my friend Dr. Smith Ely Jelliffe, of New York, who kindly invited me to take part in the "Extension Course" at Fordham University. These lectures were given in September, 1912, in New York.
I must here also express my best thanks to Dr. Gregory, of Bellevue Hospital, for his ready support of my clinical demonstrations.
For the troublesome work of translation I am greatly indebted to my assistant, Miss M. Moltzer, and to Mrs. Edith Eder and Dr. Eder of London.
Only after the preparation of these lectures did Adler's book, "Ueber den nervösen Character," become known to me, in the summer of 1912. I recognize that he and I have reached similar conclusions on various points, but here is not the place to go into a more intimate discussion of the matter; that must take place elsewhere.
