SCIENTIFIC NOTES.

Steel tubes are found to retain twice as
much magnetism as steel rods, and are
therefore better for permanent magnets.
Manganese must be widely diffused in
nature. 1t has been found in 81 samples of
wine, in cereals, and in almost every de-
scription of rock.
Puscher, the Nuremberg chemist, says q
paste composed of starch, glycerine and
gypsum will maintain its Elasticity longer
than any other cement
n. B. Clark proposes, i'll the Journal Of
the Franklin Institute, to employ, as L

In railway building across sandy deserts
the French engineers are beginning to en-
ploy iron ties. A late pattern consists of 4
wrought iron bar supported in the middle
and at both ends by globular plates of cast
iron.
A German invention, it is said, will pro-
tect iron from rust Ordinary oil paint
mixed with 10 per cent. of burned magne-
sia, baryta or strontia, as well as mineral
OIL neutralizes the free acid of the paint
and the alkaline reaction protects the iron
from rust.
There is less blood in cold blooded than
in warm blooded animals. The larger the
animal the greater is the proportion of
blood to the body. Man has about a gallon

Ten quarts of normal alcohol have been
made from six pounds of watermelon pulp.
Free sulphuric acid was added, the mixture
was warmed, and the sugar was changed
into glucose and levulose. This product
ferments directly.
Luminous waterproof paper may be
made from mixture of 40 parts pulp. 10
parts phosphorescent powder, part gela.
tine, 1 part potassium bichromate, and 10
parts of water. 1t can often be used where
luminous paint cannot.
The toad frog and chameleon capture in
sects by darling out the tongue, which is
tipped with glutinous saliva. The boa con-
stricting serpentS crush their prey i'll their

1t has recently been proposed to prevent
petroleum fires by placing bottle of am

but not always located in the head In the
clam it is found at the base Of the foot :;
some grasshopperS have it i'll the fore legs
and in many insects it is on the wing
HOLSTERS and crabs have the auditory sacs
at the base of tie antenn9.
An engineer in Michigan has invented
an attachment to steam cylinders which
