Acute Lymphangitis of Plethora in Horse. 543 



sy of the limb by the acute fever, the great local tenderness 

 especially of the inguinal glands, and by the tender corded 

 lymphatics that enter these. From cutaneous glanders (farcy) 

 it is diagnosed by the more acute fever, by the swelling of the in- 

 guinal glands in the early stage of the disease, followed by the 

 swelling of the lower limb, and by the absence of the hard, com- 

 paratively insensible and prone to ulcerate, farcy bud. Farcy 

 buds usually appear on the pastern or fetlock, with more or less 

 swelling of the lower part of the limb, while the inguinal glands 

 are as yet normal in size and without tenderness. From erysip- 

 elas, with which this has been confounded, it is distinguished, by 

 the suddenness of the onset, under the circumstances above de- 

 scribed, by the high type of fever, by absence of early cutaneous 

 inflammation and the formation of vesicles, and by the fact that 

 lymphangitis commences in swelling of the inguinal glands. 



Treatment. In cases that are seen in the earliest stages, before 

 the leg has become badly swollen, recovery will usually take place 

 under active exertion continued for hours at a time. The pump- 

 ing action inside the hoof during exercise, and the alternate com- 

 pression and relaxation of the lymph vessels by the muscles, tend 

 to establish a rapid current of lymph, to break up coagula and to 

 re-establish a healthy condition. Friction from below upward on 

 the lymphatic vessels and swollen limb will greatly assist in this 

 restoration. Different agents are employed, such as camphorated 

 -spirits of oil, iodine, mercurial, and even blistering ointments. 

 These should not replace exercise when this is possible. 



When the fever has set in suddenly and runs very high, the 

 abstraction of four or five quarts of blood, and the administration 

 of a purgative (8 drs. aloes) will be in order. In cases occurring 

 in the same stable and in all other respects apparently identical, 

 the subjects of phlebotomy recovered without any permanent 

 swelling of the limb, while those that were not bled recovered 

 with thickened limb. 



In cases so advanced that the limb cannot be used, cold irriga- 

 tion, with friction, may be applied, and when the irrigation is 

 intermitted one may apply some astringent (vinegar, alum, lead 

 acetate), or an iodine lotion followed by an evenly applied bandage. 



The purgative should be followed by full doses of diuretics
