How to judge of the Quantity and Quality of Blood. 



ALtho' it is not the common pra&ice of Farriers 

 to receive a Horfe's Blood into a Veflel, how- 

 ever, it is very neceffary, that a Man may thereby be 

 able to judge of the Quantity and Quality. 



A Quart of Water weighs about two Pounds, and 

 Blood is near of equal weight with Water : There- 

 fore firft try how many Pounds of Water the Veflel 

 contains, and when you know how much fpace two 

 Quarts of Water will take up in a Veflel, the fame 

 fpace will be filled with four Pounds of Blood. 



Obferveifit run calmly and flowly, and without 

 impetuofity \ as alfo if it cleave to your Fingers 

 when you touch it, becaufe if it do, it is a fign that 

 it is Vifcous, and apt to occafion obftrudtions : 

 Therefore in that cafe you are to bleed your Horfe 

 frequently. 



Blood which froths much when receiv'd into a 

 Veflel at a pretty diftance, betokens heat and agita- 

 tion of the Spirits ; from whence People conclude, 

 that a Horfe is over- heated, either by fuperfluous 

 Nourifhment, or too violent Labour *, or otherwife, 

 that he is of a vigorous Conftitution : Such Horfes 

 Ihould be let Blood at leaft twice in the Year, by way 

 of Prevention. 



When Blood coagulates foon and eafily after it is 

 drawn, and hath a great many Fibres in it, it is a 

 fign that its Subflance is thick and terreftrial , but 

 if it with difficulty congeal, than it is more fluid 

 and fubtil. 



If the Blood be very ferous, that is, Watery, it 

 betokens a Weaknefs in the Reins, or an Obftru&km 

 in the Veins.
