The lines 11, 12 and 13 indicate the levels of the respective cross-sections illustrated by the succeeding figures. tined for each tail presented an asymmetrical outline, the lateral wall being considerably thicker than the median. This is shown in part by the right neural tube in figure 8. As the series was followed farther caudally, however, a readjustment of the tube cells was observable, each half now becoming either a solid rod or a tube entirely synunetrical so far as the thickness of its walls was concerned; (see also figures 12 and 18). The neural tube was caused to bifurcate at various levels, dependent upon tlie portion of the hemisphere 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.
