An important advance in surgery
the successful substitution of catgut,
ivory and bone for defects in bone,
muscles and nerve sinews-was illus
trated by Prof. Gluck at the surgical
congress at Berlin. The inserted ma
terial sucks up the juices OF the body,
establishing the junction of the sepa-
rated ends without any shortening of
the part. Prof. Gluck presented cases
in which mobility had been restored to
defective fingers-a hitherto impossible
feat-by insertions of from two to four
inches of catgut; case in which the re-
moval of tumor from the thigh had
left defective bone, which was reme-
died by the insertion of ivory, shorten
ing being prevented; and case in which
a large piece of nerve in the groin had
been replaced with catgut, with no
serious impairment of functions.-Ar-
