FIG. 7 Figs. 7 to 13, inclusive, are a series of semi-diagrammatic figures which illustrate the development of the jugular lymph sac of the left side, but answer as well for the sac of the opposite side, since it is developed in exactly the same manner. The stippled area indicated on the figures (Figs. 7 to 11, inclusive) represents the portion of the venous system which is subsequently split off from the main venous channels and which becomes transformed, through growth and fusion and after the evacuation of its blood contents, into the definite jugular lymph sacs. It may be stated at the beginning that the lymph sacs present a remarkable variation as regards the details of their development, not only in different embryos of the same stage, but even upon opposite sides of the same embryo. It will therefore be necessary in this brief outline to give a more or less composite description of the conditions which may prevail at any given stage rather than those which invariably 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 Bardeen, Charles Russell, 1871-1935, ed; Boyden, Edward A.
