A Student?s Text-Book of Zoology, Vol. 3 of 3: Tunicata, Enteropneusta, Echinodermata, and Arthropoda (Classic Reprint)

Excerpt from A Student s Text-Book of Zoology IN parting with the present volume I have the satisfaction of feeling that I have accomplished the first part of the task which I set myself fourteen years ago. When I began I looked forward to executing the whole work, both Special and General Parts, myself in seven or eight years. That expectation has not been realized. Indeed had it not been for the assistance given me by my colleagues, Mr. J. J. Lister and Mr. A. E. Shipley, the present volume would have been far from completion. Thanks to their generous -co-operation it is now finished, and I am in a position to turn my attention to the General Part. It is satisfactory to have finished it, but it is impossible to avoid a feeling of regret that owing to circumstances which were unforeseen when the work was commenced it has occupied so many years and that the General Part, to write which the Special Part was undertaken, is not yet begun.
