Dentists say that the greatest difficulty they meet with in their work is the matching of false teeth witli the natural teeth of their customers. The tooth factories supply dentists with rings upon which are strung thin metal bars, each carrying a tooth at its extremity. There are twentyfive of these sample teeth, that run all the way from nearly white to a shade that is almost olive. Some of the twenty-five usually matches the patient's teeth, and, at any rate, enables the dentist to match the teeth by application at the factory. A Roman has offered King Humbert a novel instrument of warfare. This is a projectile which on being shot from a cannon and striking an object, will produce a luminouadisc of 100,000 candle power, and thereby expose to view an enemy's position by night at a distance of from three to four miles. Mr. David Bruce, said to be the inventor of the type-casting machine, recently died , at Brooklyn at the age of 90.
