    larger dimensions than any of those already noticed, which is set in motion by the steam-engine ; and to it the grinding stones, glaziers, and polishers, are attached by the wheel- bands. The wheel-bands consist of broad leather straps; and the connexion between the different wheels and the drum can be effected or discontinued in a moment, with the utmost facility, by putting the wheel-bands on or off. The different kinds of stones used in grinding, and the sizes employed, have already been described. In manufacturing a razor, both the dry and the wet stone are employed; and therefore a description of the different pro- cesses a razor undergoes will best explain the operations carried on in the hull of a grinding wheel. The razor is first forged out of a bar of steel. It is then sent to the grinder, who shapes it on the dry stone into the re- quired pattern, whilst it is in the soft state. After the razor has been shaped, it is returned to the forge, to be file-cut and marked: the mark stamped upon it is very frequently that of some distant firm; it may be in London, or Glasgow, or any other town. Why our manufacturers allow this, has often been a puzzle to me; for it most certainly has enabled others at a distance to gain a reputation they would never have obtained but for this procedure. The razor next undergoes the process of hardening and tempering, after which it is once more brought to the wheel, and ground to an edge on a wet stone. It is then laped on a tool the exact size of the stone on which it has been ground. The back and the end of the tang is glazed; and the whole of the blade is then wiped quite clean, and afterwards highly polished with crocus. It is next sent to the hafter, who places it in the scales (handle), aud sets (sharpens) the razor ready for use. Serviceable razors can be made at all prices, from one shilling to the elaborately finished and costly articles which were specially manufactured for the Emperor of the French. The following table will show the immense quantity of steel-
