(Marchand.) the system of true ventricular spaces. Concerning the manner and reason of its formationopinions differ. The older view, that the space represents an isolated portion of the longitudi-nal fissure cut off during the development of the corpus callosum, is sustained neither by itshistory nor by the adult condition of the septum lucidum in many animals in which the partitionis solid and no space Goldstein, however, accepts this view, while Marchand,- His andothers, regard the splitting as secondary. In consequence of the growth, increasing bulk andbackward extension of the corpus callosum and the fusion of the fornix along its under surface,the primary upper part of the hippocampus, which extends well forward along the mesial surfaceof the hemisphere, entir
