GREAT COMET or 1911
A comet such az the comet of 1911 has around its
head an envelope formed and from either sde OF the
envelope there , bright streak. with dark space
behind the head OF the We don't call Il comet
such as that two-taed comet II IA onetaIlcd
comet with the sides Of the tail exceptionally bright
II we call that tail, where there are Two oflgh,
strcaks a single tail. think we should call TINS tdll
where there are six bright strcaks three-iacd comet
We should regard the two ouer streaks ~ the outer
side of tho second tail. inside the hrst. proceeding
from an inner envelope as IN this ca,, anu mn, sit

Aud then remember what We are 50 apt to forget.

Introduce the subject Of meteors. For long time
neteors were looked phenomena OF our atmos-
phere but facts began to be observed which led to
a different conclusion. One fact that the
meteors occurred in showers on certain
days Take. for instance, the Nov. Is shower.

PERIOD OF The METEOR STREAMS.
As 10 the period In which they travel their II
is a third OF century. That the actual time when
the great display took place Arago being one Of the
ASTRONOMERS who described II most closely, and Hum
DO Described another shower IN l7s If they travel
on their conrse having period OF 50 years, might
account for the recurrence
But this seems too immense. These objects. a few
grains weight have been travelling on such course
OF years which would correspond To course carving
outside Uranus and that seemed 20 Prof.
Newton too grand. and showed that II they Travelled
thirty third part OF the the same course that our
selves would follow, another year they would be
thirty part behind, and the next year another
thirty part behind. and the third year another
tIntyhrd part behind and 90 on until the end OF IS
years, they would be brought TO their place again.
But, meantime. strange fact had been discovered
The comet OF 1861 noticed 70 pass hat part OF the
earths orbit corresponding very closely with the course
IN which the August meteors seem 10 come from,
aud schiapereli said they may lie associated wlth
the comets, and scbiaperelli concluded that the
neeors follow the train VI the comets and snpposina

ete0rs period OF 50 years which before seemed inered

course and That being the the Thought
they would look for comets the paths OF metsors.
They found that comet had been observed mat very
wear 1865, travelling Ia that very course. There WAS
another strange Condolences small comet vss
seen travelling over the course assigned 10

show that the November meteors eau have
