| Title | Paper, 'An experiment made before the President and fellows of the Royal Society in which a surprizeing change of color from a pale transparent or clear liquor to a very blew ceruleous one was exhibited, and that in an instant, by the admission of aire only: applyd to illustrate some changes of colour, and other effects on the blood of respiring animals' by Fr [Frederick] Slare |
| Date | [1693] |
| Description | Slare describes an experiment in which copper filings are mixed with sal ammoniac to produce first a clear liquid, and then a deep blue liquid when air is removed and then reintroduced to the mixture. Slare compares this colour change to the colour change that occurs when blood is exposed to air from a vein or when it undergoes respiration through the lungs.
