Page 239 - ... apparent motions at right angles to the line of sight and the radial motions as discovered by the spectroscope, still it is interesting to remark that in the case of the stars Castor and Pollux, one of which is approaching and the other receding, their proper motions also are different in direction and in amount ; and further, that y Leonis, which has an opposite radial motion to a and /3 of the same constellation, differs from these stars in the direction of its proper motion.
Page 270 - The most northerly stations are to be found in Siberia, Tartary, and Thibet (which will scarcely be visited by astronomers in December), on the coasts of China, and in North British India.
