Excerpt from Embryology of Insects and Myriapods This text is the outgrowth of a course of lectures on the embryology of insects given by the senior author over a period of twenty years and now being continued by the junior author. It goes without saying that more is offered here than is presented in the time allotted to the subject in Cornell University. From year to year new topics were introduced and old ones laid by so that now from the accumulated subject matter the material for this book has been selected. It may well be, in the opinion of some readers, that certain phases of the subject, have been overemphasized and others have not been sufficiently stressed. To this can be said only that an effort has been made to present as balanced a treatment as the available material permits and that research students must of necessity refer to original sources for details that limitation of space prevents being included here. The authors have endeavored to preserve an impartial attitude on controversial questions - presenting in Part I the chief views on debat able points and in the chapters of Part II reflecting the Opinions of the several investigators on the subject of their research. Nowhere in the developmental history of the arthropods has the debate been more lively and at times more acrimonious than that relating to the origin of the mid-gut. The student is therefore warned after reading an account of the development of some species in the second part to turn to the first part for a discussion of points of questionable interpretation.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Observations on the Embryology of Insects and Arachnids During the three years of my acquaintance with Dr. Bruce, the rapid develop ment of his strong character was a constant pleasure to me, but while each day added strength to my belief that a most useful and distinguished career lay before him as a scientific investigator, I sorrow for the loss of an affectionate friend, rather than the death of a bright and promising pupil and student of nature. Our relation was not that of instructor and pupil, but an intimate personal friendship; to me he had brought his pleasures and successes, and his troubles and perplexities, and when I received, by the first mail which reached me at the Bahama Islands, the sad news of his death, I keenly felt the isolation which added intensity to the loss, and cut me off from a share in the expression of affection for his memory by his friends in Baltimore.
