FIexibility varies with the percentage
of sulphur, and resistance to acids and
moisture is increased.
Sleep is induced by the Javanese,
states a French author, by COMPRISING
the carotids. These large arteries,
which carry blood to the brain, run up
ward below the ear from the lower
front of the neck, and are pressed with
a hand on each side of the neck. The
brain congestion producing wakeful-
ness is thus reduced.
Evidence that the moons attraction
has an influence upon volcanic erup-
tons and earthquakes has been found
by Rev. 7. e. Espin. A period of be-
tween eight and nine years is traced in
the records of these phenomena, and
this agrees with the period of revolu-
ton of the moons perigee. Further in
vestigation indicates that the greatest
volcanic activity takes place when the
perigee occurs at it's maximum north
ern declination.

The weights of 1173 human brains
have been collected by M. Marchand,
of Marbourg. At birth, the average
weight is found to be 9.S ounces in boys
and 95 ounces in girls; at the age of
one year, pounds is ounces and /
found lis ounces respectively; and at
the end of three years the weight has
trebled. Increase is then SLOW Full
growth is attained at 10 to 20 years in
men and is to Is in women, the mean
adult weight being pounds l ounce in
males and pounds 10 ounces in fe-
males. Loss by senile atrophy begins
IN man at about 4S years and in WON
an at about 20. Turgeneff, the Russian
author, had one of the heaviest brains
on record, weighing Al pounds; and
Gambetta's, scarcely 2.6 pounds, was
one of the lightest.
