lies next within the shells of eggs." We know that this membrane is
very tough, (and very indigestible). Dr. Amat orders that " six, or
eight strips of the said membrane, (quite fresh of course), shall be
applied over the raw flesh of a wound, a burn, or an open sore, and
then covered with a small square of Tin-foil—a little beyond the
margins of the wound,—this being fastened on (as already stated) with
an antiseptic bandage. After four days the bandage and Tin-foil are to
be removed; when it will be found, (it may be hoped), that the
egg-membrane has partly grown into the sore tissues, so as to be
causing the formation of a new skin. The membrane does not always
adhere ; but when it can be made to do this, the process of
closing-over (cicatrisation) is hastened ; and not only so, but the
wound, or sore, heals exceptionally well, leaving but few perceptible
traces behind. It may be plausibly supposed that the Sulphur which is
known to form an infinitesimal constituent of this egg-membrane, helps
materially to promote such speedy, and sound healing.
As
a remarkable fact eggs are associated by the Jews with funerals, being
eaten during the eight days of mourning. A hard-boiled egg is always
laid on the supper table of the modern Jewish Passover, together with
unleavened bread, bitter herbs, and a charred shank-bone of a lamb.
Similarly
as to the Sulphur, it is a matter of familiar experience, that to carry
a small raw potato in the trousers pocket is found to alleviate, or
prevent, chronic rheumatism in a person who is physically disposed
thereto. This salutary effect is due likewise to the sulphur contained
in the said tuber, mainly in its skin. When a potato is peeled, as
every one knows, its raw cut surface
