Special advertisement supplements were permitted to be sent by post together with newspapers by the order of 30th September 1871. These supplements in form or character must not be similar to the main newspaper. They must not be printed at the same office, and no charge might be made for their insertion. A special supplement must not exceed one sheet and must not be bound. The newspapers in which they were inserted must bear a notification to that effect in a prominent position. All copies of the supplement must be submitted to the Post Office and the postage paid in advance. They were then stamped at the office of posting, and if not posted within three days the postage might be forfeited. The rate for each supplement was 1/12 sgr.[398] The number of such supplements was not as great as was anticipated, the chief reason for which was that the postage was still too high and the regulations too complicated. In 1873 the rate was reduced to 1/2 pf. for each copy, with a reduction of 50 per cent. when as many as 7,200 copies were posted at the same time. The obligation to submit all copies to the Post Office for stamping, and the requirement to post them within three days thereof, were at the same time removed, and the simple obligation to give previous notice of posting substituted. The obligation to indicate on the newspapers that a special supplement was enclosed was also withdrawn. In 1874 the regulations were further relaxed. Special supplements were allowed to be printed at the same office as the newspaper, and charges for the advertisement might be made.[399] The limit of size was extended to two sheets, at which it remains.[400] In 1900 (20th March) the rate was changed to 1/4 pf. for each 25 grammes weight for each supplement. The number of special supplements in 1910 was 214 millions. * * * * * III THE RATE FOR PARCELS PARCEL POST IN ENGLAND
