DISEASES OF THE SKIN AMONG DOMESTICATED ANIMALS.

of the skin cause single stages to be easily overlooked. In many 
eczemas the papular merges at once into the squamous stage. 
Others again develop at once from a dermatitis erythematosa 
(see above). And in most cases the animals themselves obliterate 
the characteristic features of the disease. 
For eczema, especially in the more acute forms, is a fairly 
itchy malady and so incites the animal to rubbing and scratching 
that the deeper layers of the skin are soon involved in the inflam¬ 
mation. 
1. In the horse eczema is seen as: 
a. Schwindflechte (humid tetter).—A papular eczema, but sel¬ 
dom developing into vesicles, and generally passing directly into 
the desquamating stage; it is often seen at the time of the change 
of the hair. 
b. AT««^(Schmutzmauke, Schrendenmauke,—Grease).—This 
is an eczema occurring at the back of the fetlocks from injuries 
of various kinds. It is vesicular, but soon passes into the stadium 
madidans and the stadium crustosum. 
c. Raspe. —A chronic eczema, which develops from a derma¬ 
titis erythematosa and becomes squamous without going through 
the intermediate stages. It is distinguished by a considerable 
thickening of the skin. Its favorite seat is the inner surface of 
the knee of the anterior leg and the hock. 
d. Mahnengrind and Schweisgrind. —A pustular eczema, ap¬ 
pearing on the parts covered with long hair, the comb and the 
tail. It is usually overlooked for a long time, on account of its 
location, and hence important structural changes in the skin and 
permanent alopecia may take place. 
e. Kleinjlechte and Schuppenjlechte (Hungerraiide).—A slowly 
spreading squamous eczema, appearing by preference upon the 
head and around the root of the tail. The primary papular and 
vesicular stages do not usually occur. 
2. In cattle eczema occurs as Kleinjlechte and Schuppen- 
jlechte. But there is a form of Grease (see above) which is pecu¬ 
liar, and is known as: 
Schlernpemauke. —This is a simple eczema, which as a rule 
goes through all the stages of that disease. It begins at the dis-
