position of the peripheral nerves; and the experience 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 ('15) the ma- 

 terials 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 labor- 

 atory. 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 University 

 of Chicago a twelve-weeks course in neurology primarily for 

 students of psychology and education with meager biological 

 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 audi- 

 tory, optic and olfactory tracts, pyramidal tract, cortical local- 

 ization, etc. Gross human material is freely used for demon- 

 stration. 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 University 

 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 do most of
