side. The tissues covering the upper part of the neck were completely, 

 and the ligamentum nuchas partially divided, especially on the left 

 side. 



Towards its centre the wound was six inches broad and three to 

 three and a half inches deep. Opposite the line of the vertebras it was 

 two and a half inches in depth, and extended through the muscular tis- 

 sues. The upper part was somewhat shallower. The greater portion 

 of both surfaces of the wound was covered with dried exudate, and the 

 deeper portions contained masses of blood-clot. The animal was 

 depressed and feverish ; it only ate a portion of its food ; the tempera- 

 ture was 39*5° C. 



Treatment. — Thorough disinfection of the wound with a warm one 

 per thousand solution of sublimate, insertion of deep-seated sutures, and 

 application of moist antiseptic compresses. 



November 20th. — The wound had become clean. Some fragments 

 of dead tissue had been shed. Suppuration was trifling. Temperature 

 39-2° C. 



During the following days the wound granulated over its entire 

 surface. The muscular layers became united. The depressions filled 

 up and suppuration remained slight. In spite of the extent and depth 

 of the wound the neck was easily moved in all directions. The appetite 

 was good, and the temperature normal. 



On the 5th December the use of moist compresses was discontinued, 

 the wound being simply washed out night and morning with an anti- 

 septic solution. On the 20th it had almost filled up ; the margins were 

 nearly in contact, and at the widest part were only separated by a 

 distance of an inch and a quarter.

43. Fifteen-year-old gelding, sent to the School from the Pasteur 

 Institute on the 27th February, i8g8. 



It had first been treated at the infirmary of the Institute for an open 

 sinus on the left side of the head. Carbolic and sublimate injections 

 had proved unsuccessful. 



On the 28th the horse was cast on the right side. The sinus, which 

 opened almost on the median line, extended obliquely downwards and 

 backwards parallel to the ligamentum nuchas, and was about six inches 

 in depth. 



Treatment. — The sinus was exposed and a counter-opening formed. 

 A gauze drain was inserted, and the parts washed out night and morn- 

 ing with 30 per cent, tincture of iodine, and with Villate's solution. A 

 prophylactic injection of antitetanic serum was given. 



Though continued until the 15th March this treatment by drainage 

 and injections produced no improvement. Operation for poll-e\'il was 

 then decided on. 



The animal was cast on the table, and the cordiform portion of the 

 ligamentum nuchas removed up to the point where it becomes inserted 

 into the occipital bone, the latter being scraped. The wound was 

 cleansed with warm sublimate solution, powdered with iodoform, and
