tains the Energy of a Ton of Pow

Great fire-balls are much more nu-
merous than any one would suppose
who had not paid attention to the sub
ject. Nor need this be a matter of
surprise if it be remembered that
when a fre-ball does arrive it is only
by favorable combination of circum-
stances that any particular individual
is privileged to witness the exhibition.
AS to the brilliant light from some of
these great 6re-balls, there are numer-
Gus statements. We are not infre-
quently told that even the beams Of
the full moon are Intellectual by COM
parison with the blaze of the meteor;
and we find a high authority asserting
that one of these bodies displayed a
flash as ''blinding as the SUM-" But
our knowledge of the actual illu-
minating power of meteors is almost
unavoidable of rather an inaccurate
desert ption. We could measure the
light, no doubt, with all practicable
precision if we knew when and where
to expect it, for then we could bring
a suitable photometric apparatus to
bear at the critical moment. In
the absence of any precise in
formation, we are forced to make
the most of such occasional compari-
sons as may be available. On the
29th of July, 1873, a fire-ba was seen
which created so splendid an illumina-
ton that 1.-The smallest objects were
visible at Manchester. An eye-wit-
ness states that when at it's best the
tire-ball had the luster of a powerful
electric light seen from a distance of
thirty or forty yards, though at the
moment the fire-ball must certainly
have been forty-tive miles away. We
can make a comparative estimate of
the intrinsic intensity of light which,
when received from distance CT forty
five miles, has a brilliancy equal to
that of a known source thirty-fve
yards away. It is thus shown that the
fre-ball must have emitted more light

Fortunate indeed would the astrono-
mer have been who, guided by some
miraculous presence, had gone to the
ancient city of York on the evening of
the 23d of Februry, 1879, and on the
tower of the glorious minister spent
the night in observation of the
heavens. 1t would have been his priv
ilege to have witnessed a majestic
meteor under circumstances of almost
unique magnifcence.
1t was at seven minutes before three
that such few stragglers as the streets
of York still contained saw a pear
shaped ball OF fire travelling across the
sky. 1t drenched the ancient city with
a flood OF light. The superb front of
the minister never bef,re glowed With
so romantic an illumination. The I'M
wOnted brilliancy streamed through
every aperture in every window in the
city, every wakeful eye was instantly
on the alert, every light sleeper start
ed up suddenly to know what was the
matter. Even those whom the blaze of
the midnight light had failed to awaken
were only permitted to protract their
slumbers for another minute and
half. Only until an awful crash, like
a mighty peal of thunder, burst over
the town, shaking the doors, the win
dows, and even the houses themselves.
The whole city was thus alarmed.
Every one started at the noise. But
that noise was not clap of thunder
Nor was it produced by an earthquake.

is, for the source Of the light is not
