 Psychology. 



The Author acknowledges his indebtedness to the 

 Chicago Laboratory Supply Co. and to Richards & Co. for 

 the cuts used in Appendix C. He takes this opportunity 

 to express his thanks to Dr. W. K. Jaques for preparing 

 the chapter on Physiological Haematology, and to Mrs. 

 Jaques for illustrating the same; to Dr. H. M. Richter for 

 the chapter on Pharmacology; to Dr. A. M. Hall for the 

 lessons on Normal Ophthalmoscopy and Skiascopy; and to 

 Miss N. S. Hall for the illustrations of the first six chapters.
