it being what the celebrated cancer doctors of the age 

 call the real kill devil, pretending it only grows in 

 some obscure place on the Catskill naountains, &c., and 

 is comnuonly known by the name of swamp ash. Either 

 the black or red ash (fraximus pubescens) will answer. 

 The bark only is to be used for this purpose, and that 

 reduced to ashes and leached, and the lye boiled down 

 to a salve, &c., which should be applied once or twice 

 a day until these pipes or roots are eaten entirely out. 

 Clean off the excrescence every time before applying any 

 more salve, with castile soap and water, using as much 

 perfumery or as little as you choose on the surrounding 

 parts. When this is thoroughly done, use the following 

 salve until it is healed up smooth: Take equal parts of 

 yellow pine turpentine and honey, with a quantity equal 

 to both the former of a decoction of the white oak bark, 

 and simmer these over a slow fire down to a salve. 



Fistula on the Withers, differs bwt very little in its na- 

 ture from that of poll evil, except in its lr;cation. It 

 may be caused by being bruised with the saddle or collar; 

 or, like sweeny, it may be caused by checking the draft 

 horse too high (or too long at a time), which causes more 

 friction at the point of the shoulder blades, and has a 

 tendency to tire and weaken the muscles of the neck, 

 and, by taking cold, it may settle at this point and pro- 

 duce inflammation and swelling. And the horse may be 

 made to bruisre the withers by rubbing himself or rolling, 

 in consequence of the irritation produced on these parts 

 by the former. 



Cure. — Observe entire rest, and treat precisely as you 

 would poll evil, and a cure will be effected in a few days*
