The totals for the years and the months in Table IX. are 
expressed in percentages in Tables XI. and XII, and from the latter, 
Chart IV. has been prepared. In this chart, as in the preceding ones, 
the wider columns represent the proportions at Sea Houses and the 
narrower columns those at Beadnell. The males are distinguished 
by the small vertical lines, the berried females by the small portions 
of the columns at the right hand enclosing small horizontal lines, 
and the females not berried by the intervening white parts of the 
columns.
