Animals have been called warm
blooded and FLOODED, but the dis
tinotion is less sharply drawn than
was once supposed, as one class grad
yates into the other. In a paper to the
Royal Society of Victoria. Mr.. Alex
ander Sutherland mentions that the
invertebrates have the capacity of pro-
duclng heat. although they are cold
blooded, but except the insects, their
temperature seldom rises more than a
fraction of n degree above that of the
medium in which they live. Certain
Northumberland as polypi, molluscs
and crustacea-raise themselves one
third of n degree to degree above
their environment. Insects. though
essentially cold-b looded, are usually
degree or two warmer than their
medium, but capable of remarkable
warming with exertion. Fishes, am
phibla and reptiles also heat them
selves on moving. A species of blind
worm is said TO rise as much as Ii
degrees above the temperature of the
air. The warm-blooded animals have
nearly fixed temperatures, and do not
vary with the air. the monotremes-
the lowest in the scale of mammals
having temperature of about II to SO
degrees, while the marsupluls average
about SO to 81 degrees and the average
of the higher orders seems to be from
30 to 1O4 degrees. Birds range between
1903 and los degrees, In very general
way. it may be said that bodily ac-
tivity depends upon body tempera-
lures.
The aurora boreals according to the
theory of Herr Gustav Wendt, may
be regarded as an electrical phenome-
non arising when oxygen and other
paramagnetic matter-or matter as

of the atmosphere, thus setting up
electric currents.

The magnetarlum is wonderful ap-
paratus lately shown the French
academy by NJ. Wilde. 1t Is intended to
reproduce the phenomena of terrestrial |
magnetism and the secular variations
of the compass and dipping needle. One
terrestrial globe is made to revolye
within another. The inner globe is
wound with insulated copper wire, and
the surface of the seas IS covered with
thin sheet iron, to give a difference be-
tween the magnetism of land and
water. Insulated rings revolving with
the axes carry copper brushes, which
cause electric currents TO pass around
the surface of the globes. A dlfferential
motion is impaired TO the inner globe
| by an arrangement of eplcycloidal
| toothed wheels, and the result Is an ac-
curate reproduction of the principal
phenomena Of terrestrial magnetism,
and the changes that have taken place
during the last three centuries at Lon
don. the Cape of Good Hope, Saint
Helena and Ascension Island. The in
CAPABILITIES in the periods of magnetic
| dip, as well as the unequal rates OF
| change, are faithfully shown.
