mal Avill permit, are most useful, but in the majorit}' of cases the 

 stupefied animal is unable to )>e moved satisfactorily or to have one 

 foot lifted for local treatment, and the only treatment consists in lo«il 

 bleeding above the coronary bands and the application of poultices. 



During convalescence small doses of alkalines may be kept up for 

 some little time, but the greatest care must be used, while furnishing 

 tlic animal with plent}' of nutritious, easily digestible food, not to over- 

 load the intestinal tract, causing constipation and consequent diarrhea. 

 Special care must be taken for some weeks not to expose the animal 

 to cold.

Anasarca, or purpura hemorrhagica. — A previous attack of inllu- 

 enza is a common predisposing cause of this disease which appears 

 most frequentl}^ a few weeks after convalescence is established. It 

 occurs more frequently in those animals which have made a rapid 

 convalesccncG and are apparentl}^ perfectly well than it does in those 

 which have made a slower recovery. 



Anasarca commences by sjnnptoms which are excessively variable. 

 The local lesions may be confined to a small portion of the aaimal's 

 bod}' and the constitutional phenomena be nil. The appearance and 

 gra\'ity of the local lesions may be so unlike, from difference of loca- 

 tion, that they seem to belong to a separate disease, and complications 

 ma}' completel}' mask the original trouble. 



In the simplest form the first sjniiptom noticed is a swelling, or sev- 

 eral swellings, occurring on the surface of the bod}' — on the forearm, 

 the leg, the under surface of the belly, or the side of the head. The 

 tumefaction is at first the size of a hen's egg; not hot, little sensitive, 

 and distinctly circumscribed by a marked line from the surrounding 

 healthy tissue. These tumors gradually extend until they coalesce, and 

 in a few hours we have swelling up of the legs, legs and belly, or the 

 bead, to an enormous size; they have always the characteristic con- 

 stricted border, which looks as if it had been tied with a cord. In the 

 nostrils are found small reddish spots, or petechise, which gradually 

 assume a brownish and frequently a black color. Examination of the 

 mouth will frequently reveal similar lesions on the surface of the tongue, 

 along the lingual gutter, and on the f ra^num. If the external swelling 

 has been on the head, the petechine of the mucous membranes are apt 

 to be more numerous and to coalesce into patches of larger size than 

 when the dropsy is confined to the legs. The animal may be rendered 

 stifl" by the swelling of the legs, or be annoyed by the awkward swollen 

 head, which at times may be so enormous as to resemble that of a hip- 

 popotamus rather than that of a horse. During this period the tem- 

 perature remains normal; the pulse, if altered at all, is only a little 

 weaker; the respiration is only hurried if the swelling of the head
