MEssRs. EDITORS Peculiarly blessed the college
has been in the efficiency of the ncumbents of her
chair oil natural philosophy she is more than usually
happy Professor LOOMS, who al present nils tue place
vacated by the acceptance by the dslng Henry as
Secretary OF the Smithsonian Institute bids fair to attain
height equal to that occupied by the discoverer oil
electro magnetism, and has already made discovery
that has startled scientific world, and If verified by
future experiment. is destined to exert no small influence
IN the commercial world.
1t is well known fact in physics that if mouse be
placed AN isolated jar OF oxygen gas and then be sub
ected to the influence of the electric fluid, that whenever
spark be elected the spot from whence il comes will
emit light of peculiar nature and color-the latter de-
pending the kind Of electricity developed III the AMI

ing to Frankins theory, then phosphoIescent lurd
light of purpish hue will be emitted this is owing
to the action OF the uld on the hair which is
ducto ing il absorb all the constituents OF the solar
ray except the blue and the red which combine to form
the purple The Tesinous, or negative, bya like action,
the absorption OF all except the blue and yellow,
and consequently the emission OF a similar green light
This light transient only being exhibited at the moment
the spark exoies and heretofore has only been regarded
by scientific beautiful experiment, to exhibit

passage of the current that life becomes extinct 1t

Professor LOOMS, wever, IN course OF experiments
before the Senior Glass, illustrative of electric light,
TOOK occasion 10 exhibit teSe Phenomena on TWO nice,
which enclosed for that purpose in glass jar. To
the astonshnen of himself and the class, however, the
spot on the animal at which the spark exploded
changed to Jet black while the rest of the fur took
milk white color-when tried on the other, the opposite
effect produced the point OF explosion becoming
white and the rest of the skin perfectly blackand these
colors rather absence and presence of every color,
were permanent 1t was phenomena believed to have
never before been Witnessed records OF such fact
can be found AMI afforded subject for the greatest
ercise of ingenuity and most powerful Investigations OF
SCIENCE but the solution, is believed has at last been
found In the Philosophical Hail. in which the expert
ment was performed, the magnet constructed by PROBES
sor Henry--the most powerful in the worlds kept,
and it struck the present professor that to its influence
was owing this surprising phenomena-that is, that by
combination OF the two principles OF electricity and
nagnetsm-by electro magnetismthe change OF color
was rendered permanent. But then the two different
changes were be accounted for. The point of expo-
sion white and in the other black Ex-
pertinent soon solved this, however-for when one
mouse was under the influence of the electric fluid and
black and when the south pole 1t was white land
more surprising still, when the animal was near one
POLE no which, and subject to the positive fluid,
the point of explosion became black while by the mega
tive fluid under the same circumstances it exhibited the
presence of all colors, and was white. The ultimate
laws which these phenomena must be referred, their
occurrence recent TO have allowed the determine

An account has been prepared for the American PhO-
sophca Society," and patent will be taken for the
invention of the manufacture of ermine. which will
doubtless prove very advantageous both pecunay and
Otherwise TO the patenee The discovery deserves on
account of its scientific profundity and practical utility
to rank high among the philosophical and utiarian
transactions of the age SENIOR.
