GENERAL, CONTAGIOUS, AND ENZOOTIC DISEASES. 273 



farcy is the development of glauders in an acute form, with all the char- 

 acteristic lesions in the nasal chambers, glands, and air-passages. 



Chronic farcy is not usually accompanied by the same degree of con- 

 stitutional disturbances as the other forms of equina. Circumscribed swell- 

 ings appear generally in those parts of the body where the skin is thin- 

 nest; the changes which occur in these tumors are the same as those 

 described in acute farcy. The lymphatic glands are inflamed and swollen 

 and form a corded network in the skin. 



The physical appearances and characters of these * cords,' or inflamed 

 lymph-vessels, are not always precisely similar. Generally of the thick- 

 ness of a goose-quill, they are rarely, either in their bulk or the uniform 

 resistance or tension of the swelling, continuously alike. At irregular 

 points along their course, usually at the situations of the so-called valves, 

 there are dilatations or small- circumscribed spots of induration and ele- 

 vation of tissue, which have not inappropriately been likened to a string 

 of beads or pearls. When these small indurated swellings are fairly de- 

 veloped they do not often disappear, but, like the primary farcy bud, 

 gradually take on ulterior changes, terminating in central softening and 

 discharge of puriform material. These smaller buds further comport 

 themselves in a precisely similar manner to the larger ones, by widening 

 through ulceration, and ultimately coalescing, thereby forming not 

 merely an ulcerous sore, but an ulcerous sinuous tract or cavity; these 

 unhealthy secreting sinuosities have generally been known as 'farcy- 



Treatment. — No known methods of treatment avail to do more than 

 prolong life. An animal in wliich either glanders or farcy is suspected 

 should be at once isolated, and as soon as the disease is clearly manifested, 

 it is best to be destroyed at once. 



ERYSIPELAS. 



Definition. — A specific febrile disease accompanied by inflammation 

 of the skin and subjacent tissues, followed by swelling which usually 

 spreads rapidly, by an eruption, and by pain. 



Etiology. — Weak and exhausted animals are most subject to it. It 



generally succeeds wounds of the legs. 



Symptoms. — The symptoms of erysipelas are thus stated by Kobin-
