|
(1781-11-16): Study of vaporisation of ether. The vaporisation is carried out over heated mercury; the drop in temperature of mercury is measured.

(1781-12): Solution of iron in nitric acid. Collects the nitrous air, precipitates the iron; crystallisation of salpêtre.

|
|
(1781-12): Experiment on heated iron. Heats the iron alon in a retort, no results; he heats steels, obtains an inflammable air which burns a blue flame (carbon monoxide). Following this, dissolution of iron in nitric acid.
