heavy lower jaw, the downward gravitation l of which has been 

 counterbalanced by a backward rotation of the brain and its con- 

 taining case. The fronto-inial and fronto-postremal diameters are 

 identical, so are the maximum height and the maximum width; 

 the point for the latter measurement lies low down on the parietal 

 bones, on a level with the posterior superior angle of the squamous 

 part of the temporal bone, and in a plane which would touch the 

 anterior edge of the faintly marked tubera parietalia. There is 

 a considerable downgrowth of the occipital condyles, as is often 

 observed to be the case in skulls with heavy lower jaws, especially 

 in the later half of life ; the skull however is supported by the con- 

 ceptacula cerebelli and the grinding edge of the molar teeth when 

 it is placed upon a flat surface without its lower jaw. The extent 

 of its cranial curvature is spoken to by this last fact, as also by the 

 lowness of its basilar angle, 14, as obtained by the occipital gonio- 

 meter of Prof. Broca. In the occipital and vertical normae this 

 skull shows the rounded outlines characteristic of well-filled skulls. 

 In the latter of these normae it shows the characteristic proportions,
