CHAP. XV. 

 Of the StaverSy or Staggers, 



TN order to the Knowledge of this Di- jp.^jex^ 

 ^ llemper, it will be necelTary firfl of all to ^'^' "■^' 

 .enquire into the Nature of an Apoplexy and Vertigo, for with- 

 out fome Infight into thefe, the other can nev er be rightly 

 underftood. 



Fir/t then, As to an Apoplexy^ That is ufually defin'd a 

 Privation of Senfe and Motion, excepting only a weak 

 and languid one in the Heart and Breaft ; and this pro- 

 ceeds either from a Caufe without the'Vedels, viz. when 

 the Blood or any other Fluid happens to break out of fome 

 Vellel within the Brain, or when there happens to be pre- 

 ternatural Bones or Tumours bred and contained within 

 the Skull, or any other extraneous Matter that may in any 

 Sort prefs upon the fcft Subllance of the Brain, caufing 

 thofe deadly Diforders. But this is a Species that is in- 

 curable, and for the moft Part feizes fuddenly, without 

 3ny foregoing Tokens and Warnings : But the other pro- 

 ceeds from fome Caufe within the Vefiels, whereby the 

 Arteries, which are woven into the Pia Matei\ or inner- 

 moft Membrane of the Brain, or that Part of it which in- 

 volves the Trunk of all the Nerves, becoraes over-much 

 extended ; fo that by the Preilure of thefe VeHels upon 

 them, Senfation is intercepted, and Motion loft. 



Thus, in an Apoplexy., Senfe and Motion are in a Man- 

 ner quite loft, becaufe of the Preffure that is made upon the 

 Origin of all the Nerves that arife from the y . 

 Head : But in a Vertigo, Objects that are ^^ ^'^^" 

 at Reft, appears as if they were turning round, and by that 

 Means occafion any Creature to reel and ftagger: And this 

 proceeds from the Vibrations and Tremors of the Optick 

 Nerve, whereby the Images falling not directly, but fuccef- 

 fively upon the different Rir:s of the R.eti?ia, an Objeft that 

 is at Reft, will therefore appear as if it v/as turning round ;
