not from the Corruption of the Humours • tho he de- 
nies not that the Indications arifing from the Corrupti- 
on of the Humours may alfo have their ufe. 
In order to eftablifti his Hypothecs, he demonftrates 
the following Lemmas, That there are really fuch things 
as Animal Spirits, where he enumerates all their known 
Properties : That fome of thefe Spirits are contained in 
-every minute Fibre : That they flow from the Brain as 
Rays from the Sun, and that the Brain is as it were their 
great Cittern, and the Nerves the Pipes by which they 
are convey 'd to the other parts : That they are the firft 
Principle of Adion, and do in divers manners agitate 
and operate upon the Humours : That they are inti- 
mately united to the Blood ; and here he takes occafion 
-to prove by many Arguments, That the Blood in its 
Circulation pafles through the Habit of the Body be-

Veins : That thefe Spirits may be feveral ways vitiated, 
without any antecedent Corruption of the Humours ; 
and tho the "Blood out of which the Spirits are made

feale can't be faid to be begun till the Spirits are infedted : 
That the Blood and Humours are alter'd and corrupted 
by the Difeafes of the Spirits, which he proves by feve- 
ral remarkable Itiftances, and (hews how a Diftemper in 
a particular part, as Confumption, &c. becomes an 
univerfal Difeafe. Then he proves by many cogent Ar- 
guments, that ail univerfal Difeafes, whether primarily 
ftich, or occafion'd by the difaffe&ion of a particular 
part, do immediately arife from the Spirits, and that 
the Sympathy of one part with another, and the Tran- 
flation of a Diftafe from one part to another can't other- 
wife be explained, and that fome peculiar Dyfcraiy's of 
the Spirits are the Caufes of the Diftempers even of 
particular parts, and that the Specifics us'd in their Cure 
have
