On the left side, the Lobus superior nowshows a dorsoapical swelling over the apical branch of L. 2 (Fig, 18,L. 2), which indicates the beginning of the portion of the left upper lobe,which substitutes for the Lobus superior on the right side. The fissurebetween L. 2 and L. 3 on each side deepens, while the Lobus inferior onboth sides shows a series of projections over the several branches of thestem. On the ventral surface, V. 3 is indicated: on the lateral border,.
