Figure 7E shows a section through the plane 770 of figure 7. It is in the region of the umbilicus, _u_, and the extreme caudal end of the stomach which has been called the gizzard, _gz_. The small size of the gizzard is due to its being cut near its caudal margin. The enteron is here cut in no less than seven places: the reason for this will be evident on examination of the plane of the section as shown in figure 7. Dorsal to the gizzard the section cuts the so-called caecum, _ce_, a little nearer its anterior end than is shown in figure 7. The duodenum, _d_, is cut at five points, and has about the same structure as in the preceding figure. The character of the duodenal loops that causes the rather curious appearance of the present figure will be readily understood by reference to figure 7, though the reconstruction is not mathematically accurate. The ventral projection of the lower loops of the duodenum into the umbilicus is seen both in the present figure and in the reconstruction. The loop of the duodenum that, in the sections, is seen to lie directly ventrad to the gizzard, in the reconstruction is shown too much to the side of the latter organ. The descending loops of the duodenum are cut in such a way that the surrounding mesoblast forms a continuous mass of tissue. Figure 7F represents a section through the plane 901 of figure 7. The section passes through the kidneys, _k_, the edge of one posterior appendage, _pa_, the large intestine, _il_, and two regions of the small intestine, _i_. The large intestine is here a thick walled, cylindrical structure, _il_, hanging from a thin mesentery, _ms_, in the much reduced body cavity. The layers of its wall are much more fully differentiated than in the more anterior regions of the enteron. The epithelium is here stratified instead of simple columnar, and the folds into which it is thrown are broader and less numerous than in the duodenum above described. Ventrad to the large intestine, and almost in contact with it, is seen the allantois, _al_, whose general outline was noted in connection with figure 7. It is an irregular structure, consisting of a very thin outer layer of mesoderm, lined with a single layer of flattened epithelial cells. Lying at a considerable distance ventrad to the main body of the section, are seen the two sections of the small intestine, _i_, surrounded by irregular strands of tissue from the umbilicus. The structure of these two intestinal loops is about the same as in the more anterior region described above. Figure 7G, the last of this series, represents a section through the cloaca, caudad to the urinary openings, in the plane 1060 of figure 7. The epithelium of the cloaca is, of course, simply a continuation of that of the surface of the body, somewhat thickened, perhaps, in the deeper regions.
