BOOK NOTICES
Louisa Lee Schuyler, an exceptional woman with vision far beyond the ordinary, who made such important contributions to the prevention of blindness that shortly before her death she was selected by the National Society for the Prevention of Blindness, of which she was one of the founders, to be the recipient of the Dana Medal for outstanding contributions in this field. It is fitting that more than passing notice of this anniversary of her birth should be taken. Miss Schuyler had been actively interested in matters of social welfare for many years when in 1908 she read an extensive report by Dr. Park Lewis on the condition of the blind in New York State. Twenty pages of this report had to do with the prevention of blindness, and of particular significance to her was the statement that a large part of the existent blindness could be avoided. She focused her attention on one feature, that of the unnecessary blindness caused by ophthalmia neonatorum. She appealed to Dr. Lewis to point out to her what she could do to help, and within six weeks she had organized the New York State Committee for the Prevention of Blindness and had succeeded in getting a subsidy of $5,000 from the Russell Sage Foundation. The first efforts of the organization were directed towards disseminating the knowledge of the prophylactic action of silver nitrate in preventing gonorrheal ophthalmia when instilled into the eyes of babies at birth. Very quickly other possibilities for blindness prevention were recognized, and the committee entered upon other tasks. In 1915 the name of this committee was changed to The National Committee for the Prevention of Blindness, and its scope was enlarged to fit the name. In 1928 the National Committee became the National Society, and one year later was instrumental in organizing the International Association for the Prevention of Blindness.
Other achievements of this remarkable woman were the founding of the New York State Charities Aid Association; establishing the system of state care for the insane in New York; and aiding the establishment of the first training school for nurses at Bellevue Hospital. In 1915 she was awarded the degree of Doctor of Laws at Columbia University. She was a remarkable figure, and a tribute should be paid to her on her hundredth anniversary. Lawrence T. Post.
BOOK NOTICES STUDIES OF THE VIII NERVE. By the Research Study Club of Los Angeles. Clothbound, 268 pages, illustrated. St. Louis, Laryngoscope Press, 1937. The fifteen papers composing this symposium, were written by fourteen authors; some by two in collaboration. They have for the most part been published in the Laryngoscope; although one comes from the Transactions of the American Ophthalmological Society. Two of the papers, on "Lesions of the cerebellum," 48 pages, and on "Flying blind," 15 pages, with the Foreword, on the history of the Research Study Club, have not previously been published. The volume is in good type, well printed, and neatly and substantially bound. It will all be of interest to those who practice both ophthalmology and otolaryngology, and has some features that will interest those who practice only ophthalmology. The eighth nerve has been so designated only in the last century. Before that it was called the nervus acousticus; or, as Winslow called it, the portio mol/is of the seventh cranial nerve, the facial nerve being the portio dura. In general, throughout medical literature, it has been called the auditory nerve; and the ear has been recognized as only an organ of
