think proper you may tranfmit them to the Royal Society, by

§ L 
Dec. 25, 1787. Liquor produced by burning, in a clofe 
copper veflel, inflammable air got from iron by means of the 
Ream of water, and dephlogijiicated air , expelled by heat only, 
from minium. 
This liquor was blue, and contained a reddifh brown Pedi- 
ment. 
Exp. 1. Terra ponder of a lime water, 
2. Common lime water , and 
3. Caujlic fixed alkali , caufed a greenifh precipitation. 
4. Caujlic volatile alkali produced a beautiful deep blue 
precipitate, which was wholly re-difl'olved by the 
addition of more volatile alkali. 
5. Phlogifiicated alkali gave a reddifli brown precipitate, 
6. Nitre of lead , no change. 
7. Nitre of filver , a bluifh precipitate. 
8. Litmus , its colour firfl: turned red, then curdled, 
and at length nearly deftroyed. 
9. The filtering paper , employed to feparate the Pedi- 
ment, was a flow burning touch-paper. 
§ II- 
Dec. 30. Liquor produced, by burning in a clofe copper 
veflel, inflammable air , obtained as in § 1. and dephlogijiicated 
air , expelled by heat only, from manganese. This liquor 
was blue, and contained a reddifli-brown Pediment. 
Exp. 1 — 9. Similar to thofe in § 1. ; and the refults being 
.in all points the fame, I determined to mix the liquids toge- 
ther.
