THE FUEL OF THE SUN.

The Author endeavours to demonstrate that the atmosphere o our earth is 
but a portion of the universal medium of space which the earth has accumu- 
lated by its gravitation. The atmosphere of the Sun is calculated on this 
basis, and it is shown that the original evolution of solar light and heat is a 
necessary consequence of the atmospheric accumulation due to his gravitation. 
A continual supply of fresh solar fuel is further shown to result from the 
combined adtion of planetary disturbance and the Sun’s motion of translation ; 
and thus both the origin and the maintenance of solar and stellar heat and 
light are explained. 
All the details of photospheric phenomena, — the spots, the faculae, the 
mottling “ granulations,” &c., &c., follow as incidental consequences ; as also 
the prominences, the corona, the zodiacal light, and the zones of meteors and 
aerolites. 
The atmospheres of the planets are calculated on the same basis ; and this 
reveals a consistent explanation of the observed meteorology of the inferior 
planets, the surface phenomena and specific gravity of the superior planets, and 
the rings of Saturn. 
The phenomena of the nebulae are shown to be necessary results of the 
atmospheric accumulations of certain modifications of star clusters, or great 
solar systems ; and an explanation of the connection between solar phenomena 
and terrestrial magnetism is suggested. 
The whole argument is based upon known and well-established fadls, and 
unaided by any hypothetical assumptions of imaginary materials or forces.

THE CHEMICAL NEWS 
Edited by WILLIAM CROOKES, F.R.S., &c. 
ublished Weekly, price 4 d. Annual Subscription, £1, payable in advance. 
This Journal is devoted to Scientific and Applied Chemistry, and also embraces whatever 
leads to elucidate new discoveries in Mineralogy, Metallurgy, Mining, Mechanics, Elearicity, 
and the collateral branches of Physical Science. It also contains an encyclopedic list of 
chemical papers published abroad during the previous week, with abstradts of all susceptible 
of advantageous abridgment, thus making the two half-yearly volumes, with their copious 
indices, equivalent to an English edition of the “ Jahresberichte.”
