present these principles rather than any detailed application 

 of them. In the selection of subject matter and mode of 

 treatment the author has been fortunate in having the advice 

 of many experienced teachers in several of these fields, who 

 have read the manuscript of this work or of selected chapters 

 and whose suggestions have contributed greatly to its value. 

 Especial acknowlegement of generous assistance of this sort 

 should be made to Doctors G. W. Bartlemcz, R. R. Bensley, 

 Harvey A. Carr, C. M. Child, G. E. Coghill, Mabel R. Fcrnald, 

 Joseph W. Hayes, Mary Stevens Hayes, F. L. Landacre, John 

 T. McManis, and R. E. Sheldon. 



The materials presented in this book are arranged in three 

 groups: (1) Chapters I to VII discuss the more general neurologi- 

 cal topics; (2) Chapters VIII to XVIII comprise a brief account of 

 the form of the nervous system and the functional significance of 

 its chief subdivisions in general, followed by a review of the archi- 

 tectural relations of the more important functional systems; (3) 

 Chapters XIX to XXI are devoted to the cerebral cortex and its 

 functions. Readers whose chief interest lies in the general neu- 

 rological questions may omit much of the detail comprised 

 within the second group of chapters or use these for reference 

 only. To facilitate ready reference the general index has been 

 prepared with especial care, and with it is combined a brief 

 glossary of some more commonly used technical terms. In the 

 text some of the more special topics, which may be omitted if 

 a briefer presentation is desired, are printed in smaller type.
