From cutaneous strangles it is again distinguished by the 

 rapidity of its appearance, progress and subsidence, by the com- 

 parative absence of fever, of nasal discharge, and of submaxillary 

 swelling, and by its indisposition to form purulent centres. Nor 

 is it confined to solipeds that are young and still susceptible to 

 strangles. 



'Brova. petechial fever \\. ^\Ss.rs in the absence (usually) of the 

 predisponent disease (strangles, influenza, etc.), of the marked 

 toxsemic prostration which accompanies the latter ; of the pre- 

 sence of the early petechise, punctuate or in patches, on the 

 pituita, and other visible mucosae and on the skin as a precursor 

 or coincident of the nodules ; of the early and free serous or 

 bloody oozing from the nodules ; of their marked disposition to 

 persist ; of their predilection for the limbs and dependent parts 

 of the trunk ; and of their tendency to form extended chshions 

 and sloughs. 



From the eruption caused by green alfalfa and other legumes it 

 it is distinguished by its very rapid evolution and equally speedy 

 disappearance, by the much larger size and flattened surface of 

 the individual nodules, by the absence of the focus of suppura- 

 tion and of the resulting open sores. 



From swine erysipelas (rouget) the distinction is clear in the 

 absence of the characteristic fever and prostration, in the presence 

 of a common, usually alimentary cause, and in the absence of all 

 indication of infection. The malady lasts from forty-eight hours 

 to five or six days and usually ends in recovery. 



Treatment. As the fundamental cause of the disease, the in- 

 dividual or racial susceptibility, is a constitutional condition, 

 usually beyond the reach of medicine, attention must be given 

 to the immediate or exciting causes of the malady. The vege- 

 table local irritants and animal venoms must be guarded against 

 or treated, by soothing measures or antidotes. Special care 

 should be exercised at the period of moulting, in spring, and 

 during the heats of summer. Careful grooming, and a moderate, 

 laxative, non-stimulating diet will be of value. But above all 

 attention must be given to the elimination of the irritant pro- 

 ducts of intestinal fermentation. In the pig or dog this may be 

 largely accomplished by emetics, such as a teaspoonful of ipe- 

 cacuan wine. In all animals aperients may be given and as a rule
