in order to determine both the Matter and Form of 
this Ferment, he lays down fbme obvious Conditions of 
it ; of which though (ome may agree to one, (bme to 
another of the enumerated Hypothefes,yet he endeavours 
to fhew, that All will not agree to any one of them, 
^nd therefore thinks fuch a one is to be fearched for, to 
which they eahly will. 
His own Opinion therefore is, That the Cortical part 
of the Brain may be the primary Seat of this Febrile 
Ferment and that the Liquor to be there feparated, be- 
coming disproportionate to the Animal Functions, is the 
Minera of it ; and, being thence difpenfed into all parts 
of the Syftema Nervorum^ may by degrees rife to fuch a 
Maturation as may produce the Fits. 
Here he takes occafion to endeavour to eftablilh the 
Exiftence of the Nervous Juyce, in confirmation of what 
he had heretofore delivered, and indeed (for a main Ar- 
gument to evinceit^X to revive and farther make out, 
by a fomewhat long D^du£tion, the Opinion of Dr. Ent, 
Glijfon, &c. That we are not only dire&ively, but ma- 
terially nouriilied by that Juice; for a particular Ac- 
count of which we refer to the Author. 
To this Notion of his, he endeavours to {hew, that 
thealledged Conditions all agree ; which done, he lays 
down his Hypothecs of the manner of the Production of 
the Paroxyfme minutely • fuppofing, that fome Incon- 
gruous, though at firft inoffenfive, matter (on the fcore 
of ProcatarftickC&ufcshe points at) being admitted in- 
to thePtootsof the -Nerves in the Cortical part of the 
Brain, is from them propelled into the Medullary, and 
thence into the Tracfts of the Nerves and Fibres (which 
he takes to be but Propagines Nervorum j of the whole 
Body ; in which moving (lowly, it by degrees maturates 
into a Fermentative Sulftance, and acquires an Acrimony : 
With which when they are filled, and the Acrimony be- 
comes troubkfome, they contr?-^ themfelves to expel 
it,
