ed him that
Mr. ----'s great-grandfather on his mother's side and his own
great-grandfather on his father's side were own cousins. The whole class
of facts, of which this seems to us too singular an instance to be lost,
is forcing itself into notice, with new strength of evidence, through the
galleries of photographic family-portraits which are making everywhere.

In the course of a certain number of years there will have been developed
some new physiognomical results, which will prove of extreme interest to
the physiologist and the moralist. They will take time; for, to bring some
of them out fully, a generation must be followed from its cradle to its
grave.

The first is a precise study of the effects of age upon the features. Many
series of portraits taken at short intervals through life, studied
carefully side by side, will probably show to some acute observer that
Nature is very exact in the tallies that mark the years of human life.

The second is to result from a course of investigations which we would
rather indicate than follow out; for, if the student of it did not fear
the fate of Phalaris,--that he should find himself condemned as
unlifeworthy upon the basis of his own observations,--he would very
certainly become the object of eternal hatred to the proprietors of all
the semi-organizations which he felt obliged to condemn. It consists in
the study of the laws of physical degeneration,--the stages and
manifestations of the process by which Nature dismantles the complete and
typical human organism, until it becomes too bad for her own sufferance,
and she kills it off before the advent of the reproductive period, that it
may not permanently depress her average of vital force by taking part in
the life of the race. There are many signs that fall far short of the
marks of cretinism,--yet just as plain as that is to the _visus
eruditus_,--which one meets every hour of the day in every circle of
society. Many of these are partial arrests of development. We do not care
to mention all which we think may be recognized, but there is one which we
need not hesitate to speak of from the fact that it is so exceedingly
common.

The vertical part of the lower jaw is short, and the angle of the jaw is
obtuse, in infancy. When the physical development is complete, the lower
jaw, which, as the active partner in the business of mastication, must be
developed in proportion to the vigor of the nutritive apparatus, comes
down
