(_c_) The postage on book-packets must be prepaid, and that by postage-stamps affixed outside the packets or their covers. If a book-packet should be posted insufficiently prepaid, it is forwarded, charged with the deficient book postage together with an additional rate; thus, one weighing over four ounces and only bearing one penny stamp, would be charged twopence additional postage on delivery. If a book-packet is posted bearing no stamps at all, it is charged as an _unpaid letter_. (_d_) In cases where a book-packet is re-directed from one to another postal district in the United Kingdom, the same charge is made on delivery as was originally made for the postage, one penny for four ounces, twopence for a packet under eight ounces, and so on.
