About six or seven years ago, when the scene was set for a tonsillectomy under local anesthesia, I experienced one of those unpleasant thrills which sooner or later come to every one who performs operations of any kind. The patient was sitting in the operating chair, the tonsillar pillars had been painted with iodine, and 6 cc. of 0.5 per cent procaine hydrochloride with 5 drops of epinephrine (1: 1,000) to the ounce (28.35 Gm.) had been injected, when he complained of a generalized tingling of the hands and feet, promptly followed by a stiffening of the arms in an adducted position with the typical "obstetric" or "penholding" hand of tetany, the fingers being straightened and the thumbs adducted. Both hands were also adducted. I had visions of the patient going into generalized convulsions and dying before anything could be done, as I had seen one do in a clinic
