The Dental cosmos . he files ofsome dental journals there were discovered illustrations, some ofwhich are appended, printed from electrotypes taken from the originalwood-cuts without the slightest change or alteration in any of them.

The necessary space ob-tained, I take a piece of fine hard-drawnwire, about the size of a common pin,and winding one end of it twice aroundthe middle of the oblique tooth, veryclosely, I pass the other end along to thebicuspids or molars, to which I attachit by means of a joint-mechanism of twonicely adjusted bands or rings,—form-ing a kind of yoke, which is slippedover two of the bicuspids or molars, and is prevented from slippingup to the gums by means of wire clamps which hook on to theirgrinding-surfaces. (Such spring-lever rotators are now made of pianowire (Fig. 1, A). These bands or rings, or skeleton caps on. TEETH-REGULATING APPLIANCES, ETC. 115 single teeth, or a kind of yoke (Fig. 1, B), when coupling twoadjoining teeth, were often made by the mechanical dentists of twenty-five years ago, but many of those who are yet among us were notwriters for the press, and illustrations were then rare, and so it comesto pass that many well-known devices are not a matter of indisputablerecord, as it is an object of the present writing that some of them shallhenceforth be.) These clamps may be so constructed, when anoperation requires it, as to prevent the teeth of the upper and lowerjaw from coming in contact with or overlapping each other. (Fig. 2shows such 1 wire clamps on a molar ring, or collar, C. See It will be seen at once that if this apparatus is rightly applied,the hard-drawn wire being elastic, and serving at once as lever andspring, will bring the oblique tooth round to its place in a short time.
