PSEUDO-CANCROID OF THE LIP. 325 



This growth, situated on the upper Hp, shghtly to the right of the 

 middle line, was about a quarter of an inch in length, and one eighth 

 inch in depth, its margin appearing as though cleanly punched out ; its 

 base was slightly hardened, and its surface covered with a thin, greyish, 

 dry, adherent crust. The right submaxillary gland was slightly 

 swollen. 



Treatment. — The parts were dressed daily with a 4 per cent, solution 

 of chlorate of potash, and every third or fourth day were swabbed with 

 a 10 per cent, solution of methylene blue (methylene blue, ten parts : 

 alcohol, fifty parts; glycerine, fifty parts). 



The animal was very gentle, and made no opposition to the dress- 

 ing. By the beginning of June the slight induration about the base of 

 the ulcer had disappeared, the extremities and the cutaneous and 

 mucous margins were seen to be healing, while the submaxillary glands 

 were less hard. 



Treatment was stopped on the 15th June. Ten days later recovery 

 was complete, except for the notch produced by ulceration. 



27. Two-year-old female cat, brought for examination on the 

 igth April, i8g6. 



Was suffering from ulcer of the lip. This ulcer had developed on 

 the right side of the upper lip, causing a crescent-shaped loss of sub- 

 stance, about three eighths of an inch in depth at its centre, and 

 extending as far as the right labial commissure. It was very sharply 

 defined, its base a little indurated, but not painful on pressure ; the 

 surface was greyish in colour, and marginated by a narrow, pale red 

 line ; examined more closely it appeared stippled wath a large number 

 of minute depressions. 



On examining the jaw the right submaxillary gland was found 

 inflamed and multilobular. 



Treatment consisted in dressing the ulcer with methylene blue. 



This animal was not brought back. 



28. Three-year-old female cat, left in hospital 4th September, 1897. 

 Suffering from labial ulcer. In October, i8g6, it had been brought 



here on account of a similar lesion, which, however, healed in a few 

 weeks. 



On examination a large superficial ulcer was seen covering all the 

 left side of the upper lip ; the lower lip of the same side close to the 

 commissure was also invaded over a surface three eighths of an inch in 

 length. 



Treatment. — Daily application of methylene blue solution. 



Up to the loth there was no change, but during the following days 

 fine granulations appeared. 



On the 30th the ulcer had healed. 



Remarks. — In the dog the lips, especially the upper, are sometimes 

 the seat of ulcers of an apparently cancroid nature which, however, are 

 not in reality due to new growths but probably to lesions resembling 

 labial ulcer in the cat.
