Note 613 — VII AN ANALYSIS OF COST
Reading edition
In London there are the following divisions:—
(1) "Short Letters" (including postcards and a large proportion of the halfpenny packets). Halfpenny packets which are of such size as to admit of handling with the short letters are referred to as "short halfpenny packets."
(2) "Long Letters" (for the most part letters of foolscap size).
(3) "Circulars" (that is, packets sent at the letter rate or by the halfpenny packet post, posted in large numbers at one time and generally of uniform size but which cannot conveniently be dealt with at the ordinary letter-sorting frames).
(4) "Packets" (that is, packets which are bulky or of irregular shape and cannot therefore be sorted at the ordinary sorting frames).
(5) "Newspapers."
