An efficient mouth gag and tongue depressor which I have been using for over six years is shown in the accompanying illustration (Fig. 1). It is modeled on the style of the old Hartman moutli gag, but involves an entirely new principle, in that it has a spatula so curved that it fits over the dorsum of the tongue, reaching the base of the epiglottis.

Figure 2 represents an apparatus devised by myself and Dr. F. A. Hamlin which adds very materially to the safety and ease of doing a tonsil operation. It consists of a
