227. CRAYFISH BROTH, FOR PURIFYING THE BLOOD.
TAKE two pounds of the lean part of very white veal, cut it into
small pieces, and pound it well in a mortar; to this add three dozen
crayfish and a handful of green chervil, and pound these together so
as to thoroughly bruise the crayfish. Then remove the whole into
a stewpan, and pour upon it three pints of cold spring water, add a
little salt, and place the stewpan on the stove to boil; after which
set it by the side of the stove-fire, and keep it gently simmering for
three-quarters of an hour; it may then be strained through a nap-
kin for use.
This kind of broth, in order to promote the desired effect, should
be taken by the convalescent upon an empty stomach.
