Journal of Anatomy and Physiology, Vol. 49 (Classic Reprint)

Book excerpt: Excerpt from Journal of Anatomy and Physiology, Vol. 49 The embryo which is the subject of the following investigation was obtained in January 1913 in the Frauenklinik at Giessen (director, Professor Opitz) by Operation on a woman in whose case an excision of the uterus was rendered necessary on account of tuberculosis, and came into the hands of Professor Keibel through the kindness of Dr J aschke. It is now included in the Reibel series as No. 1495 at the Anatomical Institute of the Uni versity of F reiburg in Breisgau. The embryo came into the fixing fluid in an exceedingly fresh condition, and, when a series had been made, proved to be in such an excellent state of preservation that I undertook, at Professor Keibel's suggestion, a description of the whole anatomy, with the intention of making it as complete as possible as far as the more interesting points were concerned. Accounts of the morphology of individual embryos have been frequent in the literature Since the time of His; and although a certain amount of overlapping must obviously occur in the observations of various authors, the value of such work is none the less very appreciable. An accurate idea of a given stage in the development of an organ or part cannot be scientifically founded on a single description; and just as our knowledge of adult morphology has been built up by the combination of often very divergent interpretations of a given condition, in the same way must our data, with regard to the course of embryological evolution, be raised to a higher plane of scientific accuracy by the elimination of the personal factor in the equation.
