in 48 or 72 Hours (which conftitutes the Intervals in Ter- 

 tians and Quartans) therefore the Blood will probably in 

 that Time acquire a Degree of Vifcidity equal to what it 

 had before the Beginning of that Spaccj that is, immediate- 

 ly before the Solution of the proceeding Fit, and therefore 

 another Fit will be apt to return at the fame Diflance of 

 Time. But if any Alteration happens, whereby the Sto- 

 mach may be render'd yet more weak ; or if a Food of 

 harder Digeftion than what is ufual happens to be eat in 

 that Time ; or if the common Dilcharges happen to be 

 more than ordinary oblbuded ; or if a more than ordi- 

 nary Quantity of the thinner Parts of the Blood be exhauft- 

 ed J then the Fits, will, probably, return ol'tner, by reafon 

 the fame Degree of Vifpidity will be fooner ingender'd in 

 the Blood. But if between the Intervals, the Stomach ga- 

 thers more Strength, and the Blood becomes more attenua- 

 ted and thin, whether thofe Changes happen by the Ui'e 

 of proper Exercile, Diet, or Phyfick, then the Fit will not 

 return at its ufual Time, but, if at all, its Return will be 

 later, for the Reafons already alledg'd j and if the fame 

 Oeconomy of Diet and Phyfick be continued, the Blood 

 muft yet become more attenuated, and the Stomach will 

 acquire its wonted Tone ; fo that of Confequence there 

 will be no farther Return of the Diieafe. 



From all which it is evident, that the Cure of Intermit- 

 tent Fevers conlilt not in thofe Things that are necellary 

 barely to remove the Fit, for that happens naturally by a 

 determin'd Increafe of the Quantity of vifcid Blood, di- 

 rtending the fmall Veflels, and an habitual Aptitude in the 

 lUdorifick Pores, to calt off the Lentor by Sweat ; but that 

 Aptitude conilitutes Part of the Difeafe, and is rather to be' 

 cured than encouraged ; and therefore fuch Medicaments 

 are to be ufed as will be of EfBcacy, not only to break 

 thofe Vifcidities which obftrudt the Capillaries and fmall 

 Veflels, but alfo to draw up the Solids into fuch a Tenfi- 

 ty, and recover their Vigour to fuch a Degree, as is necef- 

 fary to prevent the Increafe of fuch Matter for the Time to 

 come ; for it is by this lail Intention, that Digeftion, and 

 a due Comminution of the Juices, is to be perform'd. 

 The Cure Therefore, if a Horfe labouring under this 



Diftemper be young, and has not been too 

 much v/ore out by the Continuance of his Sicknefs, a mo- 

 derate Quantity of Blood may be taken from the Neck- 

 vein J but this mult be done with Difcretion ; for if the 



Horfe
