Abstract : The Main Problem of Lunear Theory has been solved in a completely literal form; at places the development reaches terms of order 21 in the secularized Hamiltonian. In order to assess the accuracy reached in this manner, the constants are given the numerical values they have in the Improved Lunar Ephemeris and the series for the mean motions of node and perigee are evaluated. There is agreement on the principal parts within 13 per Julian century with Brown's values as modified by Eckert. (Author)
