Abstract
THE most interesting result of Prof. Newcomb's researches on the planetary inequalities in the moon's motion is that he has found 1″-14 as the theoretical coefficient of the Jupiter evection term. This term was discovered empirically by Prof. Newcomb in 1876, and Mr. Nevill assigned its origin to Jupiter. Dr. Hill and Radau independently computed its coefficient as 0″.9. Two or three years ago it was pointed out that the observations indicated a coefficient 1″.1, and now Prof. Newcomb has obtained the same result by theory. This term is now worked out; the subject begins and ends with Prof. Newcomb, and has lasted thirty-one years. No indication is given in the memoir before us as to why Hill and Radau concurred in an imperfect value. It was a curious incident, as we know of no other case where any result of either of these two mathematicians has required revision.
