The Mosaic account of creation, the miracle of to-day; or, New witnesses to the oneness of Genesis and science To which are added an inquiry as to the cause and epoch of the present inclination of the earth's axis, and an essay upon cosmology . gravity. It is evident that the solar attraction can notproduce any movement, since its influence nponone part is counterbalanced by another symmetri-cally placed. If the axis is perpendicular to the ecliptic, theattraction of the Sun upon a polar upheaval will beequally without effect, since no internal movementcan change the position of the centre of gravity(Principia), and a polar upheaval would necessi-tate a sufhcient movement of the remaining massin the opposite direction, to keep the equilibriumundisturbed, while the intensity of the attractingforce on each molecule would be unchans^ed. But if the axis were sensibly inclined, say 5° 9,and the sphere elongated in the same direction(i. e. a polar upheaval), then one pole Mould benearer the centre of attraction than the other, andacted upon with greater intensity. Hence itwould be drawn towards the ecliptic precisely in 220 INCLINATION OF EARTIls AXIS. the same manner and for the same reason as isnow the equatorial FiGUKE 2, Let Fig. 2 represent a homogeneous sphere,with axis PP inclined to the ecliptic, S being theSun. Suppose the sphere to be elongated, asrepresented by the dotted lines. Then, since P isnearer the Sun than P, it will be attracted morestrongly, and consequently drawn down to theecliptic, and if no force opposes, its momentumwill carry it as far below, until stopped by theaction of S, when it will return to the ecliptic, and60 vibrate back and forth like a pendulum. An equatorial protuberance, for simiUir rea-sons, would be an opposing force, which beingnull when the equator coincides with the ecliptic,increases as the ang. SOE increases, until, be-coming equal to the turning force exerted by CAUSE FOR INCREASE. 221 P and P, the system aga
