|
|
(1786-04-03): Determination of the density of nitrogen. Followed by notes on similar determination for atmospheric air (1 March 1764, March and April 1785) and for oxygen (27 July 1785).
|
|
|
(1786-06-22): Experiments on the formation of nitric acid. Continuation of the experiments of October 1785; brings oxygen and nitrous air into contact in an "eudiomètre hydrostatique."
|
|
|
(1786-08-06) (1786-09-15): Study of the germination of garden gress seeds under vacuum, in oxygen and in nitrogen. Examination of gases liberated.
|
|
|
(1786-09-16): Experiments on alcoholic fermentation. Addition of barm (levure de bière) to a sugar solution; the fixed air evolved in absorbed by solution of alkali. Similar experiments the 27 April and 5 June 1787.
|
|
|
(1786-09-20) (1786-09-29): At the Arsenal: experiments on a new combustible proposed by M. le Prieur du Temple are carried out by members of the committee on agriculture, the Régisseurs de poudres and representatives of the Académie.

(1786-11-09): Gold dissolved in aqua regia; weights and measures. Continued February 20, 1787.
|
|
1787 |
|
|
(1787-01-05): New experiment on the heat of formation of water. The laboratory notebook says 5 January 1786, but it is surely 1787. Prepared the 5th, the experiment is done the 13th and repeated the 16th.
|
|
|
(1787-02-20): Experiments on yeast; followed on May 4 by analysis by distillation. Prelude to further studies on alcoholic fermentation.

|
|
|
(1787-06-05) (1787-06-12): Series of studies on fermentation. Analysis of fermented liquor, distillation of the alchool.
|
|
|
(1787-06-06): Action of sulphuric acid on sugar. Acid diluted by half; heating. Carbonization of sugar, attempt of analysis of residue.
|
|
|
(1787-06-22) (1787-07-19): Analysis of sugar by distillation. Obtains an acid which upon treatment (oxidation) with nitric acid gives oxalic acid.
|
|
|
(1787-07-27): Combustion of ether and of alcohol in a lamp fed by vital air, under a bell jar over mercury. Measurement of quantity of fixed air produced.
