CHAPTER XII.

Some of the results arising from the sun's being

a hollow sphere 215

Repetition of the effects of condensation on the

temperature of the nebula 216

Ideas called up by the apparently anomalous increase

of temperature 217

How heat is carried from the sun to the earth 218

The sun supposed to radiate heat only to bodies that can

receive and hold it, and not to all space. The heat

of the sun accumulated in a hot box to considerably

beyond the boiling point of water 219

The heat accumulated in this way supposed to be due to a

peculiar function of the ether, as it is a fact that

heat can be radiated from a cold to a hot body 220

The sun must be gaseous, or rather gasiform, throughout.

No matter in it solid or even liquid. Divisions and

densities of shell 221

The hollow centre filled with gases, whose mass naturally

diminishes the mean density of the whole body 222

The amount of this reduction so far defined. The presence

of gases or vapours in the hollow a natural result

of condensation 223

The hollow centre filled with gases not incompatible with

the sun's being a hollow sphere. The temperature at

the centre may be anything, not depending on any

law of gases 223

Further exposition of hollow-sphere theory put off till after

further development of the construction of the sun 224
