(a) Lay the writing in a shallow dish, and pour skimmed milk upon it. Any 6pots not wet at first may have the milk placed upon them lightly with a feather. When the paper is wet all over with the milk, take it up and let the milk drain off, and remove with the feather the drops which collect on the lower edge. Dry carefully.

(6) Prepare water-starch, in the manner of the laundress, of such a strength as to form a jelly when cold, and then apply with a broad camel-hair brush, as in varnishing.

(c) The same may be done with thin, cold isinglass water or size, or rice water.
