Cattses. — Anything which 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. 



Tkeatmeis't. — 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. 



Beyonia. — Aesenicum. — I have found Bryonia to be a 

 remedy of great value in this disease, especially in its idio- 

 pathic forms. Use it in 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. 



NiTEic Ayn MuEiATic Acids. — Por instructions as to the 

 use of these remedies, see page 184. 



Ammonia Citeate op Ieoit. — 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. 



Sesquichloeide of Ieon. — Sometimes this latter prepa- 

 ration of Iron acts better than the Ammonia Citrate. Grive it 

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

 may be given night and morning. 



Cold "Watee Bakdages. — Apply bandages, dipped in cold 

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