are maae like Hooks, or Sickles-, and they are to be u(ed where the 

 Wound is crooked, for the burning out of dead Flef)^, or fuch like hid- 

 den evils, which cannot be reached by any firait Inftruments. Others are 

 made either with great Buttons, or little Buttons at the end ^and they are 

 uled to open Impofthumes, or elfe to burn into the found Flefh, where 

 you intend to make any new Sore or Iffue, for the drawing, or keeping 

 back of other evil Humours. And in making of ihefe Irons, the Farriers 

 own Judgment is to be of great value, becaule he muft either increafe or 

 diminifh them, according to the manner of the place grieved, and be fure 

 that he ever make them fit for his right purpofe. 



Now for the ufe of thefe Inlirurr.ents, there are two principal things 

 to be regarded, firft the heating of the Iron^ and next, the true temper, 

 or bearing of the Farrier's hand. 



Touching the heating of the Iron, you Ihall underhand, that the back 

 of the Iron muft never be fo hot as the edge^ that is to fay, .you mutt 

 never make the back of the Iron red hot, for fear that thereby it yield too 

 much heat, and conftquently breed Inflammation: Therelore, whenfoever 

 you fee ihe back of your Iron as hot as the edge, you fhall a little cool it 

 with Water. 



Now for the temper of the bearing of your hand, you Oiall underhand, 

 that the more evenly and light it is done, fo much the better, it is done: 

 And herein is to be confider'd the finenefs or thicknefs of the Horfe's skin, 

 which you (hall know moft commonly by his Hair; for if it be (hort and 

 fine, then the skin is thin^ if it be long and rough, then is his skin thick 

 and boifterous. 



Now the skin that is fine muft be cauterized or feared with a very 

 light hand, inafmuch as the skin is foon pierced thro', and the thick skin 

 with a heavy hand yand both of them with fuch a tempered hand, that 

 the skin muft no more but look yellow ^ wherein you fhall ever find, that 

 the fine skin will foonetlook yellow than the thick skin 5 the main rea- 

 fon being, becauie the thicknefs and roughnefs of the Hair of the thick 

 skin doth cool and choak the heat of the Iron j infomuch that if it be 

 not laid to with a more heavy hand, and the Inftrument fo much the 

 more and the oftner heated, it cannot work that effeft which in Art ic 

 fhould do. 



Now you (hall alfo oblerve, that in drawing of any Line or other Cau- 

 terize whatfoever, that you ever draw with the Hair, and never againft the 

 Hair, whether the Lines be (hort, long, deep, (hallow, ftrait, crooked, or 

 overthwart, according as the Grief doth require. 



Now, to conclude, you are to obferve, in Cauterizing, thefe few Pre- 

 cepts : Firft that you do not give fire to any finew Place except there be 

 fome apparent Swelling^ or dfe Impofthumaiion. Secondly, that you
