I02 CLINICAL VETERINARY :\IEDICINE AND SURCERY. 



On the 23rd July, 1895, a small bitch belonging to M, L — , Rue de 

 Charenton, Paris, was brought for examination. 



For about six weeks this bitch had shown, nearly over the centre 

 line of the front of the neck, two sinuous wounds. During the journey 

 from Paris to Alfort the child who brought it had bandaged the animal's 

 neck with her handkerchief, and in our presence she wiped away the 

 pus running from the wounds with this same handkerchief. 



The appearance of the wounds, the thinness of the patient, and the 

 dyspnoea, awakened suspicion of tuberculosis. I made co\'er-glass pre- 

 parations with the pus ; all contained bacilli. 



This animal was left, and kept in the stable belonging to the surgical 

 clinique. Five months later it died from generalised tuberculosis. 

 The sinuses never healed. 



On the i6th May last, M. H — -, living in the Rue St. Martin, Paris, 

 brought us a four-3'ear-old dog, which had suffered for three months 

 from an ulcerous wound one and a quarter inches in length and three 

 quarters of an inch in width about the middle of the neck. The margins 

 were separated from the skin, eroded, and covered with crusts and 

 blood-stained pus. Four inches below this lesion was a slender sinus 

 masked by the agglutinated hair. As in the cases just mentioned, pus 

 from these lesions was found to contain large numbers of bacilli. 



Until the day it was brought to Alfort this dog lived in a corner of 

 the single room inhabited by M. M — , his wife, and their child. 



These tuberculous wounds of the neck are of lymphatic origin. 

 Only one case had been published pre\ious to my researches, and the 

 author, Miiller of Dresden, regarded the case as of primary cutaneous 

 origin. I have been able to follow the development in several subjects. 

 It is similar to that of tuberculous suppurating adenitis in man, and 

 exhibits three principal stages: (i) Glandular disease; (2) Abscess 

 formation in, or around a lymphatic gland ; (3) Ulceration of the skin. 

 When a lesion of this kind is fully developed, or has existed for some 

 weeks, it usually presents the following appearance : A circular, oval, 

 or irregular wound, the margins of which are denuded of hair, torn or 

 thinned, and separated from the subjacent tissues; with reddish, 

 uneven base covered with indolent granulations, or dotted over with 

 yellowish points, from which sinuous tracts lead towards the trachea, 

 or along the line of adjacent vessels. The wound discharges greyish 

 or blood-stained pus, always purulent, and sometimes rich in bacilli. 



Their true nature not being recognised, these lesions are treated 

 like simple wounds; they continue to suppurate. In certain patients
