he regretted to perceive that hardly a vestige of their private houses or villas was anywhere to be found. In tracing the progress of Roman architecture, he had remarked that it had declined previous to the age of Dioclesian; but he was also convinced that the liberality and munificence of that emperor had revived, during his reign, a better taste, and had formed artists who were capable of imitating the more elegant styles of the preceding ages. He had seen this remarkably exemplified in the public baths at Rome, which were erected by Dioclesian. The interest which he felt in this particular branch of Roman remains, and his anxiety to behold a good specimen of the private buildings of this wonderful people, induced him to undertake a voyage to Spalatro in Dalmatia, to visit and examine the palace of Dioclesian, where, after his resignation of the empire, in 305, that emperor spent the last nine years of his life. He sailed from Venice in 1754, accompanied by two experienced draughtsmen, and M. Clerisseau, a French antiquary and artist. On their arrival at Spalatro, they found that the palace had not suffered less from dilapidations by the inhabitants, to procure materials for building, than from the injuries of time; and that, in many places, the very foundations of the ancient structures were covered with modern houses. When they began their labours, the vigilant jealousy of the government was alarmed, and they were soon interrupted ; for suspecting their object was to view and make plans of the fortifications, the governor issued a peremptory order, commanding them to desist. It was only through the influence and mediation of General Graeme, the commander-in-chief of the Venetian forces (probably a Scotsman), that they were at length permitted to resume their labours; and in five weeks they finished plans and views of the remaining fragments, from which they afterwards executed perfect designs of the whole building. Mr Adam soon after returned to England, and speedily rose to professional eminence. In 1762, he was appointed architect to their majesties, and in the year following he published, in one volume large folio, "Ruins of the Palace of the emperor Dioclesian at Spalatro, in Dalmatia." This splendid work contains seventy-one plates, besides letter-press descriptions. He had at this time been elected a member of the Royal and Antiquarian Societies, and in 1768 he was elected to represent Kinross-shire in Parliament ; which, was probably owing to the local influence of his family. A seat in the House of Commons being incompatible with employment under the crown, he now resigned his office as architect to their majesties ; but continued to prosecute his professional career with increasing reputation, being much employed by the English nobility and gentry in constructing new and embellishing ancient mansions. In the year 1773, in conjunction with his brother, James Adam, who also rose to considerable reputation as an architect, he commenced "The Works in Architecture of R. and J. Adam," which before 1776 had reached a fourth number, and was a work of equal splendour with the one above referred to. The four numbers contain, among other productions, Sion House, Caen Wood, Luton Park House, the Gateway of the Admiralty, and the General Register House at Edinburgh ; all of which have been admired for elegant design and correct taste ; though the present age, in its rage for a severe simplicity, might desire the absence of certain minute ornaments, with which the Adams were accustomed to fill up vacant spaces. Before this period, the two brothers had reared in London that splendid monument of their taste, the Adelphi ; which, however, was too extensive a speculation to be profitable. They were obliged, in 1774, to obtain an act of parliament to dispose of the houses by way of lottery. The
