BOOK NOTICES
ticularly for iritic adhesions is dis cussed by Wurdemann. The ear shows no particular articles of moment, except that in examination and in the descriptions of deafness. The Nose and Throat shows the usual discussion of the sinuses. The treat ment of hay fever has had some ad vance by antigens and tuberculin. Adenoids and tonsils again make their appearance with modifications of op erations and new instruments. The treatment of disorders of speech should be done in special hospitals ac cording to J. S. Greene. H. V. W. Bronchoscopy and Esophagoscopy, by Chevalier Jackson, M.D., Professor of Laryngology, Jefferson Medical College, Professor of Bronchoscopy and Esophagoscopy, Graduate School of Medicine, University of Pennsyl vania. Octavo of 346 pages with 114 illustrations and 4 color plates. Philadelphia and London: W. B. Saunders Company, 1922. This book is based on an abstract of the author's larger work "Peroral Endoscopy and Laryngeal Surgery which was published in 1914. It is
about one-fourth the size of the origi nal volume and is intended for a work ing manual, whereas the former vol ume is in text book style. A large number of corrections, revisions and additions have brought the subject up to date. This volume contains one new chap ter on "Acute Stenosis of the Larynx." Chapters to be found in the old vol ume are omitted in the new (1) sus pension Laryngoscopy, (2) External Laryngeal Surgery, (3) Intubation Dila tation of Chronic Laryngeal Stenosis, (4) Laryngostomy, (5) Malignant Dis ease of the Larynx, (6) Technic of Thyrotomy for Malignant Disease of Larynx, (7) Technic of Laryngectomy. As in all his publications, the author attempts to give by photographs, drawings, and word pictures, a clear conception of difficult mechanical problems. As is well known, most of Dr. Jackson's actual working pro cedures are original, and therefore the subject matter of his publications is to be found nowhere else in the litera ture. Needless to say this volume will be studied by all those interested in this special field. H. V. W.
ABSTRACTS Kidd, Leonard J. The fourth cranial nerve, British To. Ophth. v. vi, No. 2, 1922, p. 49. In this contribution the author shows: (1) That the decussation of the fourth nerve is not quite complete; in short, that it contains a few uncrossed fibers; (2) that the sixth nerve nucleus gives origin to uncrossed fibers exclu sively, all of which pass out in the homolateral sixth nerve; and (3) that the mesencephalic trigeminial root is not motor, and cannot therefore form the visceral motor component of the fourth cranial nerve. The author further discusses the embryologic, anatomic, pathologic and ex perimental evidence, as observed by himself and the views offered by other investigators, regarding the origin, crossing or uncrossed fibers and func-
tion of the nerve supply to the extrin sic muscles of the eye ball. He con cludes that the fourth cranial nerve has only two out of the four fundamental nerve components of a segmental nerve, viz.: (1) Somatic motor, and (2) Somatic afferent. A lesion strictly limited to the cells of one fourth nucleus will give almost complete paralysis of the contralateral superior oblique muscle, together with a very slight paresis of the homolateral superior oblique. Ignorance of the fact that the fourth nerve contains some direct fibers can lead to error in diag nosis. A pure sixth nuclear lesion gives homolateral signs alone, whereas a pure trochlear or oculomotor nuclear lesion of necessity gives bilateral pal sies or paresis. The vast majority of cases of ocular palsies are due to fas-
