son, conservator of forests for south
ern Nigeria, indicate that the mahog-
any tree grows much more rapidly
than the number of so-called annual
rings suggests. Mr.. Thompson thinks
that they show three or four we'll
marked zones of growth each year, cor
responding to the fou,' seasons. Both
forest trees and those grown in the
botanical garden exhibit the same phe-
nomenon. On the site of the town of
Ijaye, destroyed sixty years ago, a
forest has grown up containing mahog-
any trees with trunks exceeding ten
feet in girth.
Electric baking ovens have long
been available, but their use has not
spread very rapidly, probably because
of the cost, or the difficulty of pro-
curing the requisite current. In the
little Swiss town of Kerns, where cleo
trio power is cheap, the electric bak-
ing oven has just been established in
satisfactory manner In a furnace
less than eight feet long 100 pounds
of bread. in loaves of one and three
pounds each, can be baked at one
time, and eight bakings can be made
in twelve hours. The cost of the heat
ing is little more than one cent and
three-Quarters per pound of bread.
The brain of the celebrated chem
Mandnlonf
studied by Professors w. Won Becht-
crew and R. Weinberg. 1t was above
the average size, but not remarkably
so, the weight being 1871 grams
about so 2-3 ounces. The convolutions
were found to be simple in arrange
ment, and from mere examination. it
is said, no one could have formed any
opinion of the very special qualities
manifested by its living possessor.
Only two features were in any de-
gree peculiar-a highly convoluted
part of the left parietal lobe and a
comparatively small and simple tenn
poral lobe. For comparison it may be
recalled that Cuvier's brain is said to
have weighed 641h ounces and Gam
betta's only SO ounces.
In recent lecture before the Inter-
national Congress of Applied Chemis-
try Sir Boverton Redwood enumerated
the principal advantages of petroleum
as fuel. Its thermal efficiency as
compared with coal is reckoned by the
British Admiralty as IS to 10; it does
not, like coal, demand that thick bed
Of incandescent fuel be ready before
active combustion is produced; it is
relatively clean, and requires little Ia
Dor; 1t is admirably suited to fueling
vessel at sea by simple flexible
pipe the combustion can be controlled
with precision, and quickly brought
to the highest efficiency or cut off en-
tirely. Still, the lecturer thought that
liquid fuel will never entirely displace
coal, because the supply is not likely
to be sufficient.
An interesting example of the way
IN which modern seismographs detect
the location of earthquakes occurring
Is afforded by what happened on Octo-
ber %. Prof. Milne at the Isle of
Wight noticed shocks whose point OF
origin was about so degrees distant,
corresponding to the distance of ia
pan, San Francisco, and Mexico. He
thought it possible that the true point
was in the east. At the same time
Prof Belar at Laibach, Austria, no.
ticed the shocks, and declared that the
center of disturbance must be about
$3.50 miles to the east. The next day
the telegraph brought the news of
great earthquake, which had occurred
at the time of the observations in
Baluchistan, the town of Belput hav-
Ing suffered severely.
