tive effects are recorded for those which, when properly obtained, would 
be valuable acquisitions to our much needed therapeutics. 
“ In order to appreciate the value of a remedy,” says Headland, “ we 
must have: 1st, a proper understanding of the pathological condition 
to be overcome; 2d, a knowledge of the agent we employ.” The im¬ 
portance of these two rules is commensurate with the grounds they em¬ 
brace. 
Purpura hsemorragica, by most authorities, is classified among cuta¬ 
neous diseases, which, like its name, originated from a frequent symp¬ 
tom, cutaneous hemorrhage. It is not due to any special poison, nor to 
any organic trouble, hence it is not an exanthemata. * If the cutaneous 
hemorrhage was always a symptom, we could consider it a cutaneous dis¬ 
ease, but such is not the case. Again, we find other authorities who 
classify it under scorbutic affections (haematic), which is probably the 
most correct, in consideration that the blood presents the most lesions. 
If we accept purpura haemorragica as scorbutic, we must look to the 
blood for our etiology and treatment. 
In relation to the etiology of this disease, we have much yet to 
learn (which at once depreciates the value of therapeutic measures). 
From its classification, it should be traceable to an insufficient supply of 
alimentary principles contained in the food. Such is not distinctly true, 
since purpura haemorragica is most often met in isolated cases, whereas it 
should prevail as if it were an epizootic. Again, any special dietetic 
treatment avails nothing. Debility, induced by previous inflammatory 
disease, poor living, dripatluc , and last, if not least, v as o-motor-paralysis. 
The latter would appear a secondary consideration, superinduced by 
the morbid blood changes (believing the blood change to be the primary 
lesion), purpura haemorragica involves danger from loss of blood from 
the different outlets of the body, and extravagations into serous cavities, 
lungs, etc.. Exclusive of these sources of danger, recovery under judi¬ 
cious treatment may be expected. The objects of treatment in cases of 
purpura haemorragica, are the restoration of the normal constitution of 
the blood, increase of vital powers, and restraint of hemorrhage. 
If we knew what the exact change or changes of the blood were, it 
would be easy to apply the proper remedies. 
Then we must do the next best thing, and that is, place the patient 
on the best treatment, both medical and hygenical, that is conducive to 
good blood and good health, namely, varied and nutritious diet, in small 
quantities, frequently repeated, good fresh air (roomy box), and, when 
possible, I think a little exercise excellent.
