|
 |
(1773-07-19): Records decrease in weight of ammonia on the addition of lime (perhaps has confused ammonia with carbon dioxide). Performed with hydrometer.
|
|
|
(1773-07-20): Combustion of phosphorous. Experiment described in the Opuscules. "Il y a diminution de volume de l'air pendant la combustion du phosphore et je l'ai attribuée jusqu'ici à la fixation de ce même air, mais ne pourrait-il pas arriver que ce fu
|
|
|
(1773-07-22): Combination of water with the air in which he has burned phosphorous. Asks if decrease in volume might not be due to humidity of air.
|
|
|
(1773-07-22): Precipitation of "terre calcaire" (dissolved in nitric acid) by adding alkali volatile concret-caustique
|
|
|
(1773-07-22): Reduction of the calx of mercury precipitated by chalk. "L'air s'est dilaté comme à l'ordinaire mais sur la fin l'eau est remontée sensibliment." Formation of a little liquid mercury. No precise conclusion.
|
|
|
(1773-07-26): Nitric acid, varying degrees of acidity; amount of lime necessary to neutralize. Experiments on fixed air. Density of water solutions with hydrometer. Mixes water solution of fixed air with limewater
|
|
|
(1773-07-31): Reduction of lead calx by charcoal. Proportion of lead in minium; examination of the air resulting from the reduction. Rat placed in the gas. No results given.
|
|
|
(1773-08): Experiments involving fixed air and ammonia which he may well have confused.
|
|
|
(1773-08-05) (1773-08-14): Experimentation with the burning glass
|
|
|
(1773-08-07): At the Académie: "M. Lavoisier a demandé des commissaires pour examiner un traité sur l'air fixe qu'il veut publier." Commissioners: Cadet and Le Roy. Concerns the Opuscules.
P-V, 1773, 172.

P-V, 1773, 11 August.
|
|
|
(1773-09-25) (1773-09-29): Verification of Lavoisier's experiments by commissioners. Lavoisier performs them in presence of Trudaine, Le Roy, Montigny, Macquer and Cadet.
BNF Nuov. Acq. 5153.
|
|
|
(1773-09-29): Identifies gas produced by burning charcoal as fixed air (limewater test)
|
|
|
(1773-10): Publication in the Observations sur la physique of the Précis de la doctrine de M. de Morveau, sur le phlogistique; et Observations sur cette doctrine (anonymous).
|
|
|
(1773-10): Calcination of diamonds and charcoal with the burning glass. Calcination of charcoal in iron flasks and tubes; finds that rust of the iron instruments is reduced by charcoal.
|
|
|
(1773-10): Calcination of lead over mercury with a burning glass. A candle is extinguished in the residual gas
|
|
|
(1773-10-22): Experiment on diamond. Heated with burning glass in atmosphere of fixed air.
|
|
|
(1773-10-29): Reduction of minium by charcoal in an iron tube. The residual gas is saved from October 29 1773 to May 27, 1774. It asphyxiates a bird, extinguishes a candle.
|
|
|
(1773-11-13): Reactions of phosphoric acid and of its salts of calcium (chaux), magnesium etc. Degree of affinity of phosphoric acid: it is displaced from its salts by sulphuric acid and nitric acid.
|
|
|
(1773-11-13): A the Académie: "M. Lavoisier a lu un mémoire sur la combustion du diamant". Probably refers to experiments performed Aug. 5-14, 1773, with lens of the count de la Tour d'Auvergne and the little lens of the Académie.
