There is also in the Dining-room an interesting cabinet-sized portrait of Sir George’s younger brother, John Clerk Maxwell of Middleby, that genial, practical, individual Scotsman of whom a most interesting account is given in the life of his distinguished son, Professor James Clerk Maxwell. The picture is the work of his niece, Miss Isabella Clerk, and shows some traces of the amateur, especially in the size and uncouthness of the hands, but a comparison with the engraving from the portrait by Watson Gordon, given in the above-mentioned volume, proves it to be a substantially faithful likeness of the good old man. IX. We now come to glance at the portraits at Penicuik House which do not represent members of the Clerk family. Among the earliest of these, hung in the Dining-room, is a three-quarter-length seated portrait of Sir Archibald Primrose, Lord Carrington, that ancestor of the Rosebery family who played an important part in politics during the Restoration period, who fought under Montrose, was captured at Philiphaugh, and barely escaped being executed for treason; who was appointed Lord Clerk Register in 1660, and Lord Justice-General in 1676, presiding, in that office, at the trial in 1678, of Mitchell for the attempted assassination of Archbishop Sharp; and whose later years were spent in steady opposition to the administration of the Duke of Lauderdale. He is styled by Burnet “the subtelist of all Lord Middletoun’s friends, a man of long and great practice in affairs ...; a dextrous man of business, he had always expedients ready at every difficulty.” In the picture he appears in his black, gold-laced robes as Lord Clerk Register, his right hand resting on the arm of his chair, the left raised, and his face seen in three-quarters to the right, with its thin prominent nose drooping at the point, small chin, and lips rising towards the ends and pursed and dimpled a little at the corners. A similar picture, but only bust-sized, stated (Catalogue of Royal Scottish Academy Loan Exhibition, 1863) to be dated 1670, has been long at Dalmeny, and a copy of it was presented by Lord Rosebery to the Faculty of Advocates in 1883, and now hangs in the Parliament House. His Lordship has recently acquired, from the Rothes Collection, another, a three-quarter length, version of the picture; and we are informed that there is also a similar-sized version in the possession of Lord Elphinstone. A portrait of Sir Archibald Primrose appears in Mr. A. H. Millar’s list of the portraits at Kinnaird Castle, but we have not examined this work, and cannot say whether it is a repetition of the present portrait.
