6 PREFACE TO THE SECOND EDITION 1 



in this and numerous other laboratories has demonstrated that 

 a thoroughgoing application of these methods is of the utmost 

 value to the beginning student (cf. Johnston, '06 and '08). 

 In the senior author's Introduction to Neurology ('18) the 

 materials of neurology are organized from this standpoint as an 

 aid in the use of the larger text-books and atlases. 



The course in neurology here outlined can be covered by an 

 undergraduate class of properly prepared students in about 

 one-half of a school year, devoting one or two hours each week 

 to lecture and recitation and from six to eight hours to the 

 laboratory. Since, however, many colleges cannot devote 

 as much time as this to the nervous system, the Outline has 

 been so arranged that a selection can be made of those topics 

 for which time and materials are provided. Students of 

 zoology and vertebrate comparative anatomy will naturally 

 devote more time to the earlier parts of the Outline (sections 

 3 to 60) and may omit all of the work on the microscopic 

 structure of the mammalian nervous system. 



For several years past there has been offered at the Univer- 

 sity of Chicago a twelve-weeks course in neurology primarily 

 for students of psychology and education with meager bio- 

 logical preparation. These students make a rather thorough 

 dissection of the nervous system of the dogfish, thus making up 

 in some measure their deficiencies in knowledge of general 

 vertebrate anatomy. This is followed by dissection of the 

 brain of the sheep, with special reference to some of the more 

 important conduction pathways and functional centers, such 

 as the auditory, optic and olfactory tracts, pyramidal tract, 

 cortical localization, etc. Gross human material is freely 

 used for demonstration. Microscopic sections are studied, 

 illustrating the nervous elements, structure of the sense 

 organs, spinal cord, cerebral and cerebellar cortex, and if time 

 permits a few of the conduction pathways within the brain 

 stem. 



The course in neurology for medical students at the Univer- 

 sity of Chicago follows the general histology and a part, at 

 least, of the gross anatomy, and it is, in turn, followed by a 

 laboratory course on the physiology of the nervous system. 

 In this course, which occupies twelve weeks, the students
