504 asKEEAL DISEASES. 



lymphangitis appear round the affected part in and immediately 

 under the skin. These abscesses form nodular new-growths which are 

 seen later on in the lymph glands, connective tisue of the muscles, 

 bones, and even in the conjunctiva, and which undergo a slow 

 process of suppuration. In the skin they subsequently change 

 into fungoid ulcers. The mortality amounts to about 10 per cent. 

 With energetic treatment, a cure takes place in from one to seven 

 months'^ {Friedberger and Frohner). A well-marked feature of 

 this disease is the presence of prominent and hard lymphatic vessels. 



Dr. Lingard gives the following intereisting account of symptoms 

 which he observed in cases of this disease : — 



" The patient (a mule) presented a chain of abscesses connected 

 by corded lymphatics starting from the shoulder and running up 

 the neck following the course of the jugular vein. This animal 

 Avas destroyed. Local lesions only, all internal organs presented a 

 perfectly healthy appearance. 



" Mule. Fluctuating swellings were observed running up the 

 inside of the arm. Destroyed. Local lesions, internal organs 

 healthy. 



" Mule. This animal presented several small fluctuating tumours 

 on the right side of the chest, over the ribs, and a thick corded 

 lymphatic proceeded from the root of the neck and ran down 

 between the fore legs, from before backwards along the under 

 surface of the abdominal wall. Destroyed. Local lesions, internal 

 organs presented a perfectly healthy appearance." 



He found four horses and nine mules " presenting small tumours 

 and open wounds on different parts of the body, associated in some 

 instances with swellings varying in size from a small walnut to 

 that of a hen's egg, from which corded and beaded lymphatic 

 vessels issued. Whilst in others, tumours were observed which 

 on manipulation were found hard and fluctuating according to the 

 stage which they had attained. In the majority of cases the 

 lymphangitis had made its appearance on a level of a pre-existing 

 wound of little importance, abrasion of the skin, or harness gall, 

 etc., which had healed for some time, may be for months, and had 

 broken out afresh on the original site, or pustules appear in close 

 proximity to the cicatrix. In more advanced cases, considerable 

 areas of the skin covering the ribs, front of the chest, side of the 

 head or limbs were involved, and one animal presented a fair-sized 

 ulcer (as large as a six23enny piece) on the nose." 



Cadiot and Kies remark that tubercles are never found in the 

 lungs of animals affected only by this disease.

 in India, Dr. Lingard states in his " Annual Report" for 1900-1901,
