CHAP. CXXXI- Of the Canker in any fart of the Bair. 



A Canker is a poifonous creeping Ulcer^ fretting and gnawin^j the 

 Flefli a great breadth^ whofe Beginning is Knotty, not much 

 unlike to the Farcy, and fprcadeth it felf into divers Places ^ andbeln'^ 

 exulcerated, gathereth together at the length into one Wound or filthy 

 Sore, from whence there runneth a thin Aarp Lye, which gallerh off 

 the Skin wherefoever it goes, and io both encreafeth the Ulcer, 

 and maketh it more incurable. It proceedeth from melancholy and 

 filthy Blood, ingendred either by rankneis of keeping, or elfe by too 

 extream Poverty; and if this naughty Blood be mixt with fharp or 

 fait Humours, then it caufeth more painful and grievous Exulceratfon. 

 It alfo may proceed from fome I.oathfome Wound, which is neither 

 clean kept nor well dreft, but in fuch fort, that the corrupt jMatter 

 thereof poyfoneth the other clean parts of the Body. For Signs of 

 this Sorance, there needeth no more but the Defcription already menti- 

 oned: And for the Cure, according to the Opinion of the' ancient 

 Farriers, it is, Firft to let the Horfe Biood in thole Veins which are 

 next the Sore, and make him bleed well,- then take of Allom half a 

 pound, of Green Copperas as much, of White Copperas one quartern 

 and a good handful of Salt, boil all thefe things together in fair running 

 Water, from a Pottle to a Quart; and this Water being warm, wafh 

 the Sore therewith with a Clout, and then Iprinkle thereon the Powder 

 of unllackt Lime, continuing fo to do every Day once the fpace of fif- 

 teen Days; and if you fee that the Lime do not mortifie the rank Flefii 

 and keep it from fpreading any further, then take of Soap half a 

 pound, of Quickfilver half an ounce, and beat them together in a 

 Pot till the QHickfilver be (o well mingled with the Soap, as you can 

 perceive no Quickfilver in it ; then with an Iron Slice or Splater after 

 that you have wafned the Sore with the ftrong Water aforefaid, 'cover 

 the Wound with this Ointment, continuing thus to do every Day once 

 until the Canker leave fpreading abroad: And if it leave fpreading 

 and that you fee the rank Flefii is well mortified, and that the Edges 

 begin to gather a Skin, then after the wafhing, drefs it with Lime as 

 before, continuing fo to do until it be whole ; and in the drefling, fiiffer 

 no filth that comes out of the Sore to remain upon any whole Place 

 about, but wipe it clean away, or elfe wafh it away with warm Water • 

 and let the Horfe during this Cure, be as thinly dieted as may be, and 

 throughly exercifed. Now if this Cankerous Ulcer happen tobe in 

 the Tail ot a Horfe, as it is often feen, and which you fhall perceive 

 as well by the tailing away of the Hairs, as alfo by the Wound, then
