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 II 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 335
wears that of some palms, ut from QUO
to 700 years; that of an olive tree, at
700 years; of q plane-tree, at 72O OF "
ceder at 500; ofan oak, at 1900; of ayeW,
$3.50: of IL taXodium, at 1000; and OF II
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, DR.. Tr0itski 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 indl-
vidual, smoking produced all accelera-
ton of the pulse-rate and a slight ele-
walton of temperature. Representing
the temperature Of those who do not
smoke by 1000, that of moderate smok-
ers would be 1908, and while the heart
in the former case WAS making lO0O
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 diameiers of less
than ten miles each, and are the
smallest celestial! bodies known, The

round in the same WY in about seven
hours and half Mars turns Oh 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
