    methodological procedure of the statistical calculations. Among his colleagues who assisted me constantly in mastering technical difficulties and in finding proper solutions for ever recurrent problems, I particularly wish to mention Dr. Hans Luxenburger and Dr. Bruno Schulz. No effort was too great for them to make when they thought it would further the progress of this study. For assistance in editing the English text, I am immensely indebted to Mrs. Senta Jonas Rypins, who contributed all her experience to the textual work, and to Dr. Harold Rypins, who supplied authoritative and valuable criticism and advice whenever necessary. How difficult the task of Mrs. Rypins was, can only be juged by one who has watched its gradual completion and who has enjoyed the wholehearted and enthusiastic devotion of her collaboration. How well this task has been done, I must leave to the judgement of the reader. Here I can only reaffirm my pro found gratitude to her and to Dr. Rypins. I should like to express my thanks for facilitating the publication of this book to Dr. Nolan D. C. Lewis, who recommended the work to The National Committee for Mental Hygiene as a part of a Research in Dementia Precox and supported it in every other way possible, and to The Supreme Council 33 o , Northern Masonic Jurisdiction, U. S.A., which generously provided the financial aid. Grateful acknowledgment must also be made to* those who assisted me in the final editorial details of the manuscript, Dr. Carney Landis, Dr. M. M. Kessler, Mr. L. B. Fleishacker, Mrs. Amelia T. Daley, Miss Helen S. May, Miss Marie Olsen and Miss Dorothy Skene. In conclusion, I wish to point out that this monograph, as far as the statistical parts are concerned, tries primarily to meet the needs of psychiatrists interested in genetics. It may therefore be more detailed as to certain methodological questions and numerical results than may seem necessary to professional statisticians, familiar with the analysis of tables. However, it seemed advisable to interpret thoroughly a material so rich in tables and figures, in the hope that a complete understanding of the dry language of statistics might be the best way of directing scientific interest to the genetic problems of psychiatry.
