Afligns diftind Virtues. Particularly , the LightWaters 
he appropriates to Obftruftionsof the more remoteand 
finer PalTages of the Glands, &c. and the Heavy Acid 
to the Aftringing and (lopping Fluxes of Blood,- in 
the Virtues of the laft the Author confiders the Apo- 
plexy diftindly, which he makes to proceed from a 
Vice of the Glandular Duds, and not from any Obfiru- 
dlion in the Blood- VelTels ; eviocing^^j he thinks, that no 
Obftrudion of them, or of the Brain, nor compreflion of 
the Brain can efFed; it 5 and correds the Notion of 
the continued Courfe of the Animal Spirits, to be the 
continuer or our Machin ; but the fpring of the Brain 
correfpondent to and kept up by the Air, which he 
makes the ufe of Refpiration , and which he argues 
to be deltroyed in this Difeafe, by admifTion of Air with 
the Blood which breaks in, and that this Diftemper is 
Cured by thefe Waters on that fcore ^ what concurs to 
the Produftion of this Difeafe (which is to be regarded) 
whence it becomes fo frequent ; this he makes to be

fufEciently evince: Firil from a general Courieof the Dif- 
eafes of the lafl Years, in which he proves die Caufe to 
be the fame ; and then chiefly, that upon the removing 
of the Matter from the Brain, it appears in rheuraatick 
flatulent Tumors in the part where it fettks, and which 
readily return to produce another fit : in all which he 
approves Dr. ufe of the Glandular Secretion, and
