By the employment of force from behind forward the base of the tongue is pulled away from the pharyngeal wall and fixed there. This allows free breathing space for the patient, and also puts the pillars of the fauces on the stretch so that their separation from the tonsil is much facilitated.
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
