Farther, I drew fome blood from my finger, and mixed it with 

 different pails of the water wherein was that lixed fait, and I ob- 

 ferved, that the globules of blood from whence its rednefs pro- 

 ceeds, appeared as if their moili parts had been extracted by heat, 

 for each globule appeared of a ditFerent - lliape, fonie dat, and I 

 could fee that they were compofed of fmaller globules ; others 

 looked like dead animalcules, whofe feet difplayed themfelves, and 

 in a word, fo many different figures, that I cannot rehearfe 

 them all. 



After this, I took ibme water wherein the volatile fait was dif- 

 folved, and mixed it alio with fome blood, and I immediately per- 

 ceived many of the globules of blood to be fo altered or diflblved, 

 that they could not be dillinguillied without great attention, fome 

 of them preferving their figure longer than others ; but this ap- 

 pearance I did not perceive, unlefs w here a very little blood was 

 mixed with much water. 



Another of thefe Stones, in weight equal to about the twenty- 

 ninth part of a pound, I applied to a very llrong fire, and obferved 

 the volatile fait, which proceeded from it, remained fluid fo long as 

 it continued warm ; but when I took the black burnt part of it, it 

 lay divided in many fcaly parts like the coats of an onion, and that 

 part which was not fo divided, was the internal part of the Stone, 

 which preferved its round fhape, and was not larger than the head 

 of a large pin. This burnt fubfiance, or caput mortuum, I weighed, 

 and found it contained ten parts of a pound, fo that nineteen parts, 

 confilVmg of fait and oil, had been driven out of this Stone ; and 

 when I poured water on the refidue, and fuffered it to evaporate, 1 

 found, upon weighing, that it was reduced to eight parts. While 

 the fait and oil I had extracted remained warm, I colledled a fmall 

 portion of them, and faw that the oil, which was of a yellowifli 

 colour, by reafon of the great number of faliue particles in it, was 

 not fluid.
