He concluded the law of conservation of mass “mass is neither created nor destroyed”. He then placed a small plant in the jar and noticed the the mouse regained consciousness. As such he merits a special place in the history of respiratory physiology. Standard oxygen is colorless, tasteless, and has no odor.

Priestley moved to America seeking religious and political freedom. Priestley gave his discovery the name oxygen. How much oxygen, O2, is produced by the decomposition of 25 g of HgO? He is usually credited with the discovery of oxygen, having isolated it in its gaseous state, although Carl Wilhelm Scheele and Antoine Lavoisier also have a claim to the discovery. Carl W. Scheele had also discovered oxygen in Sweden in 1771, but his account had gone unpublished until 1777. Dr Glynn Skerratt and Dr Helen Cooke ECG Committee glynn@skerratt.com ECG Bulletin January 2020.
