Tillaux states with truth that the basal gan-glia, in toto, are situated above the external auditory meatus and thatthis opening corresponds about to their middle. Between the levels mentioned the island of Reil is situated, forthe exact localization of which additional guides are necessary. G. locates the pole of the island at the punctum Sylrii. A pointon the linea Sylvii 35 mm. behind this indicates the posterior end of PuNCT. ROLflNOICUM SUP. BREGMA Lambda—4L/ Nasion. Jnion Fig. 230.—Location of the Insula and Lateral Ventricle. Island of Punctum Sylvii designates the pole of the island, its posterior end lies onthe linea Sylvii 35 mm. behind this point. The shaded outline of the islandacts as a guide to the basal ganglia, which extend only slightly beyond it, about tothe outer border of the main portion of the lateral ventricle. The lateral ventricleis outlined by a dotted line, its three horns (anterior, posterior and inferior) are alsoindicated in the same way. The fissure of Rolando and Sylvius is indicated withbroken lines. Reids base line (horizontal line of the skull) is the FrankfurterLinie of the German anthropologists. It begins at the lowest point of the inferioredge of the orbital cavity and crosses at the highest point of the upper edge of theexternal auditory meatus.
