cure a Delirium not only In Six, Eight, or Ten Hours, 
but in One^ Two^ c» Three Minutes^ which is very afto- 
nifliing. 
If 1 had explain'd Vefication in general, you might 
have Teen, that the wounding Parrs might have reached 
their Stage in a quarter of an Hour ; and that is all I 
fuppofe, more than the Three Minutes, juft now affign'd. 
But how lhall we wound their Conveying Nerves , how 
fliall we apply a Blifter, that its Parts may afTeft, is now 
the great and only queftion that remains. To do this, 
you muft bring into your Memory, what you have feen 
in Diffeftions : That this eighth pair of Nervas, which 
ferves for the Heart's Contradion, has its rife from the 
Sides of the Medulla Ollongataht\{mA the Procerus An- 
nular is ^ by feveral Threads which joyn together, and 
go out by the fame hole that the Sinus Laterales dif- 
charge themfelves into ih& Jugulars. And fince the U- 
nion by the Atlas^ is not fo firm and compad as in the 
other Vertehm : it is evident, that there is no extraor- 
dinary hindrance, why fome of thefc wounding Parts 
may not come at that Nerve. But if you reflect again, 
that this Nerve, or confiderable Branches of it, run fu- 
perficially enough on the neck ^ and by conftquence, 
gives us Jefs difficulty to apprehend how fome of them 
are wounded^ and to underfland how thefe miraculous ef- 
fects do happen, and are produced. Or, it is eafy to 
unlieriland how the fmall parts of Cantharides can wound 
the eighth pair^ or by wounding its Branches derive from 
the Nerve it felf, and lefTen the Motion of its Liquor ; 
or 'tis not hard to apprehend how wounding by Cantha'^ 
rides hinders thQ difpojjtion of Separating Spirits, and in* 
iercepts them in their way to the Heart ; how they make 
its weaker Contraiiiony and a flower Pulfe. Or, again, it 
is evident, how the JmaU Emijfaries made in this way
