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
