An office for the administration of naval affairs, presided over by a lord high-admiral, whether the duty be discharged by one person, or by commissioners under the royal patent, who are styled lords, and during our former wars generally consisted of seven. The present constitution of the Board of Admiralty comprises the first lord, a minister and civilian as to office; four naval lords; one civil lord attending to accounts, &c.; one chief secretary; one second secretary. Two lords and one secretary form a legal Board of Admiralty wherever they may be assembled, under the authority of the board or its chief.
