range of pinnacles is again inferior to the northern and western, and visibly of later date. Then the screen, which most writers have described as part of the original fabric, bears its date inscribed on its architrave, 1394, and with it are associated a multitude of small screens, balustrades, decorations of the interior building, and probably the rose window of the south transept. Then come the interpolated traceries of the front and sides; then the crocketings of the upper arches, extravagances of the incipient Renaissance: and, finally, the figures which carry the waterspouts on the north side--utterly barbarous seventeenth or eighteenth century work--connect the whole with the plastered restorations of the year 1844 and 1845. Most of the palaces in Venice have sustained interpolations hardly less numerous; and those of the Ducal Palace are so intricate, that a year's labor would probably be insufficient altogether to disentangle and define them. I therefore gave up all thoughts of obtaining a perfectly clear chronological view of the early architecture; but the dates necessary to the main purposes of the book the reader will find well established; and of the evidence brought forward for those of less importance, he is himself to judge. Doubtful estimates are never made grounds of argument; and the accuracy of the account of the buildings themselves, for which alone I pledge myself, is of course entirely independent of them. In like manner, as the statements briefly made in the chapters on construction involve questions so difficult and so general, that I cannot hope that every expression referring to them will be found free from error: and as the conclusions to which I have endeavored to lead the reader are thrown into a form the validity of which depends on that of each successive step, it might be argued, if fallacy or weakness could be detected in one of them, that all the subsequent reasonings were valueless. The reader may be assured, however, that it is not so; the method of proof used in the following essay being only one out of many which were in my choice, adopted because it seemed to me the shortest and simplest, not as being the strongest. In many cases, the conclusions are those which men of quick feeling would arrive at instinctively; and I then sought to discover the reasons of what so strongly recommended itself as truth. Though these reasons could every one of them, from the beginning to the end of the book, be proved insufficient, the truth of its conclusions would remain the same. I should only regret that I had dishonored them by an ill-grounded defence; and endeavor to repair my error by a better one.
