ARCHEOLOGICAL DISCOVERY IN TH NORTH RIDING.-A very interesting discovery has during the past autumn, been made at Normanby, near Middlesbrough. In order to facilitate certain of the mining operations carried on at that place by the Messrs. Bell, it became necessary to form a new roadway at a lower level thar that hitherto in use, itself lower by four or five feet than the modern surface in the vicinity. During the process of the necessary excavations the attention of the engineer and workmen was drawn to the presence of human remains. There were many fragments of ancient pottery, portions of two broken querns, the upper stone of a third in an unfinished state, and eventually even a portion of a human jaw, with three teeth, The bones were principally those of the ox, and, judging from the form of a skull obtained in some degree of integrity, of bos longifrons. Some were of large dimensions, and those which had contained marrow Were, with few exceptions, broken across. There were besides numerous bones of the sheep and deer, and a few of the swine. Not a few of the shoulder blades of the sheep or deer were so small as to suggest the presence in Cleveland, at the time to which the deposit belonged, of very small varieties of the breeds represented. On none of these bones did there appear to be any signs of gnawing-perhaps a negative evidence of the absence of any species of dog at the time. There were also many small bones of various kinds, but too much decayed to admit of any attempt to decide to what creatures they had originally belonged. There was one, however, at least, which testified to the presence of articles of food derived from the sea (exclusive of others to be presently mentioned); aud that was a bone from the flapper, or breast fin, of probably either a seal or a porpoise. Some few of the larger bones showed signs of cutting, the cut parts presenting a rough, jagged edge, strongly suggesting that the cutting instrument employed had been very blunt or very rude. Besides these cut bones, one other, the metatarsal bone of a sheep or deer, was bored through transversely as well as longitudinally, the hole being perfectly circular All the bones, without any exception, were much coated, or their hollow parts lined, with earthy phosphate of iron, which after a few hours of exposure to the air assumed a very beautiful blue tint. Besides the bones just noticed there was a layer of shells-namely, those of the common sea mussel and the ordinary periwinkle-of six or eight inches in thickness, 14 or 15 feet in length, and of considerable but undetermined width. All the mussel shells had been opened, and in no instance did two still united at the hinge present themselves. This shell bed lay at a depth of 12 to 14 feet below the old road, and therefore 17 to 19 feet below the modern surface. The bones, pottery, and querns were most abundantly met with in the part of the deposit just above the shell-bed, and intermingled with them were twigs, leaves, sticks, chips, knots, or broken branches of trees, charcoal, a specimen or two of wrought wood (pegs or the like), hazel-nuts, acorns, ling, moss, bracken, sedges, rushes, a few seeds of plants, besides wingcases of beetles, half of a small, well-wrought and polished jet ring, and a rude bone peg or two. About five feet above the shell-bed lay an ochrey-yellow band of some inches in thickness, which, with all that lay below it (to a foot and a half or two or three feet beneath the shells), gave unquestionable evidence of having been deposited in water not liable to violent commotion. A careful inspection of the whole deposit and of the surrounding locality seems to lead to the supposition that there must have been a pool here in ancient times. There are reasons for assuming that the bed of this pool originated in the geological movement which created a fault in the adjacent bed of ironstone, which fault is shown clearly, in section, a few yards beyond the deposit. But as to the circumstances under which the deposit was made there is no evidence whatever on which so much as to found an hypothesis. There may have been a species of "lake dwelling," though no traces of its existence presented themselves. There may have been a settlement on the verge of the (probably) steep bank which encompassed one side of the pool, although on this supposition it is not very possible to accouut for the equable deposition of the shells and other light matters, and still less for the diffusion of the bones, pottery, &c., over a tolerably wide area. It is barely probable that a family lived in hats constructed in the overhanging trees. It is, perhaps, more probable that the site of the assumed dwelling or dwellings may have been demolished, and no attention drawn to it, at a period much earlier than that of the formation of the present road, that is to say, at the time when the earlier excavations and other works necessary towards quarrying the ironstone in the adjacent bank were in process of being carried out. As to the date of these curious remains, that is also too much a matter of conjecture; but, from the character of the pottery, the querns, and the jet ring, it is assumed to be not extremely remote. They are undoubtedly Celtic, and beyond that little that is positive can be alleged. The discovery of any kind of edged implement or weapon might, perhaps, have room for a more definite judgment, but nothing of the kind has been discovered. It may be added that the human jaw obtained was remarkably massive and large, and must have belonged to a person of huge proportions. The three teeth, which are still in their sockets, are of great size and very much worn down; indeed, nearly the whole crown is worn away-a fact which testifies plainly enough to the coarse nature of a very considerable portion of this ancient AD
