II. GENERAL LABORATORY DIRECTIONS 



1. The laboratory course here outlined includes the dissec- 

 tion of the nervous systems of several vertebrate types, includ- 

 ing man, and the microscopic study of selected portions of 

 the human brain and sense organs. If microscopic prepara- 

 tions of the human nervous system are not available, those 

 from other mammals will answer very well for most purposes. 

 Each student should provide himself with scalpels, scissors, 

 forceps, drawing paper and pencils and one or two orange-wood 

 or bone manicure sticks for blunt dissection and teasing of brain 

 tissue. Compound microscopes must be provided. A simple 

 magnifying lens is also necessary for low-power examination of 

 microscopic sections. (For the requirements of this course the 

 eyepiece of the compound microscope makes a satisfactory 

 substitute for a dissecting lens. Hold the slide to the light and 

 examine it through the inverted ocular.) 



2. The point of view from which this Outline has been pre- 

 pared is the same as that of the senior author's Introduction to 

 Neurology (Philadelphia, 1915), and it is assumed that this 

 book is available for study throughout the course, frequent 

 references being made to it in lieu of full descriptions in the 

 Outline. The first seven chapters of this work should be read 

 early in the course to give the necessary background for the 

 laboratory work. The illustrations in Burkholder's Anatomy 

 of the Brain (second edition, Chicago, 1912) will be found very 

 helpful in the study of the brain of the sheep. Other reference 

 books will be cited throughout the text. The titles of these 

 works are assembled in the Bibliography at the end and the 

 works are referred to in the text simply by the author's name 

 followed by the date of publication. Constant use must be 

 made of standard text-books and atlases of the gross and 

 microscopic anatomy of the human nervous system. The 

 following list includes some of the works of special value for 

 this purpose:
