These patches of ectopic notochordal tissue are always adjacent to the true notochord. It would appear that there has been some spread of the factors responsible for this particular histo-differentiation, possibly by the diffusion of specific substances from the notochord- rudiment. As Lehmann {Naturwiss. xxi, 737) has recently shown, lithium treatment results in differential reduction of the trunk- notochord in 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 Huxley, Julian, 1887-1975; De Beer, Gavin, Sir, 1899-1972.
