Excerpt from A Contribution to Insect Embryology, Vol. 1: An Inaugural Dissertation My German co-workers in the field of insect development will probably regard my treatment of the literature as rather perfunctory; but Prof. Graber, Dr. Heider and others have given from time to time such complete resumes of past and current literature that I feel justified in departing from the general custom. If I have failed to give credit where it is due, I beg that this may be regarded as a fault of omission and not as a fault of commission. I would express my sincere gratitude to Prof. C. O. Whit man for his kindly guidance and friendly counsel throughout the progress of my work in his laboratory at Clark University during the autumn and winter, and at the Marine Biological Laboratory during the summer months, of 1891 and 1892. I am also indebted to Mr. S. H. Scudder for the identification of several Orthoptera. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
