CHAP. X. 

 Of the Staggers. 



FARRIERS, for the moft Part, term all or 

 moll Difeafes which afFed a Horfe's Head, 

 Stavers or Staggers ; and this Diforder in Human 

 Bodies, is called an Apoplexy., or Vertigo ; but 

 they are moftly the fame Thing, ( only a Vertigo 

 is an eafy Fit of an Apoplexy, ) by Reafon the felf- 

 fame Organs are aifedled ; and though the Vertigo 

 or Falling-Sicknefs in Human Bodies, does not al- 

 ways terminate in Death, yet ftill it is a flight Fit 

 of an Apoplexy, which I ihall defme after the Man- 

 ner following. 

 Apoplexy, The Word Apoplexy, is from the Greek 

 denned. a^oxAii t7<^, percutio, to ftrike ; becaufe a Crea- 

 ture is as it were fuddenly flruck with Death. It 

 is a fudden Deprivation of all Internal and External 

 Senfation, and of all Motion, unlefs of the Heart 

 and Thorax. For the underflanding of which, it 

 is neceffary to premife, Firjf, that if by any Means a 

 Nerve is tied, or comprefs'd, the Part to which 

 that NeiTe is diredled, lofes its Senfe and Motion. 

 Secondly^ that if any Nerve is cut, there difrils out 

 a Liquor. Thirdly, that Motion is performed, by 

 Reafon the Nervous Fluid is impelled by the Force 

 of the Arterial Blood, through the Nerves into .the 

 Mufcular Fibres. And lajily, that Senfation is from 

 hence, njiz. that Objedls comprefs or flrike upon 

 the Extremities of the Nerves by their Motion, 

 and drive back the Nervous Fluid towards the 

 Brain. 

 Apoplexy, An Apoplexy, therefore, is produced by any 

 its Courfe. Caufe which hinders fucli Undulation or wave-like 



Motion.
