TINY MOTOR FOR DENTISTS USE.

An electric motor, cv?u in sm-i!l sizes, is quite heavy for thd power u yields. For this reason dentists hr.vo been using a motor mounted on a bracket, and _ connected by a (IjjiMe •shaft with the point of application of tlie power. Recently, however, a miniature electric motor has been devised for the dentist's use which is &v small and weighs so little that it may l.e connected directly to the dental chucks and used as a hand tool, tlnu doing awaj r with the cumbersome universal shaft. In place of the shaft n light electric cord connects the motor with a lamp socket. The motor is one of the smallest ever made for commer c-ial use. Its weight is but 5J ounces, and it is 11 inches long by 1 j inches in diameter. It uses only 12 watte and operates at a speed of 15,000 revolutions a minute. It can be used either on direct or on alternating current. A control switch is mounted on the motor where it can be operated conveniently by tho hand. The speed of the motor may be controlled by a foot-operated rheostat. THE LAND OF THE LITTLE DUCHESS. AVe have heard so little of Luxembourg in the war that we are apt to forget that Belgium is not the only land the Germans criminally entered in order to break in, like midnight burglars, upon the unguarded frontiers of Fiance. Germany has announced that the invasion of Luxemburg was was no invasionst all; that the Government had practically consented to it, and been well paid for doing so. But the Grand has made her brave voice ring across the world, and has declared that she and her Government protested against the invasion to all the nations concerned. She indignantly denies that Luxemburg received, or would consent to receive, payment for the infamous wrong that Germany did her. The truth is that Luxemburg is a captive State, not a confederate. The last free net of the young Duchess wa* to draw her motor-car across the road to bar the path of the spoilers into lier capital. That was all her little country could do. The German Emperor had the audacity to visit the Duchess with offering* of roses, but she snubbed the Emperor and scorned iiis rose*. GIFTS FCm THE WOUNDED. The people who have done so much in the way of providing comforts for soldiers in hospital have, for the iao,jt parr, earned Tommy's grateful thanks There are, however, or.e or two dear old ladies who cannot understand tintin n military hospital there are somA articles which are about as useful as a white elephant would be. These kind but misguided people prohablv include the lady who sent 10.000 alarm clocks to Uganda "for the* use of sufferers from sleeping sickness." Out of a total import of food-stuff-, valued at £34,000,000, to the United Kingdom before the outbreak of hostilities, no less than £28.000,000 came from districts and along trade routes now practically unaffected by the war.
