three sinuses, one of which opened at the base of the depression result- 

 ing from the operation wound. On direct manipulation the cord was 

 found to be enlarged and indurated, forming a pear-shaped swelling, 

 flattened below, where it was adherent to the envelopes, and contracted 

 above, where it could be followed as high as the lower inguinal ring. 

 On rectal exploration the intra-abdominal portion of the cord was 

 found to be normal. Pus collected from the sinuous openings was 

 greyish in colour, fairly consistent, and contained small yellowish- 

 white granules, which, on microscopical examination, were seen to be 

 formed by bothryomyces. 



Treatment. — From the 8th to the 20th November, and from the 

 25th November to the loth December, this horse received a daily dose 

 of two and a half to four drachms of potassium iodide in its drinking- 

 water. Each day the swelling was swabbed with iodine solution, and 

 the sinuses injected with tincture of iodine. There was no improve- 

 ment. 



On the loth December the tumour was removed, the cord being cut 

 through with the ecraseur. No dressing was applied. 



During the following days the wound was cleansed night and 

 morning with warm creolin solution. It healed rapidly and uninter- 

 ruptedly. The animal returned to work at the end of three weeks. 



179. An eight-year-old gelding, left in hospital the 27th September, 

 i8g8. Affected with swellings in different regions, the largest opposite 

 the base of the neck. The disease had been in existence for nearly a 

 year. 



Swelling had first appeared in front of the left shoulder, and had 

 been followed by further growths. As the swelling on the shoulder 

 became so large as to prevent the animal being worked, it was sent to 

 Alfort for operation. 



State on Entry. — On the sides of the thorax and neck were small 

 nodules varying in size between a nut and a small egg, almost all 

 pierced with sinuous tracts discharging pus, in which bothryomyces 

 were found on microscopical examination. The largest was situated 

 over the jugular furrow. It measured ten inches in a vertical and six 

 inches in a horizontal direction, and was formed of firm, resistent 

 tissue. Its upper part was only slightly adherent to subjacent tissues ; 

 but its lower penetrated more deeply, and had become intimately 

 adherent to the deep-seated tissues as well as to the skin. The swell- 

 ing showed elevations and depressions, and was penetrated by several 

 sinuous openings discharging pus, in which numerous little bothryo- 

 mycotic granulations could be detected. 



Treatment. — Before resorting to operation two and a half drachms 

 of potassium iodide were given daily in the drinking-water, while the 

 swelling was swabbed and the sinuses injected with tincture of iodine. 

 This treatment was continued until the 13th October without the 

 slightest success. The owner saw the horse on that date, and asked 

 us to operate. 



Next day the horse was cast on the straw bed. The parts having 

 been prepared and disinfected the growth was excised.
