The hydranth had fallen to the bottom of the dish. cylindrical or flattened epithelium cells of ectoderm and ento- derm of the normal individual have now assumed a spherical form. In the iron-alum stain, the nuclei appear for a time nor- mal, but later distinct changes, undoubtedly pathological, have set in. There is no indication of an absorption of such cells into the lower portions of the stems as Cast and Godlewski (/. c.} have described for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
