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