The measurements[16] offer many points of interest, although, so far
as the vault is concerned, they are considerably interfered with by
artificial deformation in some of the specimens. As in certain former
reports by the writer, they will be dealt with in order according to
their significance.
[16] All measurements presented in this report were taken personally
by the writer, with proved instruments and due care. Unless otherwise
noted, the methods follow strictly the international agreements of
Monaco and Geneva.
