Berthollet (Essai de statique chimique, 1803) expressly controverted them.
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.
Statique (1890), vol.

Poinsot's earliest work was his Elemens de statique (1803; 9th edition, 1848), in which he introduces the idea of statical couples and investigates their properties.

Berthollet's most remarkable contribution to chemistry was his Essai de statique chimique (1803), the first systematic attempt to grapple with the problems of chemical physics.
Plateau (Statique experimentale et theorique des liquides), who made elaborate study of the phenomena of surfacetension, adopted the following method of getting rid of the effects of gravity.
