LIST OF ILLUSTRATIONS. 



In respect to twenty-six figures we are indebted to the persons named in parenthesis, 

 either for the idea of a figure or for the use of an electrotype. Of the original figures, the 

 larger number were drawn by B. C. Cleaves, Professor of Free-hand Drawing in Cornell 

 University. The four plates of the brain were drawn and lithographed by Miss Q. D. 

 Clements, who also drew Fig. 81-82. Fig. 11-12, 14r-19, were drawn by Miss I. M. 

 Curtis; Fig. 126-128, by Mrs. S. S. Phelps Gage; and Fig. 92, 110-112, 121-123, by the 

 senior author. 



In preparing the drawings for the original figures, the specimens — now preserved in 

 the museum of Cornell University — were photographed with a vertical camera, as sug- 

 gested by the junior author (6"). The outlines of the drawings were traced directly from 

 these photographs ; hence the relative size and position of parts are accurately represented. 

 Finally the drawings were photo-engraved.
