Much is lost that would have been contributed had the author lived to complete her project. She knew these cases intimately and at first hand. Some of them she had followed for as long as twenty years, taking a personal interest in the individual children and their problems, advising them, assisting them, continuously observing them, and frequently testing and measuring them.
Particularly inadequate must be the accounts of the later development of the individuals herein described, for many of the details well known to the author she not committed to paper, since she fully expected to complete the manuscript herself. It is to be regretted that a follow-up study of these recent developments could not have been undertaken, and a hope is expressed that this may yet be done.
The chapters summarizing the group of twelve new cases are wholly without Leta S. Hollingworth's touch. It seemed desirable, however, to give such a summary as could be made under the circumstances. Had the original author been able to complete her book, we know that penetrating light would have been thrown on many of the more personal difficulties of these children of rare intelligence. This experience and insight can no longer be recovered. It must suffice to put on record chiefly the factual data now available, leaving it for future workers to follow up, if it should seem desirable, the subsequent career and destiny of the individuals whose early development and background are herein reported. Identification of these children is not made in this book, but the necessary facts for this purpose are on file and identification can be made at any time in the interests of educational research.
The third section of this book as originally outlined by Leta S. Hollingworth was to have dealt with general principles and with the social and educational implications of the study of children of very high intelligence. Up to the time of her death nothing of this character had been written by her explicitly, but throughout the years in which her projected book was developing she wrote a number of papers and reports bearing on the subject, and these were published from time to time in technical journals. It is well known that the content of these papers was dictated by her study of such cases as are herein reported, by her familiarity with the reports of other students in this field, and by her own very concrete and long experience in the organization and conduct of two experimental projects in the schools of New York City. It is, in fact, likely that the final chapters she had in mind for this book would have been a reorganization of the conclusions set forth in these articles.
Consequently, the last five chapters of this book, instead of being an attempt to guess at what the author might have said in them, are all from her own hand. They are either selections from or complete reproductions of papers she had published on what she considered to be the implications of her observations of children of rare intelligence.
The publication of this book has been made possible by funds granted by the Carnegie Corporation of New York. That Corporation is not, however, the author, owner, publisher, or proprietor of this publication, and it is not to be understood as approving by virtue of its grants any of the statements or views expressed herein.

[1] Chapter 9 of Gifted Children, published in 1926, bears the title "Children Who Test above 180 IQ (Stanford-Binet)." Some of the cases described more fully in the monograph manuscript are also sketched in that chapter.
