EXPERIMENT I.
HAving caused twelve Ounces of dryed Blood to be carefully distilled, the Sub∣stances obtained from it, were of Volatile Salt and Spirit together five Ounces; the Liquor poured off from the wet Salt being thirteen Drachms, fifty four Grains, so that the Salt was three Ounces, two Drachms, and six Grains; of fetid Oyl there were two Ounces; of Caput Mortuum four Ounces, and two Drachms; so that about six Drachms of the whole was consumed in the Operation. The Caput Mortuum being calcined yielded but six Drachms and a half of ashes, the fixed Olea∣ginous Parts being consumed by the accensi∣on; the colour of the ashes was reddish when cool, tho' in the fire they appeared white as soon as the Oyl was consumed, these ashes be∣ing turned into a Lixivium, afforded five scru∣ples of white fixed Salt, besides a little which got into the contiguous Sand, which being recovered by Water, and reduced to a Salt made a scruple more. So that there remain∣ed for the Terra Damnata fourteen Scruples and a half, which is a good deal above twice
