By the taste.

NOTE.

For writing by the taste, it will be necessary to immerse an equal number of the pegs or beads in weak solutions of alum, aloes, common salt, or any other liquid whose taste is sufficiently pungent or aromatic, to be distinguished when dry, on applying the tongue to them for that purpose.
