of the Joint. It happens chiefly to draught Horfes, and 

 is hardly curable by any other Means than Fire ; however, 

 the Medicines direded in the proceeding Chapters may firft 

 be compiy'd with, or the Plaifter of Frogs, with four times 

 the ufual quantity of Quickfilver, may be laid to the Curb, 

 firft fhaving away the Hair, and renewing it once a Fort- 

 night. This Plaifter is fomewhat troublefome to make, but 

 it may be had of any Apothecary when befpoke ; and I dare 

 anfwer it will be of the greateft Service to remove all hard 

 Swellings on the Bones or Sinews, by difcufling them ; 

 fometimes it has the Efte6t of a fuppurative Plaifter, and 

 will caufe an Impofthumation, which equally anfwers the 

 End, as thefe Sort of Tumors often terminate that Way 

 with good Succefs. But they who will give themfclvcs the 

 Trouble to make it, may obferve the following Method,

^'F'HIS is a hard callous Tumor a httle below the Bending 

 ■*• of the Ham on the Outfide ; it is at firft fcarcely dif- 

 cernable, but in Time caufes the Horfe to halt, and grows 

 fo painful as to make him pine away, and become light 

 beliy'd ; but it happens moft frequently to manag'd Horfes, 

 ffpecially ihofe who have been kept too much on their 

 Haunches. The Cure may be firft attempted by applying 

 the Mercurial Plaifter, as above direded ; but if it proves 

 obftinate, it muft be treated as a Bone-fpavin, i^r.
