operations are open to the criticism of unnecessary danger from injury to the cerebellum or to the facial nerve. The results of all the operations show that there was probably no direct connection between the irritation of the peripheral end of the auditory nerve and the tinnitus, because whatever improvement was noted came very gradually. CONCLUSIONS. The foregoing records justify the following conclusions : 1. Carefully selected cases of tinnitus, with the nerve stimulus located in the

A technic which offers little inconvenience from hemorrhage, no danger from bony spicules, and a minimum of evil from compression of the cerebrum, or espe-cially of the cerebellum, gives a good prognosis of recovery from the operation and in selected cases a cessation of the tinnitus. 3. If, after appropriate general and local treatment, grave tinnitus still exists, we are called on to recommend the section of the auditory nerve, provided the source of the tinnitus is believed to lie in the peripheral portion of the auditory nerve. . 4. Section of the acoustic nerve will be as effective for the cure of aural vertigo as for peripheral tinnitus. DISCUSSION. Dr. John F. Barnhill, Indianapolis, asked if all the patients in whom parts of the auditory nerve were cut died from pneumonia, and if there was an explanation for two-thirds of the patients dying from this cause. Dr. Bryant said in reply to the first question that one patient died of pneumonia after the operation, one died apparently of hemorrhage of the medulla, and the third was alive one year after the operation. In reply to the second question he said that he thinks it due to injury to the cerebellum, which seemed to be the primary cause.
