Washington, D. C., Nov. 27, 1902.
To the Editor:
—To obtain a dropper which will drop and not flow in a small stream or fail to drop except by violent agitation, I have adopted the following plan:A piece of toothpick or a match stem is inserted between the cork and neck of the bottle, the rapidity of the flow being controlled by the tightness of the cork or the size of the splinter. The toothpick is then broken off close to the cork. It does not become occluded, and the number of drops each minute are about the same. It fills every requirement that the more expensive dropper does, and in some respects is far superior. Not infrequently we are compelled to intrust the anesthetic to an inexperienced person, and we have a little less concern if we know that the chloroform can be given drop by drop only,
