CHAPTER II.

The moon cannot have even an imaginary rotation on its axis,

but is generally believed to have.

Quotations to prove this 33

Proofs that there can be no rotation. The most confused

assertion that there is rotation shown to be without

foundations 35

A gin horse does not rotate on its axis in its revolution 37

A gin horse, or a substitute, driven instead of being a driver 38

Results of the wooden horse being driven by the mill 38

The same results produced by the revolution of the moon.

Centrifugal force sufficient to drive air and water

away from our side of the moon 39

That force not sufficient to drive them away from

its other side 40

No one seems ever to have thought of centrifugal force in

connection with air and water on the moon 41

Near approach made by Hansen to this notion 41

Far-fetched reasons given for the non-appearance

of air and water 42

The moon must have both on the far-off hemisphere 44

Proofs of this deduced from its appearance at change 44

Where the evidences of this may be seen if looked for

at the right place. The centrifugal force shown to

be insufficient to drive off even air, and less water,

altogether from the moon 45

The moon must have rotated on its axis at one period

of its existence 47

The want of polar compression no proof to the contrary 48

Want of proper study gives rise to extravagant conceptions,

jumping at conclusions, and formation of

"curious theories" 48
