Letters.

Letters which it is desired to protect against unauthorized opening (by moistening the pasted portion) may be securely sealed by using a solution of oxide of Copper in ammonia as paste. When applied to the paper it dissolves the cellulose, and on drying, the two surfaces adhere Indissolubly together. Even monkeys coming to talk won't throw any additional light on the buzz-saw business. Monkeying with that speaks for itself.
