 |
(1774-03): Beginning experiments on the reduction of iron oxide. He refers to it in the memoir of the nature of the principle which combines with metals.
|
|
|
(1774-03-23) (1774-06): Preparation of nitrous ether. Study of the air released from nitrous ether. Research on nitrous air (NO); detonation of nitre, study of the gases released.
|
|
|
(1774-07-28): Brisson, Lavoisier, Baumé and Cadet meet at Brisson's place to verify le comte de Milly's experiments on reduction of metallic calces by means of the electric fluid. On this occasion Baumé presents a sample of mercury precipitate per se whic

|
(1774-09-30): Letter of Scheele to Lavoisier, describing action of heat on silver carbonate and the air obtained.
|
|
|
(1774-10-05) (1774-10-15): Experiments with the large burning glass of Mr. Trudaine, generally to test the effectiveness of that lens.
|
|
|
(1774-10-28): Experiments at Montigny. Preparation of "air marin" (HCl), air alcalin (NH3) and air nitreux (NO).
|
|
|
(1774-10-28): Passes a spark between the end of an iron wire and a mercury surface in a closed tube containing air, in the presence of litums dye. The litums turns pink. In a vacuum, discharge continues for fifteen minutes, no coloration. In the presence
|
|
|
(1774-11): Beginning of experiments on the reduction and decomposition of precipitate per se with a burning lens. There is no trace of this work to be found in the laboratory notebooks which we possess.
|
|
|
(1774-11-22): Calcination of lead in a closed retort. The residual air extinguishes flames; with limewater gives a precipitate but the test is not conclusive; shows no reaction with nitrous air.
|
|
|
(1774-11-29): Solution of iron in nitric acid; quantity of air released.
|
|
|
(1774-11-29): First notes on vegetable analysis. Distillation of vegetables gives water, acid, oil and charcoal but the composition is not known. Asks what is the nature of the air released and of the oil formed. "Pour l'article de l'huile, on pourrait en

|
|
(1775): List of experiments. The tenth item reads "revivication du mercure précipté per se."
|
|
|
(1775-02-28): Experiments at Montigny on fictitious airs. Experiment to test the similarity of the inflammable vapor of alcohol and ether with the "air inflammable" produced by the action of vitriolic acid and copper.
|
|
|
(1775-03): Experiments on the behavoir of fixed alkali with charcoal to see if carbon facilitates the separation of fixed air.
|
|
|
(1775-03): Action of fuming nitric acid on sulphur; study of the gas released. "Le gaz fermentait … avec l'air commun."
|
|
|
(1775-03): "Air sulfureux volatil" from reaction of charcoal and vitriolic acid; no gas produced from reaction of "spath calcaire" and charcoal.
|
|
|
(1775-03): Lavoisier is seeking new gases in reaction where fumes are produced: nitrous air from minum; fuming liquor of Libavius; "air aceteux" from crystals of Venus and from fuming liquor of Boyle.
|
|
|
(1775-03-31): Experiments on mercury repeated in presence of La Rochefoucauld, Trudaine de Montigny, Macquer and Cadet. (Observations sur la physique, 1775, vol. 5, p. 429).
|
|
|
(1775-04): Experiment on heating chalk with charcoal and on reduction of iron oxides.
|
|
|
(1775-04): Experiment on sample of traprock (metamorphosed volcanic rock) brought by the duc of La Rochefoucauld; fusion with borax and salt.
|
|
|
(1775-04): Experiment on iron oxide (reduction?) made in Lavoisier's furnace by Guyton de Morveau.
|
|
|
(1775-04-08): Experiments with La Rochefoucauld, Macquer, Cadet, Desmarets and Le Roy. Minium and sel ammoniac; vapor and air do not support combustion, nor precipitate limewater.
|
|
|
(1775-04-08): Experiments on inflammable air, burning it in fixed air and in air enclosed vessels. Notes that it burns only in proportion to the air introduced. Asks what remains when completely burned.
|
|
|
(1775-09): Begins work on saltpetre. Analysis of "cendres salpetriers" and "cendres de tourbe" (peat ash)
|
|
|
(1775-09-26): Mother liquor of nitre - its decomposition by potash.
