No. H. 55, an apparently normal skull, of which tlic vault only is preserved, has a normal 

 index of 78.72, but it is aberrant as regards the rest of the group by reason of its niuch greater 

 size and difterent configuration. 



No. 11.2.3, liaviiig lowest cej)halic index, lias n.-xt lu lowest veitico-transverse index. The 

 lowest vert ico- transverse index is in the skull of a child.
