In the dry soil of Egypt Prof. G.
Elliot Smith finds the brains OF most
non-mumified bodies Of the cemeteries
have been naturally preserved even
from predynastic times. The convolu-
tions may be mapped, and an account
is soon to be given of the brain struc-
ture of Egyptians Of different periods.
A file specially designed for work
ing on gun metal Is being used in
French machine shops. 1t has shallow
diagonal channels, at intervals of half
an inch, the teeth being on the raised
portions between the channels. 1t Is
claimed that these files. clogging much
less rapidly than others, increase the
work done by about fifty per cent
No white pigments have been found
in feathers, and the whiteness of white
feathers Is ascribed to total reflection
Of light from their exposed surfaces.
Some have supposed the reflection to
be from air spaces, or bubbles, in the
feather structue, but r. NJ. Strong, of
Haverford College says that the white
effect is powdered glass, upon the
small size of the structural elements.
These have large number of surfaces
80 placed for any position OF the eye
that there Is maximum reflection to
the eye. and almost no absorption by
the unpigmented feather substance.

A remarkable example of the power
of mimicry possessed by some persons,
but altogether lacking in others, was
furnished by the late Professor
Roberts-A usten. of England. His
friend. Prof. T. e. Thorpe, recalls
many interesting instances of Roberts
Austen's singular gift. which was pur-
posely exercised only occasionally for
the entertainment Of his scientific con-
freres at club meeting. But what
lends special interest to the case was
the fact that Roberts-Austen frequent
ly exercised his power without being
aware of it. III have heard him, to my
terror" says Professor Thorpe. 'in the
course Of a conversation gradually
copy the tones and infections of a
mans voice. and have seen him re-
produce his manner to his very face"
In such cases there was no conscious
ness of what was being done in the
mind of the mimic. or on the part of
the person initiated. and Professor
Thorpe believes the origin of the un-
intended mimicry was sympathy alone.
