ERYTHEMA, 311 
It must now be plainly evident that the writer considers follicular mange a 
malignant disease after it has once fairly started, and one that demands the 
most energetic treatment. 
If under either form of treatment advised the eruption is disappearing, the 
same evidently successful method should be persisted in, not forgetting the 
bathing, from tip to tip, with benzin, which is to help prevent the disease from 
spreading, and which, as previously recommended, should occur twice each 
week. And even did a cure take place, the entire treatment should be applied 
for a month thereafter, against a recurrence. 
If in any case a gain is not effected by treatment within two or three weeks, 
the case can rightly be considered hopeless, and of course the victim should be 
then destroyed. 
ERYTHEMA. 
Erythema is an inflammation of the skin which has various forms, but the 
most common, and only one that can be considered here without inviting con- 
fusion, is that of red patches of variable shape and size. These fade on pres- 
sure, there is little or no swelling, pain, or disturbance of the general system, 
and only slight itching. 
The eruption is really no more than a simple congestion, and the redness 
of the skin is identical with that produced by a mustard-plaster or other like 
irritant. 
It usually forms suddenly, and may as quickly disappear without leaving any 
trace; or the skin may burst, a watery discharge follow, and crusts form. 
All parts of the body are liable to be attacked, but the head and extrem- 
ities are commonly affected. 
The causes of this affection are many, and include gastric and intestinal 
disturbances, uncleanliness, want of proper grooming, long and matted hair, 
extremes of heat and cold, poor food, etc. 
Medication is scarcely necesssary ; for if existing derangements or disorders 
are overcome and errors in management corrected, the trouble will generally 
at once disappear. For example, among the most common sufferers are long 
haired, overfed and indolent house-pets, the eruption appearing as soon as the 
weather is very warm. Here the cause is evident, and if removed by clipping 
the hair, the erythema as a rule promptly fades.
