The Duke is proprietor of the greater part of Argyllshire--a county having an area of 2,432,000 acres, of which only 308,000 are under cultivation. The greatest breadth of the mainland is about 115 miles; and from the windings of the numerous bays and creeks, with which the land is everywhere indented, the county is supposed to have more than 600 miles of sea coast. His chief seats are--Inverary Castle, on the banks of Lochfyne; Roseneath Castle, Dumbartonshire; Longniddry, Haddingtonshire; Halnaker, Sussex; and Argyle House, Camden Hill, London. THE RIGHT HON. H. A. BRUCE. The Right Hon. Henry Austin Bruce is a native of Wales. He was born at Duffryn, Aberdare, Glamorganshire, and is both by birth and training a thorough Cambrian. His father, who is still living, was for several years Stipendiary Magistrate at Merthyr, and once contested that borough unsuccessfully with Sir John Guest. He was originally a Mr. Knight--a patronymic which, in 1805, he changed to Bruce, and afterwards, in 1837, to Pryce. The Member for Renfrewshire is, therefore, described as the second son of John Bruce Pryce, Esq., of Duffryn, St. Nicholas, Glamorganshire, by Sarah, the second daughter of the Rev. Hugh Austin, Rector of St. Peter's, in Barbadoes. Paternally, he is a nephew of the late Lord-Justice Knight Bruce, who was spared to see him attain the dignity of Privy Councillor, but not long enough to witness his admission to the rank of a Cabinet Minister. It may be added, for the purpose of completing these domestic details, that his great-grandfather, Mr. Bruce of Kennet, was High Sheriff of Glamorgan more than 150 years ago; and, further, that he himself has been twice married, his first wife (to whom he was married in 1846, but who died in 1852) being Annabella, the only daughter of Richard Beadon, Esq., of Clifton, Gloucestershire; and his second wife, to whom he was married in 1854, being Norah, the youngest daughter of the late Lieutenant-General Sir William Napier, K.C.B., the author of that matchless military narrative, the "History of the Peninsular War," and distinguished also as the brother of the heroic conqueror of Scinde. The reader will thus perceive that the Member for Renfrewshire, who might be supposed from his patronymic to be a Scotchman, is not even connected closely by family ties with this part of the Island. His position, however, as the member for Renfrewshire, and his consequent intimate connection with the West of Scotland, may excuse his appearance in these pages.
