or its object the
fostering a love of the country districts and stemming the exodus to
the cities, which is a disquieting feature of life in the
Commonwealth, medical inspectors in the schools of Victoria have come
to the conclusion that blue-eyed people seek the land, and that the
city populations are recruited largely from the brown-eyed. If this
conclusion could be generally supported, it opens up interesting
questions as to the connection of eye-pigmentation with race, and its
possible modification by inter-marriage. From the uncertainty of our
knowledge as to the immediate cause of eye and hair pigmentation one
cannot but be faced with the alternative--either that little formal
attention has been paid to the subject, or that the elements of
investigation are uncertain and conflicting. What would Mendel have
said to this problem?

APPENDIX C

In the course of the compilation of this History, the Author
re-perused the _Handbook to the Roman Wall_, in the fifth edition,
put forth by Mr. Robert Blair, many years after the death of the
original compiler, Dr. Bruce. In the light of succeeding events it is
curious to note what is said of Corstopitum, a site noted in the text
as being near Hadrian's great line of wall and its defences. Thus the
record runs:

This site, which lost its military importance with the retreat of the
Romans, apparently became a commercial emporium, and underwent very
various fortunes, culminating in its destruction by barbarians; so
that, from the fifth century, it ceased to be from that day to this;
no man dwelling on the site.

Mr. Blair says of the place itself:

Its form and extent gave it the aspect of a city rather than of a
camp. Remains of a bridge across the Tyne are to be seen when the
river is low. Excavations were made in the summer of 1906. Nothing of
account was found except a few walls, an intaglio, some fragments of
pottery and a few coins.

How frigid and disappointing is not this record! But listen to the
story which Sir Arthur Evans related to the British Association for
the Advancement of Science in his Presidential address at Newcastle
last September:

The work at Corbridge, the ancient Corstopitum, begun in 1906, and
continued down to the autumn of 1914, has already uncovered
throughout a great part of its area the largest urban centre--civil
as well as military in character--on the line of the Wall, and the
principal store-house of its stations. Here (tog
