Kelly's Post- Office Directory. (Kelly and Co.)—This valuable requisite for

the counting-house and for business has this year been subjected to an entire revision. Additional cross-references and aids to search have been added, in such a manner as enables persons who refer to its pages to find the addresses they require in an instant. The whole of the " Commercial" portion has been re.sot in smaller, yet perfectly clear type, thus allowing nearly all the Christian names to be printed in full; 186 new trades have been added, and the " Streets " portion so re- arranged that the stranger or visitor may find his or her way to the most obscure portion of the metropolis. The new Map of London, again, is folded in such a manner that any part may be referred to without unfolding the whole.
