Telegraph Companies, the number of its employés is greatly increased. The postage charged on foreign and colonial letters is too small to pay for the mail-packets and other expenses; profit is derived only from the inland letters. There are now in London and the suburbs about 730 pillar-boxes and wall-boxes; without counting receiving houses. Newspapers and book packets must not be put in town pillar-boxes. A very useful novelty, _Post Office Savings’ Banks_, was introduced in 1861. In the year 1840, in which the uniform rate of one penny per letter of half an ounce weight, &c., commenced, the revenue of the Post Office was only £471,000. Its revenue received during the year 1871–72 was no less than £6,102,900, and every year the receipts are increasing. New postal buildings of great extent have been erected on the opposite side of the street. THE CORPORATION; MANSION HOUSE; GUILDHALL; MONUMENT; ROYAL EXCHANGE. It will be convenient to group here certain buildings belonging to the Corporation of London; and to prefix to a notice of them some account of the mode in which the city of London is governed. The Corporation.—With respect to civic jurisdiction, the city of London is governed in a peculiar manner. In virtue of ancient charters and privileges, the city is a species of independent community, governed by its own laws and functionaries. While all other boroughs have been reformed in their constitution, London has been suffered to remain, as yet, in the enjoyment of nearly all its old usages. The city is civilly divided into twenty-five wards, each of which has an alderman; and with one alderman without a ward, the number of aldermen is 26. Each is chosen for life, and acts as magistrate within his division. The freemen of the various wards elect representatives annually to the common-council, to the number of 206 members. The lord mayor, aldermen, and common-council, compose the legislative body for the city. The lord mayor is chosen by a numerous and respectable constituency, called _the livery_, or liverymen; these are certain qualified members of trading corporations, who, except in electing the lord mayor, sheriffs, members of parliament, &c., do not directly interfere in city management. The Court of Aldermen and the Court of Common-council have certain legislative and executive duties, partly with and partly without the immediate aid of the lord mayor. The revenue of the city corporation is derived from sundry dues, rents, interest of bequests, fines for leases, &c. The magistracy, police, and prisons cost about £40,000 annually; but this is exclusive of large sums disbursed by the court of aldermen. The lord mayor is elected annually, on the 29th of September, from among the body of aldermen. The livery send a list of two candidates to the court of aldermen, and one of these, generally the senior, is chosen by them. He enters office, with much pomp, on the 9th of November, which is hence
