teiiipl to raise an artificial infiammation iii the neigh- 

 bourhood by means of blisterS;, which, if we effect, 

 we remove, or at least lessen, the more natural in- 

 flammation. Therefore, in inflammations of the 

 lungs, bowels, &c. it is proper to blister the chest, 

 belly, &c. very extensively, by which means the in- 

 flammation mav be removed from the vital organs to 

 parts of less importance. 



The substances used as blisters are various; the 

 more active are, corrosive sublimate, Initter of anti- 

 mony, oil of vitriol, euphorbium, &c. : the more 

 mild are, preparations of Spanish flies, of horse-ra- 

 dish, mustard, &c. Great care is necessary in the 

 compounding of blisters to advantage, as well as 

 much judgm.ent: they are frequently so strong as to 

 leave a blemish through life, and this is particularly 

 the case with euphorbium and corrosive sublimate. 

 I have succeeded in compounding an ointment equally 

 adapted for all the purposes of blistering, distin- 

 guisiied in the medical arrangement under the title — 



Blistering Ointment [see page l6]. This 

 will be found efficacious in all bony swellings, as 

 curbs, splents, bone-spavins, ring-bones, &c.; blis- 

 tering the skin actively, w ithout destroying the roots 

 of the hair, and blemishing the part, as is frequently 

 tlie case with the blisters in use for these complaints. 

 It likewise will be found a most excellent application 

 when blisters are required for old strains of any part ; , 

 elaps of the back sinews, ruptured ligaments, and 

 in every case requiring an active but safe blister. 



Liquid Sweating Blister [page 17]. There 

 are some cases in which a more salutai*y effect is pro- 

 duced by gently stimulating an affected part for a
