Her Majesty's Mails

(f) A book-packet may contain any number of separate books or other publications (including printed or lithographed letters), photographs (when not on glass or in cases containing glass), prints, maps, or any quantity or quality of paper, parchment, or vellum. The whole of this description of paper, books, and other publications, may either be printed, written, engraved, lithographed, or plain, or the packet may consist of a mixture of any or all these varieties. The binding, mounting, or covering of books and rollers, &c. in the case of prints or maps, are allowed. In short, whatever usually appertains to the sort of articles described, or whatever is necessary for their safe transmission, may be forwarded through the post at the same rate charged for the articles themselves. (g) Among the general restrictions, we find the following:-- No book-packet must exceed two feet in length, width, or depth. No book-packet must contain anything inclosed which is sealed against inspection, nor must there be any letter inclosed, or anything in the way of writing in the packet of the nature of a communication, either separate or otherwise. Entries on the first page of a book, merely stating who sends it, are allowable (and even desirable in case of failure of delivery) inasmuch as they are not regarded as of the nature of a letter. Any packets found with a communication written in it (if the communication in question cannot be taken out, but forms a component part of the packet) will be charged with the unpaid letter postage, and then sent forward.
