of reaction in bone-conduction from this and other hysterical symptoms. The diagnosis of hysterical deafness was made; the hearing was very much improved after treatment with the galvanic current and suggestion. ZIMMERMANN.

233. Two cases of progressive deafness where the examination with the Bezold's continuous-tone series suggested a very probable affection of the auditory-nerve trunk. Subcutaneous injections of strychnine in the neighborhood of the mastoid process were given, and a distinct improvement in hearing, with a diminution of the tinnitus resulted. The strychnine injections were given in 22 cases of tinnitus; in 17 cases a distinct diminution resulted. SACHER.

234. This monograph thoroughly reviews all that is known on this subject and endeavors to give a complete clinical picture of the tumors of the auditory nerve. Three personally examined. cases are added to the twenty-three found in literature. After a detailed description of each case, the results collected are as follows: Age of the patients varied between thirty and fifty-five years; two-thirds of the cases were male and one-third female. The etiology of the tumors was unknown. Severe traumatism was given as the cause in three cases, and the author is inclined to regard congenitally dispersed germ cells incited to pathological growth through traumatism as the reason for the growth of these tumors. The symptoms are described, with the growth of the tumor in the typical position in the recessus acustico-cerebellaris. General symptoms occur late in the disease and consist in vomiting and headache. Of the focal symptoms, in addition to the vertigo, the early appearing and generally the only symptom is the disturbance of hearing, which leads to complete deafness. The other symptoms consist of cerebellar ataxia, paresis of various ocular muscles, frequently the disturbance of the trochlearis and the disturbance of the fifth nerve with facial paralysis, and in the minor stages, disturbance in the region of the ninth to twelfth The characteristic picture of this disease is furnished by those cases in which complete nervous deafness is associated with various functional disturbances of a mild grade on the part of the organs in the posterior cerebellar fossa. In regard to treatment, the author believes that operative intervention is decidedly indicated on account of the nature of the disease, the typical localization, and the characteristic easy enucleation of the tumor mass.

BOOK NOTICES.

V.-Précis de Chirurgie cérébrale. Par A. BROCA, Chirurgien de l'hôpital Tenon; Professor agrégé à la Faculté de médecine de Paris; Membre de la Société de chirurgie. Paris: Masson & Comp., 120, Boul. St. Germain, 1903. Small 8vo of 488 pages, with 58 figures. Cloth binding, fr. 6.

This is an excellent treatise, both theoretical and practical. It is divided into two parts. The first contains general knowledge: the anatomy of the lobes, fissures, and convolutions of the brain, descriptive and topographical; the cranio-cerebral topography, the determining points and lines on the outside of the head with regard to the position of the parts in the head.

Then follows a chapter (III.) on cerebral localization, motor, sensitive, and sensory, and the centres of language.

Chapters IV., V., and VI. treat of the clinical indications and the operative management of brain surgery, and of the dangers of the intervention.

The special part begins with the traumatic lesions, to which are devoted ninety-eight pages. Then follow the intracranial complications of purulent middle-ear inflammation (162 pages), meningitis, sinus phlebitis, and abscess (epidural, cerebral, and cerebellar). These extensions of the purulent process of the tympanum and mastoid apophysis are described with great detail, supported by numerous operative and post-mortem verifications or corrections of the diagnosis; for instance, the apparent presence of meningitis, which was cured by extensive operations where neither abscess nor meningitis was found, which is explained by the dema surrounding more or less extensively the purulent foci in the middle ear and mastoid, cases of which have been noted by every aurist of sufficient practice.

Sinus phlebitis and abscess are described exhaustively in their pathology, symptoms, and surgical interventions. The exposi

tions are so clear, so well digested, and going over so much ground that the reader is fascinated by the variety and usefulness of the subjects.

The remainder of the Précis is devoted to intracranial tumors (very good statistics, symptomatology, and localization) and diverse brain lesions-hemorrhage and softening, meningitis and abscess from different causes, metastatic, etc., general paralysis, hydrocephalus, microcephalus, and various functional troublesepilepsy, psychoses, cephalalgy, and encephalocele. All these affections are carefully described. The author dwells on the differential diagnosis and the surgical and palliative treatment of these frequent and often occult diseases, pointing out which of them and in what way they are amenable to treatment.

The neat, interesting, and instructive book should, and surely will, be read extensively. H. KNAPP.

VI. - A Text-Book on the Diseases of the Ear. By Prof. ADAM POLITZER, M.D. Fourth edition, revised and enlarged, with 346 illustrations. Translated by MILTON J. BALLIN, Ph. B., M.D., and CLARENCE L. HELLER, M.D. Lea Bros. & Co., Philadelphia and New York, 1903.

This is the translation of the fourth edition of the classical text-book of otology by the famous professor of the Vienna University, which, by general consent, is considered as the standard treatise on the science and practice of aural surgery, a rank which it has maintained for so many years. The translation is by two young and talented aurists, one of New York, both Americans, who, as Politzer's assistants, made the translation in Vienna under the supervision of the author, while the German edition went through the press. The translation is well done, and the typography does credit to the well-known American publishers. We reviewed the appearance of the fourth German edition several months ago, and can only add that we are assured that the English rendition will meet with the favor which it has enjoyed before, and so fully deserves.
