SCIENTIFIC MIsCELLANA'


Experiments by NJ. Pasteur In vac
cination for splenic fever have proved
entirely successful. The new vaccine
matter can be cultivated at pleasure,
transported without injury, and pre-
serves the animals, into which 1t is In
troduced from a mortal disease.
Ninety-two pupils have been enrolled
In the Sunday Science school. Of Edin-
burg. Scotland, and from November to
to July last the institution had an aver
age attendance of sixty young people
whose late business hours prevented
their attending the evening classes.
According to q French entomologist,
the wool of different countries may be
distinguished In market by the varieties
Of beetles which inhabit the bales. He
has Unidentified AZ species in Australian
wool; 50 in South African wool; 80 in
South American wool; 1G in Spanish
wool; and 9 In Russian wool.
AS upwards of Ave hundred tons Of
sugar made from starch are daily placed
In the market, Prof. Wiley suggests
the d~esirability of giving the substance
a distinctive NAME. He proposes the
name amylose, from the Satin amylum,
starch. "Amylose" will include all sug-
ars and syrups made from starch.
Cyclones are observed to extend over
IA circle from 100 to 500 or, sometimes,
1000 miles In diameter. In the West
Indies they are sometimes rs small as
100 miles in diameter, bit dilate to 500
to 1000 miles on reaching the Atlantic.
They sometimes, however, contract,
increasing greatly in violence during
the process.
Some remarkable and suggestive pecu-
liarities are found in a human jawbone
from the Schipka Cave Of Moravia.
stone implements found with the bone
indicate that 1t belongs to the stone
age. In development the jaw is that
Of u child, but it is of great size. Its
shape indicates the absence of any chin
and has other peculiarities found in
greater degree in the higher apes.
Experimental measurements Of the
temperature of the body baye led NJ. E.
Wharf to the conclusion that the lowest
temperature in man, ensuing after a
period Of rest, is 9s.4 degrees; that tie
temperature increases, under the in
fluence of a positive, ascending effort,
TO 100. 9 degrees; under the influence
of a descending effort to 100. 8 degrees;
that 1t increases after any exertion,
but more after an ascending than after
"a descending one; and that the chemic-
al actions Of the organism are augment
ed after every movement.
Physically, the nearest approach to
nan In the lower animals is the anthro-
poid ape; but in intelligence ants seem
to rank highest in the scale below man.
Reference has often been made to the
habits Of species Of these insects in con-
Quoting battles. capturing slaves, and
their power of recognizing friends and
Of communicating among themselves.
Various entomologists have shown
them to possess reasoning powers quite
surprising. One of their most remark
able habits is the practice of many
species of keeping aphides, as men keer
milch-cows. to supply a nutritious Sc.
erection. Huber first::observed this habit,
and noticed that the ants collected the
eggs Of the aphides and treated them
with as much apparent care as they
treated their own. When these eggs
hatch out, the aphides are usually kept
and fed, bg the ants. Sometimes the
stems and branches on which they live
are encased by the ants In clay walls,
In which doors are left large enough to
admit the ants but too small to permit
