The recent appointment of the above illustrious individual to the head of our naval administration is a gratulatory topic for every Englishman; and we doubt not the measure will contribute as largely to individual honour, as it will to the national welfare. In the abstract, nations resemble large families, of which kings are fathers or guardians; and the subdivision of this guardianship or paternal government, among the sons or younger brothers of the sovereign is calculated to promote unanimity among the governors, and to engraft with affectionate loyalty the hearts of the governed. Indeed, the tutelar presence of princes seldom fails to inspire courage, and to support the patriotic sons of arms even in the extremes of danger; and, although the princes of our times have seldom been distinguished in the camp of war,--we should recollect that Nihil sunt foris arma nisi est consilium domi. The DUKE of CLARENCE, who is next brother to his present Majesty, was born at St. James's Palace, August 21, 1765, at a quarter before four in the morning, and in the following month was baptized by the name of WILLIAM HENRY.

Previous to his leaving the Prince George, he was also present at the capture of a French man-of-war and three smaller vessels, forming part of a considerable convoy; but in neither of these instances was an opportunity offered for any distinguishing effort of bravery. On this occasion, the Spanish admiral, Don Juan de Langara, on visiting Admiral Digby, was introduced to his royal highness. During the conference between the two admirals the prince retired, and when it was intimated that Don Juan wished to return, his royal highness appeared in the uniform of a midshipman, and respectfully informed the admiral that the boat was ready. The Spaniard was surprised to see the son of his Britannic majesty acting in the capacity of an inferior officer, and emphatically observed to Admiral Digby, "Well does Great Britain merit the empire of the seas,
