the river front. The great increase of extent required some device for breaking the monotony and comparative lowness of this long front. He was strongly averse at all times to setting back the wings, or greatly advancing the centre of an architectural front, so as to break its line, when seen in perspective, and interfere with its apparent size. He was reduced therefore to attempt variation in outline, by slightly raising the whole centre, by heightening into towers the masses which flanked it, and by introducing visible roofs and turrets. This last change was one of principle; the “castellated” form necessarily disappeared at once, the parapet became subordinate, the turrets, originally battlemented, now terminated in tops, which, after many trials, and with some reluctance, were made of the ogee form. An upward tendency was given to the whole. The towers of the front remained for some time without visible roofs, and when the roofs were introduced they were so kept down (in deference to the advice of others) in relation to the angle turrets, that some confusion of principle resulted. He regretted afterwards that he had not kept down the pinnacles, and made the roofs boldly predominant. At the same time a change was made as to the buttresses of the whole front. They had no thrust to sustain, they interrupted the cornice and string-courses, and interfered with the panelling. For these reasons Mr. Barry himself disliked them, and, external criticism coinciding with his own feeling, he resolved to change them into turrets, which were free from all these objections, and which would tend at once to elevate and break the sky-line, and by their greater projection to relieve the flatness of the front. These turrets, once introduced, must of course prevail throughout; they made their appearance accordingly in the prominent masses of the wings, and so the change of the whole character of the front was complete. This alteration may be considered to have been more or less occasioned by the extension of front; other changes were made without any such ground. In the original design the windows of the two principal stories were set in arched recesses, with no string-courses to mark the divisions of the stories, united, as it were, under one head. This was now altered; the internal arrangements were manifested by the complete separation of the two stories; the recesses and the pointed heads of the windows of both stories were abolished, and in the attic story of the centre the continuous arcading was changed into sets of triple openings, so as to harmonize with the three-light windows below. These changes were less generally approved, as tending to give a flatness to the front, which the changes noticed in the preceding paragraph were not sufficient to remove.
