TUBERCULOUS LESIONS OF THE SKIN AND APPENDAGES IN PARROTS. 56 1 



Case 6. A parrot which had shown marked wasting for several 

 months. On the right side of the head was an indurated cutaneous 

 patch the size of a sixpence ; at the lower part of the neck was a 

 horny growth as large as a haricot bean ; on the back a similar but 

 smaller patch ; finally, on the sacrum a fungous, bleeding, ulcerated 

 spot. Examination of these various lesions revealed the existence of 

 numerous bacilli. 



Case 7. A parrot brought to hospital on the 4th May, 1894. It 

 was thin, dull, and had not talked for several weeks. On the right 

 side of the head, three eighths of an inch from the base of the beak, 

 was a horny growth, conical in shape, covering a surface about three 

 eighths of an inch square. A similar growth existed at the base of 

 the neck. In the lumbar region was a circular, granulating, bleeding 

 wound surrounded by a zone, from which the feathers had fallen. 



Case 8. A five-year-old parrot, which for two years had belonged 

 to the woman who brought it. A horny growth had appeared on the 

 left wing, and somewhat later another had developed on the head. 



Case g. A five-year-old parrot, which had been in its owner's 

 possession for three years, and had been ill for five to six months. The 

 left side of the head behind the e3'e was the seat of a C3'lindrical, horny 

 growth, about three eighths of an inch in length, and one sixth of 

 an inch in thickness. 



Case 10. A parrot which had appeared ill for the previous five to 

 six months. Had been in its owner's possession for two years. On 

 the right side of the neck were two horny tuberculous growths, about 

 three eighths of an inch in length. In the subcutaneous connective 

 tissue, covering the larynx, were two growths the size of a small hazel- 

 nut. The right wing showed an ulcerated tuberculous patch. 



Case ii. A parrot which had belonged to the same person for the 

 previous eighteen months. About three months before its appearance 

 here a growth of fibrous consistence which granulated freely, and the 

 centre of which was occupied by caseous material, had appeared on 

 the carpal region of the left wing. 



Case 12. Parrot ill for about six months. Horn}- growth on right 

 wing over the humero-radial articulation. 



Case 13. Parrot affected for the previous two months with an 

 ulcerated tuberculous swelling of the metatarsal region. 



Case 14. Parrot affected with two swellings the size of hazel-nuts 

 on the lower part of the right claw. The muscles of the claw were 

 atrophied, and the animal could not use the limb. 



Case 15. Parrot showing a horny tumour of conical form at the 

 base of the tail. This growth, which had only been discovered ten
