1010 ; 
confequently the weight of the dry’d is 
only two fifteenths of the Blocd* 
But for farther fatisfadion, an Analyfis was made 
at ,my defire with a large quantity of Blood, amount- 
inn to four Pounds fcuitcen Ounces, by that ingeni- 
ous and skilfull C hymiit, Mr. John Brown. 
From tills was obtain’d, with a very gentle heat, two 
Pounds, fourteen Ounces , and fix Drachms of a 
Phlegmatick Liquor, that had fcarce any thing of the 
fetid Scent, which is ufual in the difiilJation of Ani- 
mal Subftances; and its Specifick Gravity was nearly 
the fame with that of common Water, being but 
I oo, 8. This being mixt with a (trong folution of 
Alum, fcarce a.Torc’cd zny Coagultim but exhibited a 
confiderable one upon mixture with a folution of Ro» 
man Vitriol. 
The difiillation being continued with the fame 
Hear, we had feven Ounces more of Phlegm confide- 
rably impregnated with Volatile Salt, as was manifefl: 
from the Smell. The Specifick Gravity of this was 
1007, and having mix’d it. with Tindiura Martis opi- 
ma. Solution of Alum, and of Roman ViinoX,' a large 
Coagulum was precipitated. In diflilling thefe there 
was loft by Evaporation, two Ounces and two Drachms. 
The third portion of Liquor, being rais’d with a 
ftronger Fire, amounted to feven Ounces fix Drachms. 
This was reddifti, and turbid, and to ftrongly charg’d 
with Volatile Saits, that it might very well defer ve 
the name of Spifir. Its Specifick Gravity was »o8o, i. 
Befides thefe we had feven Drachms of Volatile 
Salt, an ounce of Oil, and eight Ounces four Drachms 
of Cafut Mortuum, which ftill retain’d fome fraall re- 
mainder of the Oil, as was manifefl: from its taking 
Fire at the flame of a Candle. In this latter part of 
the Operation was loft three Ounces, feven Drachms.
