Excerpt from Orthogenetic Evolution in Pigeons, Vol. 1: Posthumous Works At the mature age of 50 years Professor Charles Otis Whitman began the work now presented in these volumes, and the long task was still incomplete when, 18 years later, on December 6, 1910, a brief illness terminated the work and life of this investigator, to whom biology and many American biologists especially are so much indebted. After six years, the efforts of some of his friends to make the results of his long labors available to others are nearly concluded. This task has been necessarily shared by a number of persons and organizations, and the demands upon some of them have been so considerable and unusual that the nature of their endeavors is here most gratefully acknowledged. The continued maintenance of the large collection of pigeons upon which this series of studies was based was essential to a presentation of anything more than a fragment of the results; it was necessary to learn the term of life and the sex of all the surviving individuals; and further breeding or testing of certain mutants among them was scarcely less urgent. This formed one of a number of heavy exactions upon those who have felt the necessity of presenting the largest possible portion of the author's results. The whole of these and other obligations, during the first year, was shared by Mrs. C. O. Whitman and by the editor, who was generously assisted by unasked grants from the A. A. Sprague Institute of Chicago and from the Laboratory of Experimental Therapeutics of the University of Chicago. During the five following years the Carnegie Institution of Washington has fully maintained the work - during two years at Chicago and for the succeeding three years at the Station for Experimental Evolution at Cold Spring Harbor, New York; that Institution has also assumed the entire expenditures incident to the publication of these volumes. For all this generous assistance the editor expresses enduring obligations. Not more than one-fifth of the matter herewith presented was found to approach a stage of readiness for publication; it has required some years to bring the results to their present form. Even now we have been unable to utilize all of the records and data, and many of the carefully prepared illustrations are also omitted. If our progress in the preparation of these materials has seemed lingering and slow, it should be said that much time has been given to all those materials which proved impracticable for use as well as to those which are now incorporated in the work. It was, however, in some cases found obligatory to become familiar with a subject as to which only records and raw data were avail able. Again, other and nameless difficulties have sometimes attended our efforts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
