(1774-02-05) (1774-02-15): Calcination of tin and lead in a closed vessel, no gain in weight; upon admission of air gain of weight equal to that of metal.
(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
