doubt that such of our readers as have never seen the places they are intended to represent, will concur in the conviction that has been forced upon us by our inspection of them. The first of them that astounded us beyond measure was that called "Ancient Cross, Clonmacnoise." At this place we had erewhile spent some of our happiest hours, meditating among its tombs, and admiring alike its various ancient architectural remains, and the sublimely desolate but appropriate character of its natural scenery. So familiar had we grown with this most exciting scene, that we thought that we should have been able to identify every stone in it blindfold; but that was all a mistake: we had only a dim and erroneous vision of its features; we saw nothing accurately. For instance, the stone cross which forms the principal object in the foreground, and which gives name to this subject--this cross, which we had often drawn and measured, and found to be just fifteen feet in height, as Harris the antiquary had supposed before us, here appears to be more than twenty feet! while the base of it, which to our eyes always presented the appearance of a surface covered with a sculptural design of a deer-hunt, by men, dogs, chariots, and horses, is here an unadorned blank! The small round tower in the middle ground, which, as we believed, stood on the very shore, nearly level with the Shannon, has in this view mounted up the side of the hill. But what struck us as furnishing the most remarkable proofs of our defect of vision is, that the doorway of the great round tower, called O'Rourke's Tower, which, according to our measurement, was five feet six inches in height, and placed at the distance of eight feet from the ground, is here represented as at least twenty feet from it; and the stone wall of the cemetery, which, as it seemed to our perception, ran nearly from the doorway of the tower to within a few yards of the cross, has no existence whatever in the print, its place being occupied by some huge Druidical monument which we never were able to see. The perspective in this view is also of a novel kind, and well worthy of the attention of the Irish artists, and all those in Ireland who may hitherto have supposed that they knew something of this science. They will see that the level lines, or courses, on circular buildings, instead of ascending to the horizontal line when below it, descend to some horizontal line of their own; and that in fact there is not one horizontal line only in the picture, but perhaps a dozen, which fully proves that our previous notions on this point were wholly erroneous.
