DISEASES AND TIIEIE TEEATMENT. 



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 Avith- 

 ers. First, cooling applications, a dose 

 of physic, and a cooling, opening diet. 

 A favorite prescription for dispers- 

 ing inflainmation of this kind, used by 

 an old author. 



IS, 



Fig. S50. — Method of checking 



that is liable to cause 



poll evil. 



2 drachms tartarized antimony, crj's- 



alized and finely powdered, 

 2 drachms olive-oil, 

 1 oimce hosf's lard. 



Vaseline can be substituted for the 

 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 

 same as for fistula of the with- 

 ers, being careful to I'emove 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-
