covered with compresses of iodoform gauze, over which was appHed a 

 compress dressing of cotton wool kept in position by three bandages. 



On the second day after operation the dressing was removed and 

 the wound washed out with warm subhmate solution. A fresh gauze 

 and cotton-wool dressing was applied. The dressings were changed 

 every second day until the 3rd Ma}-, when the wound was granulating 

 throughout. 



SINUS OF THE NECK. 



44. Eight-year-old gelding, left in hospital the 27th August, i8g8. 

 For the previous three weeks this horse had shown a diffuse, very 



tender swelling in the upper part of the neck, the centre of the swelling 

 being occupied by a large partially detached slough, which appeared to 

 extend deeply towards the ligamentum nuchae. 



Treatment. — The greater part of the dead tissue was excised. Two 

 incisions in the shape of a cross were made, one in the axis of the neck, 

 the other transverse to it ; and in addition a counter-opening was 

 made on the right side, in which a strip of gauze was placed to act as 

 a drainage-tube. Night and morning the wound was disinfected, the 

 margins powdered with bicarbonate of soda, and the parts covered with 

 compresses saturated with warm 5 per cent, bicarbonate of soda solu- 

 tion. This treatment was continued for a week. Suppuration remained 

 abundant, and the swelling large and painful. 



From the 5th September the parts were dressed with a weak 

 solution of formalin and a mixture of calomel and iodoform. This 

 treatment proved very successful. The wound soon assumed a better 

 appearance. The pus became thicker and less abundant, while the 

 parts lost their extreme sensibility. 



On the 30th September the necrotic portions of the ligament had 

 separated, and the entire surface of the wound was actively granulating. 

 The neighbourhood of the wound still remained very sensiti\'e in conse- 

 quence of irritation of the skin. 



MOIST GANGRENE IN THE NECK REGION. 



45. A thirteen-year-old entire horse, left in hospital 28th April, 



^893- . . 



This animal had been injured a little in front of the withers by the 

 collar. The neighbourhood of the wound and the upper margin and 

 sides of the neck became much swollen. A veterinary surgeon 

 punctured the swelling on both sides with a pointed firing-iron, but 

 tumefaction increased during the following days. 



State on Examination. — Depression ; loss of appetite ; anxious 

 appearance of the face ; mucous membranes cyanotic ; respiration and 

 circulation rapid ; temperature 39*6° C. The whole of the neck was 

 enormously swollen ; sloughing had occurred in the upper half, and the 

 lower was cedematous. At the centre of the upper margin was a sinus 

 into which almost half a litre of liquid could be injected. On the right 

 side the necrotic parts were beginning to separate.
