and trcjated in tlie same way. A change of dressing is 

 sometimes needed as one appears to be losing its eflect 

 (tincture of muriate of iron 1 oz., water 1 quart). lu ob- 

 stinate cases it is sometimes needful to lay the sacs open 

 by an extensive incision and treat like an ordinary wound. 

 Bat all these operations are only safe in the hands of 

 those who are intimately acquainted with the structure of 

 the part. 



In case of disease of the bone it may be felt bare at the 

 bottom of the sac, by probing, and may be scraped to re- 

 move any dead or diseased part, and expose sound bone 

 t^rhich may undergo the healing process. 



If the joint is implicated the case may be deemed des- 

 perate, as it is usually only a question of time for the 

 spinal cord to become iavolved. 



HtSTULOUS WITHERS. 



This is analogous to the milder form of poll evil, differing 

 only in its site, which is on the spines above the shoulders. 

 It is to be treated in the same way, by free incision, the 

 formation of a dependent orifice and injections. If the 

 spinous processes are diseased they should be removed 

 with bone forceps until a healthy surface is exposed. 



FBACTUBED PEOCESSES OP THE NECK BOKES. 



This may arise from muscular effort but more commonly 

 results from jamming between two heavy bodies. If on 

 one side only, the head is drawn to a side ; and in any case 

 the detached piece of bone may be felt among the muscles 

 and grating even may be produced by moving it. The 

 only treatment is to keep the head in one position until 

 the detached parts have become adherent, which they 

 usually do with a visible swelling. If abscess or fistula 

 forms the detached bone must be extracted. 



TEANSVEESE FEACTUEE OP THE BONES OP THE NECK 



These occur from pitching on the head, and are fatal 

 from the sudden cessation of breathing.
