THE FUEL OF THE SUN.

8 vo., Cloth, Price 7 s. 6 d. 
The Author endeavours to demonstrate that the atmosphere o four 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 ana 
light are explained. . . , 
All the details of photospheric phenomena, — the spots, the faculae, the 
mottlino- “ granulations,” &c., &c., follow as incidental consequences ; as also 
the prominences, the corona, the zodiacal light, and the zones of meteors and 
aC The atmospheres of the planets are calculated on the same basis ; and this 
reveals a consistent explanation of the observed meteorology of the interior 
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 g rea 
solar systems ; and an explanation of the connexion between solar phenomena 
and terrestrial magnetism is suggested. . , 
The whole argument is based upon known and well-established facts, and 
unaided by any hypothetical assumptions of imaginary materials or forces.
