The microscopic anatomy of tumors of the central and peripheral nervous system

"In 1933, Pio del Rio-Hortega presented this great monograph on the tumors of the central and peripheral nervous system before the International Cancer Congress in Madrid: The printed proceedings of that Congress appeared in 1934 ... a reproduction of the title page of that volume appears as the frontispiece of this volume ... Because this monograph is the initial complete treatment of these tumors by Rio-Hortega, it must be considered of major historical importance. Further, it is the foundation work for the interpretation and study of nervous system tumors by the silver methods. Because these methods are widely employed ... it was felt wise to make available, especially for non-Spanish speaking workers, a translation of this major contribution."--Translator's foreword.
