(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

|
(1774-11): 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.
