_Worm in Books_ (Vol. viii., p. 412.).--ALETHIS is presented with the
following recipe from a very curious old French book of receipts and
secrets for everything connected with arts and trades. Put some powdered
colocynth into a phial, and cover the mouth with parchment pierced with
holes. With this the books should be powdered, and from time to time beaten
to drive out the powder, when the same process must be repeated.
