ULCEKATIVE LYMPHANGflTlS. 505 



" that experiments conducted at Muktesar have shown that a cure 

 can be affected 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 develop- 

 ment of the disease loooupies several months, this measure can 

 easily and usefully be adopted in the case of valuable remount 

 animals.'^ 



The surgical treatment of epizootic lymphangitis consists of 

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

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



Ulcerative Lymphangitis. 



NATURE AND CAUSE.— In the " Annales de Tlnstitut Pasteur" 

 for November, 1896, Nocard describes a form of lymphangitis, 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 Rivolta's epizootic lymphangitis (p. 503), 

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

 by a microscopical examination of its disease-producing or- 

 ganisms. 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 which are generally 

 placed parallel to each other, although sometimes they may be ar- 

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

 the fact that they stain by Gram's method, which is a means of 

 differentiation that can be employed only by persons who are con- 

 versant with bacteriology. The special organism of epizootic 

 lymphangitis is more or less oval in form (p. 503). 



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

 the hind being more commonly affected than the fore. The lym- 

 phatic vessels of the suft'ering limb swell and form abscesses which 

 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 weight on it, or even 

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

 will cause the jDatient great pain. Abscesses and consequently 

 ulcers may form on the lower part of the body. Sometimes the 

 abscesses and the corded condition of the lymphatics disappear 

 and the ulcers heal up in the summer, only to come on again during 

 the next cold weather. Recovery may take place spontaneously, 

 or the attack may continue for several years. Nocard lays great 

 stress on the fact that in all the cases which he has seen, the 

 Imyphatic glands of the groin of an affected limb never became
