The Motion of the Moon


    THE American Journal of Science for June contains an interesting article in which Prof. E. W. Brown discusses possible causes for the want of agreement between the moon's observed motion and theory. In his second section Prof. Brown gives a summary of these outstanding discordances:—(1) a secular acceleration 2″. greater than that.due to the change of the eccentricity of the earth's orbit round the sun; (2) a term of 300 years' period and coefficient 15″; (3) a term of 60 years' period and coefficient 2″.
