As tile fissure is thus ditYerentialed the process of mesoblastic tissue, which from theearliest suggestion of the groove occupies the depression, is correspondingly elongated andaffords a passage for the blood-vessels destined for the nutrition of the interior of the the third month the gray matter, derived from the nuclear layer, is much more voluminousthan the surrounding marginal layer, which, so far as the contribution of nervous elements isconcerned, is passive, since its conversion into the white matter depends upon the ingrowthof axones from the neurones situated either within or outside the cord. The development of the individual fibre-tracts includes two stages, between the comple-tion of which a considerable, and .sometimes a long, period intervenes. The first marks
