and this may be occafion'd, either when an Animal is fear- 

 ful of falling, or from a Repletion and Overfulnefs of thofe 

 Arteries which are fituated near the Optick Nerve, which, 

 by prefling upon the Brain, will caufe a Shaking in that 

 Nerve. But our Bufmefs is only with the laft. 

 -.. ^ Now if we examine a little carefully into 



reduciblfu)^ all the different Appearances of that Diftem- 

 the one or the per which Farriers call the St avers or Stag- 

 other, pronPH by gers^ wc fhall find them reducible to one of 

 Infiances taken thefe IMaladies above defcribed. 

 from the vari- For, firft ofallj if we confider that Sort 

 cus Appearances which is the moft fimple, viz, when a 

 of that Difeafe. j^grfe fuddenly falls down upon the Road 

 in a very hot Day, or when he falls upon hard Ri- 

 ding, we fhall find nothing in the Caufe of this Diforder, 

 but what is in one of the former ; and the Reafon of this 

 is eafy enough to be conceived, and will happen to a 

 Horfe, whether he be in a good or bad Cafe ; for when the 

 Blood is put into a more than ordinary Motion by any 

 hard Exercife, it will ealily flow into the Brain of a Horle 

 in a greater quantity, than can be readily returned by the 

 Veins ; and therefore the Origin of the Nerves will be 

 prefs'd upon by the diftending VeJlels, fo as to intercept the 

 Animal Juices ; or otherwife thefe may be fent forth in 

 fuch diforderly Manner, as to occafion a Horfe's falling 

 down ; but in this Kind, when a Horfe has lain fome lit- 

 tle Space, and that the Impulfe of the Blood ceafes, it 

 then flows more regularly through the Veins, by which the 

 Arteries become lefs diftended, and the Horfe recovers his 

 fienfes, and rifes up as from Sleep. Thus the Head is 

 afFedfed in the fame Manner as in an Apoplexy ; but as there 

 is little or no Fault fuppofed to be in the Blood, the Horfe 

 foon recovers, and oftentimes without the Afliltance of any 

 Application. 



There is another Kind of Staggers which refembles the 

 former, and alfoafieds the Head in the fame Manner as an 

 Apopledick Diforder, and that is when a Horfe falls down 

 while at Grafs : And this Sort I have obferv'd happen the 

 firft or fecond Day after they were turn'd out ; for while 

 they feed with a more than ordinary Intenfenefs, with their 

 Head conftanily down towards the Ground, the Blood 

 muft flow in a more than ordinary quantity to the Brain ; 

 and Vvliile the Head is in this dependent Situation, the 

 Uiood i;i iis Return mull afcend upwards : So that if a 



Horfe's
