During tho last twenty yonrs The sub.

attracted very great attention, not only
amongst scIonlillo men. but amongst IN.
tclllgeht readers Of ooks and news

Most on readers doubtless know
the chief figures which denote the IT..
mcnslons OF the sun, especially since
the transit 81 Venus eighty years ago led

Gun from the earth, according 10 the
ngurc that had for many ,unrs been nc
'ccpted. hut perhaps not 80 many per.
sons have realized the enormous figures
that represent tho heat of the solar orb,
a. contradict with tho figures that we
are familiar with on the subject OF ter.
restrial heat
Tho volume OF the sun Is about one
million three hundred thousand times
tbst OF the earth, aud lie distance from
tis. In round numbers. about ninety
three millions OF miles. And since we
all OF us every day see the wonderful
effects OF the heat aud Light which oven
this little world OF onrs receives. We
can form some faint Idea Of the cnor.
nous amount Of heat cont nually given
out by tho sun aud the prodigious waste
that must be going On. Aud II We would
form any real estimate of this heat aud
waste, We niHst remember that nil tho
light and heat which Ia received by tho
earth and other planets Ia q very small
proportion OF tho amount that Is being
continually poured forth. 10 might be
Shown with q moderate knowledge OF
geometry. that the amount ~ shed into
spare, whore there are no planets to re-.
CO 70 II, Is two thousand two hundred
and fifty mil Ion times ns great ms that
which IA received b all tho planets
which form our solar system.
We naturally ask What Is the eondl.
tion OF q body which Is capable OF
throwing out for thousands, and PER
haps millions. ~ tears, 80 vast an
amount Of light and hcatP For Il has
been computed that the temperature ~
the surface OF The sun would be ex.
pressed by eighteen thousand degrees

pcrature OF boiling water. This Il about
i've times the highest temperature that
man Is able 10 produce BY artificial

an almost binding b~rilliancy. Or II va

Of the lime-light
SO intense Is tho heat Of the sun that
no lnown substance could remain in q
solid form when subjected 10 such a
temperature Hence i has been con
elnded that the entire orb, vast rs Il i.
Is an aggregation Of gases altogether
void Of any trace OF liquid or solid sub.
stance, moreover. that the outside Wis
ible surface Of the sun lows Ike tho
surface al the sea. OF rather like yapor
Gus masses of cloud and misty air. But
we must not suppose that this vaporous
material Is OF little weight throughout
the whole substance Of the sun; for In
consequence OF the suns vpst sire. the
pressure In the Inward port ons must be

tion that the Internal mass Is believed
70 be dcnser than water. And rs the
late Prof. Clerk Maxwell and Other.
have shown that the viscoslty Of tcnacty
OF . gas increases fast with the rise OF
IT, temperature, Il l. possible tina, the
yaporous matter OF the suns interior

When thinking about this enormous
amountol heat philosophers have nat.
urally inquired whether II Is being dis.
sipated gradually. or whether il Is by
some means sustained undimInlshed.
and u 80 sustained. BY what means.
There have until recently been put forth
two theories on the matter; but recent.
