to the possibility Of making the deaf and dumb speak In
this connection it may be well to say few words to the
circumstances under which this result has been attained

been contended for long time A Spanish writer had
written ably on the subect but still the problem remain
ed to be solved by practice.
About the year 1926 the celebrated naturalist and
phanthropist Etenne Geofroy Saint Haire interested
himself particularly in this question of teaching the deaf
and dumb He was decidedly of opinion that they could
be taught to speak, He showed that their organs of speech
were as perfect those of other people, and argued that
was only necessary to give proper instruction as to
their use.
Encouraged by this opinion, NJ Dubois undertook the
education OF his child and finally not only taught him the
art Of speech but established him professor teach
it to others in deaf and dumb institution which he 1.-THE

1t would seem from the following notice taken
from the Moniteur of Saturday last that the slight
modification in the government Of this country, con-
sisting chiefly in the change Of the Prince Louis
NAPoLEoNs title from President to Emperor, is not
to be effected so soon as all the world believed and
as your correspondent has repeatedly predicted The
note in the Moniteur, evidently emanating from a
member of the Cabinet doubtless acting by order of
the Prince himself, says:
Several foreign journals are striving TO accredt the
report that the Northern Powers in anticipation Of
tain contingencies prepared to the coalition of
1915; and that they have in advance determined the
limits beyond which France would not be permitted to
