12 PREFACE 



terms are often misleading, and wherever this is the case, other names have been 

 substituted. 



An outline for a laboratory course in neuro-anatomy has been included, and 

 this has been so arranged as to be easily adapted by the instructor to his par- 

 ticular needs. 



Free use has been made of material gathered and arranged by others in the 

 various handbooks, texts, and atlases that deal with the nervous system. The 

 classification of the afferent paths and centers adopted here is based on the 

 work of Sherrington. The terms which he introduced and which are now coming 

 into general use have been employed. In the analysis of the cranial nerves the 

 American conception of nerve components, so ably presented by Herrick, has 

 been utilized. 



Illustrations have been borrowed from many sources, in each case duly 

 accredited, and our indebtedness for permission to use them is gladly acknowl- 

 edged. The majority of the figures have been made from drawings prepared for 

 this purpose by Miss M. E. Bakehouse. The large number of illustrations and 

 the excellent manner in which they have been reproduced is to be credited to the 

 generous policy of the publishers, W. B. Saunders Co. My thanks are due to 

 Dr. Olaf Larsell for reading the manuscript and for many valuable suggestions, 

 and to Mr. Michael Mason for assistance in reading the proof.
