...the aberration or difference between the true and apparent place of a fixed star, is occasioned by the progressive motion of light, combined with the motion of the earth in its orbit ; and that this aberration when greatest amounted to 20 '232. Now the earth describes an arc of 20"-232,...

...vary as the sine of the star's latitude. This apparent motion of the stars arises from the velocity of light combined with the motion of the earth in its orbit. The sun is so very distant, that his rays are deemed parallel ; therefore let S'A . SB, fig. 116, be...
