1) In considering the drawing it must be borne in mind that the oblongata of 
the Alligator is markedly bent and that the direction cf the section has been 
chosen perpendicular to the base on the level of the VIl-root, so that the caudal 
sections are not perfectly perpendicular to the longitudinal axis of the oblongata. 
In Figs 6, 7, and 8, the dorsal half represents a more eatdal level than the 
ventral half. .
