transitions, but we think the advocates of the new theory should have begun by pointing them out if they exist. There is another difficulty in their way. How is their system to explain the position of the mummy-chamber in certain pyramids? Let us take that of Cheops as an example. If its internal arrangements had been fixed from the beginning, if the intention had been from the first to place the mummy-chamber where we now find it, at about one-third of the whole height, why should the builders have complicated their task by imposing upon themselves these ever difficult junctions? Would it not have been far better to build the pyramid at once to the required height, leaving in its thickness the necessary galleries? The same observation applies to the discharging chambers above the mummy-chamber. The whole of these arrangements, the high vestibule with its wonderful masonry, the chambers and the structural voids above them, appear to have been conceived and carried out at one time, and by the same brains and hands. Not a sign is to be found of those more or less well-veiled transitions which are never absent when the work of one time and one set of hands has to be united with that of another. Or are we to believe that they commenced by building a hill of stone composed of those different pyramids one within another, and that they afterwards carved the necessary chambers and corridors out of its mass? One of the heroes of Hoffmann, the fantastic Crespel, made use indeed of some such method in giving doors and windows to his newly-built house, but we may be sure that no architect, either in Egypt or elsewhere, ever thought of employing it. The disintegration to which it would lead may easily be imagined. We may here call attention to a circumstance which justifies all our reserves. There is but one pyramid which seems to have been built upon a system which, though much less complicated, resembled that which we are noticing in some degree, we mean the Stepped Pyramid of Sakkarah. Now we find that the whole of the complicated net-work of chambers and passages in that pyramid is cut out of the living rock beneath its base, and that they are approached from without by subterranean passages. The difficulty of deciding upon the position of the chambers in advance, and of constructing the galleries through the various slopes of the concentric masses which were to form the pyramid, was thus avoided, and the builder was able to devote all his attention to increasing the size of the monument, by multiplying those parallel wedges disposed around a central core of which it is composed.
