Markham basin his Catalogue enumerated allthoie Dif- 

 eafes that are peculiar to Man, but in Horfes they are very- 

 hard to be diftinguifh'd, becaufe of the Similitude of the 

 common Symptoms ; neither has the Sieur de Solleyjell 

 mended the Matter very much, having confufedly fcaiter'd 

 them here and there in his Writings, excepting only that he 

 has clailed fome together vs'hich were the Concomitants of a 

 great Sicknefs that happened in Frame and Gsrmany in his 

 Time; but thefe were improperly tcrm'd Difeafes of the 

 Head, being only the Attendants of that Sicknefs. We 

 fhall therefore go on a little more methodically in explain- 

 ing thofe Diforders, as they feem moft agreeable to the 

 State and Condition of that Animal ; and that we may 

 avoid all ufelefs Divifions, we fhall take them in the Method 

 "^hich feems to be the moft natural.

 being the Concomitant of fome other Difeafe : But our 

 Bufinefs here is only with the firft Kind, fince the other is 

 but a Symptom, which muft of courfe wear off with the 

 Pifesfe to which it belongs. 



As to the Caufe, it is believed to proceed from a Di- 

 ftraftion of the Fibres of fome Blood-veflels in the Brain, 

 or Membranes thereof, occafioned by fome of the fmalleit 

 t*ar tides of the ^erum being ftruck into the Ports or Inter- 

 ilices of the faid Veflels, by the frequent Occurfions of the 

 Blood. 



The Signs are, according to Markham^ the hanging 

 (down of the Horl'e's Head and Ears, dropping of his Urine, 

 dimnefs of Sight, fwoln , waterifh Eyes : But thefe are 

 common to divers other Difeafes ; and I am truly of Opi- 

 nion, fuch a Head-ach cannot be eafily diftinguifh'd in brute 

 Creatures, that want the Faculty of Speech, and therefore 

 cannot declare their Infirmities : But however^ if a Horfe
