988 DISEASES AND THEIR TREATMENT. 



occipital bone, and sometimes the atlas bone, also the strong ten- 

 don over them, will be involved, causing serious ulceration of the 

 parts, unless taken in hand promptly. The principle of treatment 



is precisely that of fistula of the with- 

 ers. First, cooling applications, a dose 

 of physic, and a cooling, opening diet. 

 A favorite prescription for dispers- 

 ing inflammation of this kind, used by 

 an old author, is, 



2 drachms tartarized antimony, crys- 



alized and finely powdered, 

 2 drachms olive-oil, 



1 ounce hog's lard. 

 FIG. 850. Method of checking 



that is liable to cause Vaseline can be substituted for the 



P H evi1 ' oil and lard. When properly rubbed 



on the part, this will act as a powerful blister, but does not blem- 

 ish. Should matter form, it must be opened to the bottom, and, 

 after being cleansed out, ascertain how far matter has bur- 

 rowed, or the degree to which sinuses have formed. It is not 

 prudent to do any more cutting at this part than simply to 

 make a sufficiently deep incision to give an opening for the matter 

 to pass off. If sinuses have formed, caustic tents are to be intro- 

 duced, as before explained, until a clean sore is made. If the 

 bones are involved, they must be scraped. Next, a depending 

 opening made by running a 

 seton from the bottom outward. 

 Sometimes the matter extends 

 across the neck to the opposite 

 side. In such a case, the best 

 way is to run a needle across 

 between the muscles, and out 

 on the opposite side, making an 

 outlet on both sides. 



The after treatment is the FIG. 851. The head as it should be given 



same as for fistula of the with- freedom in harness ' 



ers, being careful to remove all foreign growth, or diseased bone. 

 Dress first with slightly caustic solution, then with digestive oint- 

 ment, as explained. 



I will include here a remedy which is claimed to be very ef-
