CHAP. LXXI. 

 Of the Bone-fpavin. 



^Tp H I S is a hard bony Excrefcence growing on the Infide 

 ■*■ of the Hough, not far from the Elbow, and is genera- 

 ted of the Matter which nourifties the Bones and Ligaments, 

 Some Horfes are foal'd with this Imperfeftion ; but it pro- 

 ceeds, for the moft part, from ftraining, while a Horfe is too 

 young to bear violent Fatigue, which, in Procefs of Time, 

 caufes Lamenefs. 



rt-» f^ The main Intention in the Cure, is to re- 



move the Excrefcence, but this is hardly prac- 

 ticable when it adheres to the Bone as a Part of its Sub- 

 ftance, but only when it lies as an Appendage, in which 

 Cafe it may be removed by a dexterous Application of the 

 Fire, or by the Ufe of cauftick Ointments j for thefe, by 

 bringing a Flux of Matter, and a conftant Moifture into 

 the Part, will, by Degrees, loofen that hard Subftance from 

 its Adhefion, fo that it may be eafily taken off s and for 

 this Purpofe we recommend the following. 



*' Take Quickfilver and Brimftone, of each two Oun- 

 ** ces ; rub therrt in a Mortar until they turn to a black 

 *' Powder ; then take Spanijh Flies and Euphoibium in 

 *' Powder, of each fix Drams, Corrofive Sublimate two 

 *' Drams, the Apoftles Ointment four Ounces. Mix them 

 *' cold in a Mortar, or on a A^arble, 



The Method of applying this Ointment, is firft to rub 

 the Part with a piece of any round fmooth Stick, and then 

 lay over a flicking Plaiftcr to guard the reft of the Hough ; 

 this mufl be made of Rofin, common Pitch, or Burgundy 

 Pitch, fpread on a thick Piece of Leather, having a Hole 

 cut in the Middle, that the Tumor may come thro' it, up- 

 on which the Ointment is to be apply'd, the Hair being 

 alfo fhav'd away, over which mufl be laid a Pledgit of 

 clean Hurds faflened with an eafy Bandage round the 

 Hough, and another fticking Plailler over all. This Oint- 

 ment will at firft draw out a thin Water ; but after two or 

 three Days Application, it will form an Efcar, which may 

 be fcarrify'd with a Fleam or Lancet, continuing the Ap- 

 plication every other Day until the Bone becomes loofe, or 

 its Subftance diflblves j and after it is removed, the Ulcer
