Excerpt from Regeneration of Crayfish AppendagesI am indebted to Professor Ayers for direction and advice during the first three years of the investigation, and to Professor Lefevre for many valuable suggestions afterwards. I also wish to express my appreciation of assistance given me by Professor E. G. Conklin, of the University of Pennsylvania, in making making certain revisions of the work, and by Dr. Charles Thom and Dr. C. M. Jackson in the preparation of material.Note: The publication of the present paper, practically completed in 1901, was at first postponed in order to incorporate in it the results of certain experiments which were at that time still in progress. Since the conclusion of these experiments, circumstances which have been unavoidable have unfortunately made it necessary to further delay the final appearance of the paper.
