TUBERCULOSIS IN THE CAT. 473 



formed by the thickened pleura, the external by the eighth, ninth, and 

 tenth ribs, which were denuded of pleura, inflamed, and at some points 

 softened. Over the ninth and tenth intercostal spaces this cavity 

 communicated with the external swelling seen during life. It contained 

 a little greyish pus and fragments of necrotic tissue. 



171. A fifteen-month-old spaniel, brought to Alfort on the 6th July, 

 i8g6, to be killed. Had been ill for about a year, and showed a 

 suppurating wound on the neck, which had been unsuccessfully treated 

 for a long time. 



Autopsy. — Tuberculosis of the liver; old standing pulmonary 

 tuberculosis with cavern formation. The wound in the neck, over the 

 origin of the trachea, was rounded, ulcerated, and the size of a two- 

 shilling piece. Its margins were denuded of hair, and the skin was 

 thinned and separated from subjacent tissues. Its base showed a sinus, 

 which extended as deep as the left retro-pharyngeal glands. These 

 formed a swelling the size of a pigeon's egg, were hard, and firmly 

 attached to the surrounding parts. The sinus had originated in several 

 small purulent, caseating nodules at this point. The lower half of the 

 left tonsil was destroyed by an ulcer, with a yellowish, finely granular 

 base and indurated margins. 



The tuberculous character of the wound in the neck, the inflamma- 

 tion of the retro-pharyngeal glands, and the ulcer in the tonsil was 

 proved by the discovery of bacilli in each of these lesions. 



TUBERCULOSIS IN THE CAT. 



172. A one-year-old female cat, brought for examination on the 

 igth June, 1894. 



The history was as follows : — About six weeks previously this cat 

 had shown signs of chest disease, particularly cough and difficulty in 

 respiration, followed by loss of appetite and wasting. For three days 

 before the animal had not touched food. 



This history, together with the results of clinical examination, and 

 the chronic character of the disease, caused us to suspect tuberculosis. 

 The owner would not allow the animal to be left, but brought it back, 

 however, on the 7th July, when it was killed. 



Autopsy.— Over the terminal portion of the small intestine were 

 some tuberculous lymphatic glands, the size of hazel-nuts. In front 

 of these were five smaller lymphatic glands arranged like a row of 

 beads, parallel to the intestine. The epiploon showed a few tubercles 

 as large as peas. The mucous membrane of the ileum exhibited two 

 ulcerations : one, oval in form, with its longer diameter parallel to the 

 intestine, measured half an inch in length and three eighths in 

 breadth ; the other was narrower, with indurated prominent margins. 

 Liver large, crammed with greyish tubercles, the size of millet seeds, 

 at certain points confluent ; on the posterior surface of the organ 

 hundreds could be counted. Spleen three times the normal size, both 

 surfaces bosselated by tubercles, some as large as a pea. The lungs 

 were firm, dense, fibrous, and greyish in colour ; showed generahsed
