Causes. — Anything wHch debilitates, or lowers the tone 

 of the vital energies, predisposes the organism to the develop- 

 ment of Purpura — such as exposure of the animal to cold and 

 wet; poor, scanty diet, especially in association with severe 

 labour, and continued exposure to cold and wet. Scarlatina is 

 a cause of Purpura ; also that peculiar state of the respiratory 

 organs produced by, or associated with, Chronic Cough. 



Teeatmeht. — The best remedies, in general, are — Bryonia 1, 

 Nitric and Muriatic Acids, Arsenicum 3, Ammonia Citrate of 

 Iron, Sesquichloride of Iron ; and Cold Water Bandages and 

 Scarifications. 



Bryonia. — Arsenicum. — I have found Bryonia to be a remedy 

 of great value in this disease, especially in its idiopathic forms. 

 Use it ia 2-drachm doses of the 1st dilution, mixed with 3 or 4 

 ounces of water. The doses may be repeated three or four 

 times a day. It may either be given alone or in alternation 

 with Arsenicum, of which use the latter in 2-drachm doses of 

 the 3rd dilution,- mixed with 2 or 3 ounces of water. 



Nitric and Muriatic Acids. — For instructions as to the 

 use of these remedies, see page 184. 



Ammonia Citrate of Iron. — This is a remedy of great value, 

 if used during the convalescent stage of the disease. Give it 

 in 2-drachm doses, repeated three or four times a day ; each 

 dose should be mixed with 6 or 8 ounces of water. It improves 

 the condition of the blood. 



Sesqidchloride of Iron. — Sometimes this latter preparation 

 of Iron acts better than the Ammonia Citrate. Give it in 

 2-drachm doses, mixed with 5 or 6 ounces of water. A dose 

 may be given night and morning. 



Cold Water Bandages. — Apply bandages, dipped in cold 

 water, freely to the swollen Kmbs ; soft twisted hay-bands will
