by a quicker and more comfortable service of diligences which were nicknamed" turgotines."He also prepared a regular budget.

Lavoisier was the first investigator to study fermentation from a quantitative standpoint.

Lavoisier adequately recognized and acknowledged how much he owed to the researches of others; to himself is due the co-ordination of these researches, and the welding of his results into a doctrine to which the phlogistic theory ultimately succumbed.
