was continued at a quarter letter rate, and became (for 1 loth Zollgewicht = 1⅛ loth Prussian)—
| Up to | 10 | German miles | ¼ sgr. |
| 10 to | 20 | " | ½ sgr. |
| Over | 20 | " | ¾ sgr. |
With the exception of the name and address of the addressee no writing was permitted on these packets, but by the order of the 29th May 1848 the writing of the name and address of the sender and the date was permitted.
With the increase in the number of packets sent under band at the reduced rate, there grew up an increasing abuse of the privilege by the enclosure in such packets of written communications. In order to check this, it was provided in 1843 that when any large number of such packets were posted by the same person, a few of the packets should be examined in the presence of the sender. No penalty was at first imposed; but in 1850 it became necessary to take action, and the royal order of the 12th June 1804, prescribing a penalty of 10 thalers in cases where a letter was enclosed in a packet passing at a rate less than letter rate, was made applicable to the case of packets sent under band; and the regulation of the 15th December 1821, prescribing a surcharge of ten times letter rate for a packet of like weight, was made applicable to cases where a communication was written on the printed sheet sent at the reduced rate.[478]
In 1850, when the German-Austrian Postal Union was founded, a uniform rate of 4 silverpfennigs for each loth was introduced for packets sent under band. Following the establishment of the Union, the Prussian administration (§ 50 of law of 5th June 1852) fixed a uniform rate for its own service of 6 silverpfennigs for each loth. For local packets sent under band (Stadtpost-Kreuzbandsendungen) a rate of 1 sgr. for each packet was introduced, reduced to 4½ pf. for each packet when as many as 100 packets were posted at the same time, or 6 pf. each when from 25 to 100 were posted at one time. The definition of printed matter entitled
to the privilege[479] was now enlarged.[480] The penalty for misuse of the privilege was made a surcharge of four times the amount of the postage, but not less than 5 thalers, which might be increased fourfold on repetition of the offence. In 1854 the maximum charge for packets sent under band was fixed at six times letter rate, in order to get rid of the anomaly of a higher charge on heavy packets sent under band than on letters.[481] The fact that packets under band could be sent for 4 pf. throughout the territory of the Union, but that for transmission within the Prussian territory the charge was 6 pf., and that in consequence Prussian commercial men were posting their packets abroad in large numbers, led to a reduction of the rate in 1856 to 4 pf. for each loth.[482]
The large increase of traffic which resulted made desirable a simplification of the definition of packets entitled to the privilege. Only communications of general application could pass, and the officials found themselves often in doubt as to the application of the existing definition. Thus, notices of the despatch of goods, invitations, or printed letters could not be sent at the privileged rate, while, e.g., notices of marriages could. So far as the Union was concerned, in 1860 the privilege was limited to documents reproduced by mechanical means.[483] The maximum limit of weight was reduced from 16 loth to ½ pfund (15 loth). This definition was introduced in the Prussian inland service in 1861. The rate of postage was also modified in that year. The rate of 4 pf. for each loth was retained, but with the proviso that the charge on packets sent under band should not exceed twice letter rate. This effected a great reduction of charge for the heavier packets. Whereas previously the rate for a packet under band weighing 10 loth, sent more than 10 German miles, had been 18 sgr., it now became 6 sgr.[484] In 1865 a special rate of 4 pf. for printed matter sent in the form
of an open card was introduced in Prussia.[485] The simplification of definition and reduction of rate resulted in a large increase of traffic.
In 1867, when the North German Postal Services were unified, the penalty for abuse of the privilege was reduced to a surcharge of four times letter rate, but not less than a thaler; and the law of 1871, founding the Imperial Post Office, abolished the fine because it had been found that the offences were for the most part committed through ignorance of the regulations. Slight changes were made in the regulations under which printed matter was admitted to the privilege, but no change was made in the rates of charge.
The law regarding the Imperial Post Office (28th October 1871) left the fixing of rates for printed matter to the Imperial Chancellor. The maximum limit of weight was raised from ½ pound (250 grammes) to 1 pound (500 grammes). The rates of postage were ⅓ sgr. for each 40 grammes up to 250 grammes, with a maximum of 2 sgr.; from 250 to 500 grammes, 3 sgr.[486] The large increase of traffic resulting from the reductions in the rates for printed matter and for samples caused practical difficulties, and in 1873[487] the acceptance of letters, postcards, printed matter, and samples was to be only in the Briefkasten.
