Excerpt from The American Journal of Anatomy, 1915, Vol. 17 I have received valuable help from my father in this work, for which I am very thankful. I have prepared the following summary so that what we know of the comparative distribution of mitochondria in vertebrate nerve cells may be seen at a glance. The evidence which these investigators have presented will now be considered. Guinea-pig Nageotte ('09 a, p. 472) demonstrated certain bacilli-like bodies in peripheral nerve fibers fixed in Tellyesniczky's bichromate acetic fluid and stained with Altmann's anilin fuchsin. He found them also after preliminary fixation in 10 per cent formalin followed by Tellyesniczky's fluid and staining in the same way.

Excerpt from The American Journal of Anatomy, 1912, Vol. 12 Born's article reviews the earlier development of the cloa eal region in a very complete manner, and the substance is as follows: The entoderm of the enteron comes into direct relation with the surface ectoderm in the pharyngeal and cloacal membranes during the formation of the head and tail folds. Both of these membranes lose their primitive position and become folded into the substance of the embryo through increase in the surrounding mesoderm. The allantois, which is developed dorsally in the mammalian embryo (human and guinea pig excepted), shifts to a ventral position on the gut, and is gradually displaced from its intimate relation to the yolk sac through increase in the amount of mesodermal tissue. The primitive streak is carried to the ven tral surface of the body during the formation of the tail fold, and forms the whole or part of the cloacal membrane. Kolliker Strahl and Bonnet believe that the caudal end of the primitive streak is made up of applied layers of ecto and entoderm, and that it enters as such into the formation of the cloacal membrane. Keibel argues that this primitive rela tion of the ecto and entoderm is lost through interposition of mesoderm; the latter disappearing later with restoration of the original two layered condition.

Excerpt from The American Journal of Anatomy, 1917, Vol. 21 The difference in size in the two figures is, I believe, without special signifi cance.

Excerpt from The American Journal of Anatomy, Vol. 15: 1913 1914 The present paper includes statistical data upon certain phases of the growth Of the body as a whole and more especially the relative growth and variability Of the individual organs in the albino rat. A study Of this kind may be Of value in two respects. In the first place, it should give a better insight into the nature Of growth, a fundamental biological phenomenon worthy Of more study for its own sake. In the second place, a more complete knowledge Of the process Of growth, including the limits Of nor mal variation, should be Of value for reference in experimental work Of various kinds, for which the rat is Often used.

Excerpt from The American Journal of Physiology, 1915, Vol. 37 The general form of this curve is familiar. The majority of the variates lie close in magnitude to the mean, and therefore the greater part of the area enclosed between the curve and the axis of the abscissae lies close to the maximum ordinate, i.e., that expressing the number of variates exactly equal in magnitude to the mean. The curve slopes away upon either side of the mean, at first rapidly and then more slowly. The abscissa of the point of inflexion is the standard deviation.

Excerpt from The American Journal of Anatomy, Vol. 29: May, 1921 November, 1921 With the present volume The American Journal of Anatomy enters a new phase of its history. A transfer of actual ownership occurred some months ago, but only now have the results of this change actually expressed themselves. The first most noticeable effect is a partial transformation in the personnel of the Board of Editors of The Journal, and a word of explanation and statement of intentions seem proper. The Journal was originally founded by a small group of Anatomists who up to the past year retained ownership and the responsibility for its editorial management. These trustees, along with other members of their Editorial Board, a number of years ago delegated the business arrangements and the publication of The Journal to a central office established by The Wistar Institute of Anatomy. The advantages of this arrangement, both in facilities for publication and distribution of The Journal, have been manifold. The trustees realizing these advantages finally deemed it proper to actually transfer their ownership of The Journal to the Wistar Institute of Anatomy, with the understanding that the editorial management and scientific policy would be arranged for between The Wistar Institute and the American Association of Anatomists. An agreement has been reached between The Wistar Institute and the Association of Anatomists whereby a Journal Committee of the Anatomists has been established, and a proper cooperation of the Institute and the Association in the future affairs of The American Journal of Anatomy is assured. In the scientific policy and purposes of The Journal no change has occurred. The aims and ambitions of the present editors are none other than those of their predecessors.
