The lungs in the first case were evidently in the unexpanded fetal condition. Donaldson also gives (upon the authority of F. P. Mall) the combined volume of brain and spinal cord in the human embryo of 2 weeks at 0,04 cc, of 4 weeks at 0,2 cc, and of 12 weeks at 3,0 Fig. 3. From a photograph of the right view of the model. On this side, the lower part of the body wall is not seen as on the left side, but has been dissected

The lungs in the first case were evidently in the unexpanded fetal condition. Donaldson also gives (upon the authority of F. P.

On this side, the lower part of the body wall is not seen as on the left side, but has been dissected out to the mid-sagittal plane, giving a side view of the spinal cord, notochord, the descending aorta with its branches, and the pelvic viscera. Explanation (in addition to letters shown in Fig. 2): a' right aortic arch, al allantois. b Wolffian duct, ca caudal artery, cl cloaca. D duodenum, ha hypogastric artery, i intestine, n notochord. o gall bladder, r rectum, ra i-ight auricle, rv right ventricle, sp spinal cord, si' sinus venosus. m ureter. Its T-shaped upper ex- tremity, forming the anläge of the permanent kidney, is almost entirely hidden by the hypogastric artery, u]} urinogenital papilla, vv vitelline (omphalomesenteric) vein. These figures for the embryos of 2 and 4 weeks are evidently too large, however, being apparently larger than the volumes of the entire embryos of those ages. It will be observed from the preceding table that the heart is relatively large in the 11 mm embryo, being relatively about 6 times.
