it will be neceflliry to confider, that the Blood, examined 

 chymically, is found to confiil only of the following Prin- 

 ciples, VIZ. Volatile Salt and Spirit, fame Phlegm and 

 Sulphur, and a little Earth, but little or no fixed Salt. 

 Now every one, who is the leaft ac(|uainted with Chymi- 

 llry, muft be fenfible how many difteient forts of Liquors 

 may be form'd out of a few Principles varioufly combin'd 

 together : So that although the Blood itfelf fimply con- 

 lifts only of thefe above-mention'd, and to the Eye feems 

 only to be made up of its red and ferous Part j yet, ac- 

 cording to the lateft Obfervations, there are near thirty 

 feveral Liquors feparated from it ; all which is owing to 

 the various Strufture of the Glands, fome of which are fo 

 fmall, and fo varioufly wound up, and their Veilels drawn 

 out into fuch extraordinary Length, that Nothing but the 

 moft minute and fpirituous Particles of the Blood can pafs 

 through them ; and doubtlefs, of fuch a Strudure is the 

 cortical Part of the Brain, by which the Animal Spirits are 

 lecerned. Others again are more wide, and feparate chiefly 

 Excrements. But I fhall not enter upon this Subject, fee- 

 ing thofe who have any Curiofity that Way, m.ay be fully 

 fatisfied by perufing feveral Books thai have been profefled- 

 ly writ on that Subjecft.
