Century Dictionary and Cyclopedia
- n. In postal service, a slip of paper accompanying each package of letters, showing the destination of the package, the point of departure, the date, and the name of clerk sending it.
“Special Delivery letters (unregistered) number five or more for any one office the Postmaster should make a separate package of them, marking it "For Special Delivery"; if such letters are fewer than five, he should place them immediately under the "facing-slip" of the letter-package which he makes up, either directly or indirectly, for the Special Delivery office for which they are intended, so that the most prompt attention may be secured therefor.”
