Chap. V. Some general Rtiks-, ^(£. If 



But we {hall lay down feme of the particular Indications* 

 which chiefly call for that Operation ; and in doing there- 

 of we fhall not tie any one up to Times and Seafons, or 

 particular Influences, which we find fo much obferv'd in 

 Books of Marfhalfy, and in old phyfical Writers ; for, ac- 

 cording to their Doiftrine, fome Part of the animal Body 

 mull: have been difeafed every Month. All the Caution 

 therefore, that is to be had in that Refpedt, is only to avoid 

 it as much as poflible in the Extremities of Heat and Cold, 

 excepting when fome urgent NeceHity requires it. 



Now the Signs that require Blood-letting, n-L q- .?

which may he difcovered in a Horfe, be- /^^/^w 



caufe fuch a one will be apt to be purfive 



when he is piit to any kind of Exercife, and his Stomach 



will fomewhat abate. In fuch a Cafe Bleeding cools and 



refreflies a Horfe wonderfully. 



Secondly^ Blood-letting is propsr in the beginning of at- 

 moft all Fevers, whether flmple or complicated ; that is to 

 fay, whether the Fever confifts Amply in an Augmentation 

 of the Blood's Motion only, or when the Blood is befides 

 that vitiated. But Care muft be taken, if the Diftemper 

 takes its Origin from the want of Blood, as very often hap- 

 pens after large Hemorrhages, or after long fcouring, or 

 alter a too plentiful Ufe of Evacuations, or when a Horfe 

 has been fome lime in a declining Condition ; in fuch 

 Cafes, tho' fome Indications may, perhaps, require Blood* 

 letting, yet it is to be us'd fparingly. 



Thirdly^ A Horfe ought to be Bled for all Swellings and 

 Impoflhumations, when they happen to be lituated oii any 

 Part of the Body, fo as to endanger a Suffocation, or any 

 other ill Accident ; but if there be none of thofe Appear- 

 ances, and at the fame Time have a Tendency to Suppu- 

 fation. Bleeding ought not to be perform'd, becaufe that 

 would be manifeftly to oppofe Nature, \vho herfelf is en- 

 deavouring to throw off v/hat is hurtful to her in another 

 way ; but in Si\'ellings of the Legs, occafion'd by ths 

 Greafe, Blood-letting is not only fafc in the Beginning, as 

 it may make a Revulflon, but neceil'ary before they ate 

 much inflam'd, or come to break ; becaufe this Dillem- 

 per at firft proceeds chiefly from a Stagnation of the Blood 

 in the extream Parts, from the Smallnefs of the Vellels, 

 i3c. and not from any manifefl Diforder in the Blood it- 

 felf. But of this in its proper Place,
