The UNITED KINGDOM of GREAT BRITAIN and IRELAND, as it is officially denominated, contains an area of 117,921 square miles, with a population at the last census of 26,861,000 (1841), which is now increased to about 28,500,000. The Colonies and Possessions of the Crown contained in 1842 5,224,447 inhabitants. The possessions of the East India Company have a population of somewhat more than 100,000,000; and the countries over which that Company has assumed the right of protection, which is rapidly changing to sovereignty, about 35,000,000 more. The political authority of the Kingdom is vested in the three Estates, sovereign, lords, and commons. The House of Peers consists at present of 457 members of whom 30 are clerical; 28 Irish and 16 Scotch representative peers, elected, the former for life, the latter annually; the remainder being hereditary peers. The privileges of the peerage consist in membership of the Upper House of Parliament; freedom from arrest for debt, and from outlawry or personal attachment in civil actions; the right of trial, in criminal cases by their own body, whose verdict is rendered, not upon oath, but upon their honor; in the law of _scandalum magnatum_, by which any person convicted of circulating a scandalous report against a peer, though it be shown to be true, is punishable by an arbitrary fine, and by imprisonment till it be paid; and in the right of sitting covered in any court of justice, except in the presence of the sovereign. The House of Commons, which, by gradual encroachments upon the other Estates, and especially by the prerogative which it has acquired of originating all money-bills, has become the paramount power of the state, consists of 656 members, of whom 469 are for England, 29 for Wales, 53 for Scotland, and 105 for Ireland. The revenues for the current year, according to the estimate of the Chancellor of the Exchequer, amount to £52,285,000, and the expenditures to £50,763,582, leaving a surplus of £1,521,418. The national debt of Great Britain and Ireland, funded and unfunded, amounted, Jan. 5, 1850, to £798,037,277, involving an annual expenditure of more than £28,000,000, absorbing considerably more than one half of the public revenues. The military force of the Kingdom is as follows: Household Troops 6,568 Soldiers of the Line, in pay of the Crown 91,956 " " " East India Company 31,100 Colonial Corps 6,272 Making in all 129,625. The whole number of troops stationed in the United Kingdom is about 61,000, of whom 24,000 are in Ireland. The force of the British navy in Dec. 1848 is thus given in the Royal Calendar for 1849:
