DAVIS, In the Office of the Librarian of Congress, at Washington, D. C., U. S. A. Philadelphia, Pa., U. S. A.: The Medical Bulletin Printing House, 1231 Filbert Street. D1633 AUTHOR'S PREFACE TO FIRST EDITION. It was THE following lectures were delivered during the winter of 1883-4, before an audience composed of practicing physicians. It was the endeavor of the author to lay before his hearers (who were already familiar with the coarser anatomy of the brain) all that had been discovered in regard to its finer structure. important, too, to present this, so far as possible, as a harmonious whole. Much that was in controversy could barely be mentioned, while here and there only one view of a disputed question was given,—that view which appeared most likely to be correct, either from the author's own investigations or from the writings of trustworthy authors. This would be absurd if this work pretended to be anything more than an introduction into the study of the structure of the central nervous system. He, however, who wishes to inform himself still more accurately in this direction will find all that he desires in the magnificent volume of Wernicke, and particularly in the superb works of Meynert and Flechsig. Besides these, we possess in Schwalbe's Quain-Hoffmann's hand-book a very clear and comprehensive exposition of the anatomy of the brain. The student may also consult with great benefit the work of Henle, which is based mainly on his own views and investigations. After searching these authors, he will find still further sources of knowledge in the works of B. Stilling, Kölliker, Gudden, Clarke, and others. The author has in his own work (the results of which not at present be published in extenso) followed principally the method of investigation introduced by Flechsig, and has thereby come to entertain some views which differ from those commonly accepted. He has ventured, however, to introduce the results of his own investigations into this little monograph only so far |
