tal end of the hind legs and may spread to other portions of the 
body. It occurs in cattle which have been fed with large quanti¬ 
ties of potatoes, especially with potato mash, raw potatoes or 
potato plant. The active agent is believed to have been found in 
the noxious principles contained in the potato plant, or evolved 
from it in the preparation of the mash (solanin, fusil oil, organic 
acids, large quantities of potash salts); but we have as yet no 
certain knowledge in this respect. 
A malady analagous to schlempemauke has been observed 
after the use of grapes as food ( Traubenkammkrankheit .) 
3. In the sheep eczema appears as: 
a. Schwindflechte (false scabies). —A papular eczema, with 
subsequent desquamation of the cuticle, appearing by predilection 
upon the neck. 
b. Maulgrind (Maulraitde). —A circumscribed vesicular ecze¬ 
ma, which rapidly becomes crustaceous and is seen in young ani¬ 
mals in the vicinity of the mouth. 
c. Regenfaule ( wet Raiide). —In consequence of continuous 
rains, sheep exposed in the fields suffer from a softening of the 
epidermis of the skin of the upper parts of the body. There 
develops in consequence thereof a simple eczema, which usually 
runs a regular course, and may be followed by a not inconsider¬ 
able loss of wool.

4. In the pig eczema is seen as : 
Rufs (. Pechraude). —This is a pustular eczema, which soon 
goes over into the stadium impetiginosum, is usually chronic in 
its course, and is dependent ultimately upon a scrofulous dyscrasia. 
5. In the dog eczema appears in the most varied forms upon 
the back, head, neck, outer surfaces of the extremities, etc. It is 
especially old and well-bred dogs (Pinscher, Leonberger, Jagd- 
hunde)which are subject to eczema; and perhaps this has led to 
the idea that eczema canis is a constitutional disease, of which the 
skin malady is only a symptom ; very much as inflammation of 
the joints is an external symptom of gout. But the theory is as 
little proven as is that other one which would make eczema of 
dogs of mycotic origin. We will make no mistake if we say that 
eczema canis per se is a purely artificial malady; but that with
