neurotic curative action, which restores the vital processes to 
normal, at the same time favoring phagocytosis, whereby the 
general health becomes improved. The author adds that this 
special method of electric treatment cures and avoids the re¬ 
currence of the affection when applied in time. Further, he 
says, electricity remains the only applicable remedy in tumors 
of malignant character, which cannot be operated upon .—(Berl

The Use of Shele Membrane of Hens’ Eggs in Cover¬ 
ing Granulating-Surfaces [Prof, Schuller ].—Up to the 
present time, wounds in which the covering over with skin in 
a natural way was retarded, the method generally used was 
transplantation. But there are cases where it is impossible to 
graft skin from the patient, and also where it is impossible to 
use the skin from other persons. Jffor such cases the author 
recommends a compensation from the animal kingdom, which 
is always easy to procure in perfect and in an aseptic condition, 
and which is very easily applicable, containing undoubtedly 
epithelial material, and when used in the proper way for covering 
granulating surfaces depacts it in an extraordinarily easy man¬ 
ner. This is the shell membrane of a hen’s egg. The employment 
of the shell membrane is as follows: After breaking the fresh 
egg and the eversion of the contents, the membrane is quickly 
detached from the shell in as large a piece as possible; care 
should be taken not to touch or crush it, and then applied with 
the internal side (the one facing the white of the egg), to the 
granulating surface, which was previously cleansed and 
thoroughly dried. After this procedure it is secured by a 
simple dressing consisting of gauze and cotton. It is not essen¬ 
tial that the pieces of the shell membrane should cover or come 
in contact with the edges of the normal skin ; the principal 
point is the firm adherence to the granulating surface. Anti¬ 
septic powders or liquids are to be avoided, as they will injure 
the young epithelia. The wound must be in a thoroughly 
aseptic condition, all infection removed, and naturally the 
granulation must be complete. In changing the dressing, 'which 
the author generally does in four days and sometimes sooner, 
the shell membrane is easily detached, under which is noticeable 
a whitish or blueish white epithelial layer. The pieces cover¬ 
ing the edges of the skin generally adhere a little longer. This 
can be tried in veterinary practice, as there are many opportu¬ 
nities, especially among the smaller animals. — (Berliner
