The hippocam- pus major penetrated into the middle lobe, at the bottom of which it terminated by a rounded extremity. On its side, I observed the depres- sion already described (PI. XIII. fig. 1, e), and into which a considerable fold of the pia mater dipped. I should also remark, that the longitudi- nal fibres of the great hippocampus expanded in the prominent portion of the middle lobe, where they united with those proceeding from the crura cerebri. The nerves, very voluminous in proportion to the mass of the brain, were very evident. I have represented them in Plate IK. fig. 1. EIGHTH MONTH.* I now proceed to the description of the brain of a foetus of thirty-four or thirty-five weeks. As this organ is already completely formed, in respect to the configuration and structure of its
