TUBERCULOSIS IN THE DOG. 47 1 



and the ris^ht hemisphere appeared softened. In the anterior and 

 upper portion of the left hemisphere a superficial depression was 

 observed, the discoloration being more marked over that area. Incision 

 through this depression revealed a very large tubercular nodule. The 

 tumour was about the size of a walnut, caseated, and undergoing 

 calcification. The cut surface was of a dirty yellow colour, and showed 

 numerous calcareous particles, rather larger than coarse sand. 



The submaxillary lymphatic glands were tuberculous. 



Microscopic examination of the brain revealed the presence of 

 tubercle bacilli. 



Note. — The most striking points in the case are (i) the sudden 

 development of symptoms, a characteristic also commonly noted in 

 tuberculous children ; (2) the subnormal temperature ; (3) the absence 

 of tubercular meningitis ; and (4) the good bodily health and condition 

 of the patient.

EXTERXAL LESIOXS OF TUBERCULOSIS IX THE DOG. 



168. A two-year-old Havanese bitch, brought for examination on 

 the ist May, 1894, suffering from a sinuous wound in the neck. 



Three months before, a swelling had appeared in the upper part of 

 this region, and had increased in size until it became as large as an 

 egg. After poulticing it softened and ulcerated, discharging pus, at 

 first freely, and afterwards in less quantity. The wound became 

 sinuous, was treated by antiseptic injections, and had several times 

 been laid open. 



State on Examination. — The patient was fairly well nourished. On 

 examining the abdominal and thoracic cavities no symptom suggesting 

 tuberculosis was noted. 



Over the median line of the larynx was a wound, as large as a 

 sixpence, the margins of which were torn and irregular, separated 

 from the deeper seated tissues, thickened, exuberantly granulating, at 

 certain points thin, at others eroded, but in all parts covered with 

 greyish viscous pus. Two little sinuses opened at the base of the 

 wound and extended deeply along the sides of the trachea. Slightly 

 below this first wound was another, similar in size, also sinuous in 

 character, and separated from the first by a fragment of skin about 

 two and a half inches wide. On the left surface of the neck, behind 

 the lower portion of the parotid, was a cold abscess, as large as a hazel- 

 nut. When punctured it discharged greyish watery pus, which, like 

 that collected from the wounds, contained tubercle bacilli. 



This animal was not left in hospital or brought back again for 

 examination, 



i6g. A four-year-old bitch, several times brought to the external 

 chnique during the early part of 1894. Belonged to a tuberculous 

 person. 



Had been ill since the end of January. The owner had particularly 

 noticed coughing and rapid emaciation, followed by diarrhoea and
