Bwelling is less. Among the pus will be observed organized mat- 

 ter, similar to cheese, or in other words, not uniform in thickness 

 or appearance. This is a disease that rarely ever gets well of its 

 own efforts, from the fact of the sore ha^ving a sack, which is only 

 removed by art ; also from the situation of fistula presenting no 

 depending opening for the outlet of pus. 



Causes. Bruises, accidents, caries of the bones (which see), in- 

 flammation of the bone, or any accident that will cause a simple 

 abscess, will cause fistula. 



A blow that would produce a common abscess on some portions 

 of the body, will result in fistula in other portions, as in the vicin- 

 ity of a joint. 



Treatment. If the swelling is just forming, endeavor to put it 

 back by placing chopped ice, in a bag, over it for a few days. By 

 this means, many a swelling which would terminate in a fistula, 

 will be cured at once. This not succeeding, have an opening made 

 into its lower side, so as the bloody water, which it at this time 

 contains, will be discharged. Then syringe a half tablespoonful 

 of the tincture of iodine into it once a day for a few days, to eat or 

 destroy the membranous sack. Then treat it as a common sore 

 by keeping it clean, and the opening from closing before it has 

 healed from the bottom. For this purpose, place a small piece of 

 cotton in the .mouth of the opening, smeared with simple oint- 

 ment. (See Medicines and Prescriptions.) 



Fistula in the Foot. — This disease, by common consent, ia 

 called quittor, a fistulous abscess in the foot. (See Quittor.) 



Fistulous Withers. — By farmers called Thisolow, or Pisolow. 

 This is an affection described in the preceding article, with this 

 difference in some cases, that it extends through over the top of 

 the bones of the withers or shoulders to the other side, thus form- 

 ing a very broad pad, as it were, on the top of the shoulder, just 

 where the shoulder in health is the sharpest and narrowest. 



Treatment. Lay chopped ice in bags over the swelling, and, if 

 necessary, open and take out the sack, or destroy it by the injec* 

 tion of the tincture of iodine, and dress as for a common sore.
