492 GENERAL DISEASES. 



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

 broken out afresh on the original site, or pustules appeared in 

 close proximity to the cicatrix. In more advanced cases, consider- 

 able 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 sixpenny piece) on the nose. 



Tubercles are never foimd in the lungs of animals affected only 

 by this disease. 



TREATMENT. — With reference to the occurrence of this disease 

 in India, a cure can be effected by removing animals to a high 

 level, 7,500 feet elevation, a result which agrees with the fact that 

 the disease in Europe disappears above a given line of latitude. 

 As the development of the disease occupies several months, this 

 measure can easily and usefully be adopted in the case of valuable 

 remount animals. 



The surgical treatment of epizootic lymphangitis cx)nsists of 

 opening the abscesses, cleaning and scraping them out, and freely 

 using strong antiseptics (p. 67) and the firing iron. 



Ulcerative liymphangitis. 



NATURE AND CAUSE.— In 1896, Nooard described a form of 

 lymphajigitis, the symptoms of which are similar to those of farcy ; 

 although patients affected only by it give no reaction to mallein. 

 In these two respects it resembles epizootic lymphangitis (p. 490), 

 from which, and also from farcy (glanders) it can be distinguished 

 by a microscopical examination of its disease-producing organisms. 

 These microbes, which are found in large numbers in the pus 

 issuing from a recently-opened abscess of this disease, are short 

 thick rods which have rounded ends and are generally placed 

 parallel to each other, although sometimes they are arranged in 

 lines. They differ from the rods (bacilli) of glanders by the fact 

 that tliey stain by Gram's method, which is a means of differentia- 

 tion that can be employed only by persons who are conversant with 

 bacteriology. The special organism of epizootic lymphangitis is 

 more or less oval in form (p. 490). 



SYMPTOMS. — The disease usually breaks out in one of the 

 legs ; the hind being more commonly affected than the fore. The 

 lymphatic vessels of the suffering limb swell and form abscesses 

 winch on bursting give rise to deep, unhealthy-looking ulcers on 

 the inside and sometimes on the outside of the leg, which may 

 become swollen and the animal may not be able to put weieht on 

 it, or even allow it to rest on the ground. In such cases, pressure 

 on the limb will cause the patient great pain. Abscesses and
