purpose in question the aspect and the shade must be the same
throughout. Group portraits would do to work from, were it not for
the strong out-of-door light under which they are necessarily taken,
which gives an unwonted effect to the expression of the faces. Their
scale also is too small to give a sufficiently clear picture when
enlarged. I may say that the scale of the portraits need not be
uniform, as my apparatus enlarges or reduces as required, at the
same time that it superposes the images; but the portraits of the
heads should never be less than twice the size of that of the Queen
on a halfpenny piece.

I heartily wish that amateur photographers would seriously take up
the subject of composite portraiture as applied to different
sub-types of the varying races of men. I have already given more
time to perfecting the process and experimenting with it than I can
well spare.



BODILY QUALITIES.

The differences in the bodily qualities that are the usual subjects
of anthropometry are easily dealt with, and are becoming widely
registered in many countries. We are unfortunately destitute of
trustworthy measurements of Englishmen of past generations to enable
us to compare class with class, and to learn how far the several
sections of the English nation may be improving or deteriorating. We
shall, however, hand useful information concerning our own times to
our successors, thanks principally to the exertions of an
Anthropometric Committee established five years ago by the British
