EXPERIMENT II.
A parcel of Blood weighing ten Ounces and seventy three Grains, being slowly distilled to dryness in a Head and Body on a digestive Furnace, afforded of Phlegmatick Liquor seven Ounces, two Drachms, and forty seven Grains; and of Caput Mortuum or dry Substance two Ounces, two Drachms. This pulverable mat∣ter being distilled in a Retort by degrees of fire yielded two Drachms, forty eight Grains of Oyl. The Spirit being poured off, the Salt weighed but forty eight Grains, and the Salt being washed out with the distilled Water, we obtained thence by Sublimation into the neck of a Glass-Egg one Drachm, five Grains of dry Salt. The Caput Mortuum weighed six Drachms, twelve Grains, which being carefully calcined yielded two Scruples and four Grains of ashes; which were red, and these being elixivated afforded eighteen Grains of Salt, besides the remaining Earth, which is of a red colour with an Eye of Pur∣ple,
