We know nothing of the safety or efficacy of the following recipe for toothache, which We find imputed to a practioner, in an eastern paper:—l: Gum copal, when dissolved in chloroform, forms an excellent compound for stuffing the holes ot decayed teeth. I have used it frequently, and the benefits my patients have derived from it have been truly astonishing. The application is simple and easy. I clean out the hole, and I moisten a little piece ot cotton with the solution; I introduce this into the decayed part, and in every in-itance the relief has been almost instantaneous; the chloroform removes the pain, and the gum copal resists the action of the saliva; and as the application is so agreeable, those who labor under this dreadful malady would do well to make a trial of it."
