Above London the water OF the
Thames is found to hold in solution
two cubic inches of oxygen gas. per
gallon. while near the point where
the city's sewage is discharged it con-
tains ouly about half cubic inch.
A little lower down, however, the
river RECEIVERS nearly its original pro-
portion of oxygen.
Botanists have evidence that trees
may attain very long lives. The age
of an elm has been estimated ut $50
years that ofsome palms, ut from GU
to 700 years; that of an olive tree, at
700 years; of q plane-tree, at 72O OF u
ceder at 500; ofan oak, ut 1900; of ayew,
$3.50: of u taxodium, at 1000; and of ~
baobab-tree, at 5000 years.
Recent experiments on dogs have
shown that the hypodermic injection
of solution of theme, the active prin-
ciple of tea, almost instantly counter
acts the effect Of morphia, animals
having been revived after the action
of the heart had ceased to be percepti-
BILE, Similar properties are possessed
by catfenine, the active principle OF
coffee, but it operates less quickly.
The danger of tobacco-smoking is
manifested, Dir. 'froitski thinks, in its
effect upont he action of the heart.
During series of observations he
found that in every case, varying ac-
cording to the condition OF the indi-
vidual, smoking produced ali accelera-
ton of the pulse-rate ahda slight ele-
walton of temperature. Representing
the temperature Of those who do not
smoke by 1000, that of moderate snlok-
ers would be 1908, and while the heart
I'm the former case WAS making 1000
pulsations, in the latter it would beat
1850 times.
The two tiny satellites of Mars.
which were discovered by Prof. Asaph
Hall in 1877, have diameters of less
than ten miles each, and are the
smallest celestial bodies known. The
outer one-I2, 600 miles from the planet
completes Il revolution i'll its orbit
in about thirty hours in a direction
| from west to cast, and the inner moon
about $500 miles from the planet-goes
round i'm the same Way in about seven
hours and half Mars turns on its
| axes in twenty four and a half hours
from west to east. One moon there
fore travels slower than Mars and rises
for him in the east, while the other
outruns him and comes up in the west.
When an impression, " says DR.. r.
Wood Brown, }" is received upon the
retina, tympanum, tongue, fingers OF
olfactory bulbs, it is conveyed by
proper nerve filaments to cells in the
gray matter of the brain. Thes,' cells
yibrate from eXcitation and undergo a
change, say that of molecular arrange
ment. Ifthis impression is repeated
often enough, the molecules are perm
antly changed, and we have memory
cells and remember the impression.
But repeated impressions are not al
avs necessary to produce . memory
cell. A sudden violent eXcitation will
cause a permanent change in CELL
