The first is the fonnation of the coelom. The mesoderm of the chick is originally a continuous sheet of cells as is shown in Lilly's figm-e 40, A and B, on page 70' and in Duval's figures 18-i to 188 on i)late 12. As the cliick grows larger this double sheet of cells forms a plexus with wide interspaces in the network where the mesoderm is entirelj' lacking lea\'ing nothing but ectoderm and endodenn. The coelom now begins as clefts full of fluid within the soUd bands, often at the nodes of the network of mesoderm. These spaces separate and, as it were, split the two layers of the mesodenn apart</del></div></td><td colspan="2" class="diff-side-added"></td></tr>

The first is the fonnation of the coelom. The mesoderm of the chick is originally a continuous sheet of cells as is shown in Lilly's figure 40, A and B, on page 70 and in Duval's figures 184 to 188 on plate 12. As the cliick grows larger this double sheet of cells forms a plexus with wide interspaces in the network where the mesoderm is entirely lacking leaving nothing but ectoderm and endodenn. </ins></div></td></tr>

The mesodenn on the Ijorders of these spaces gradually flattens into a mesothehmn. The process involves but httle destruction of tissue. At the stage of about six or seven somites a Hving specimen thus shows a double plexus over the area jiellucida, a dorsal plexus which is the developing coelom with large interspaces in the net and many tiny caxities representing the exo-coelom; and a ventral, more massive plexus of angioblasts with much more granular and more refractile c\-toplasm than the mesoderm. The granules of the angioblasts are strongly basophilic and stain intensely with haematox>'lin and with azur. The second structure from which developing vessels must be distinguished I shall call endodermal blebs or bhsters. They are collections of fluid beneath the endoderm, that is between endodenn and mesodenn, which are very frequent in the normal chick. They can be seen in any collection of mounted blastoderms. In the living chick they vary in appearance according to their size and shape. Their margins simulate endothelium to a marked degree. If they are distended and hence round, their margins will be thin, sharp and highly refractile; if they are flatter their walls will be still refractile but thicker. Often their nuclei seem to project into a ca\ity exactly like those of endothelial cells. They may be numerous, small and isolated or large and nmltiple reminding one of midtilocular cysts. .\s can be readily imagined from their structure they may change in shape rapidly, far more rapiiUy than true vessels change. They can be analyzed with the focusing screw both by following their margins over onto the endoderm and by noting their very superficial position. They occur under the ectoderm as well as under the endoderm but I think less freriuently. Xo one can follow the development of blood-vessels in the li\'ing chick without becoming thoroughly familiar with the appearances of these blisters. They have nothing to do with blood-vessels occurring both before the blood-vessels begin and afterward. They are however important physiological structures representing the method by which fluid is absorbed through tiie endoderm and ectoderm for the young chick.</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">* Lilly, F.
