Acknowledgement of paper on Hansen's theory. AC's treatment of Lunar theory by method of variation of elements is new; outlines the possible difficulties. JCA is applying this method to the secular inequalities of the moon's mean motion, further to paper in PTRS, 1853.

[JCA's comments on De La Rue's speech on awarding Gold Medal of RAS] Acknowledges copy of Hansen's letter sent. Disagrees with H's assertion that he never contested JCA's theory of the secular acceleration of the moon: H caused LeVerrier to attack JCA and Delaunay, and is now adapting his own theory without admitting it might be wrong.

Letter of introduction for Pierce. Plana convinced of JCA's and CD's expression of the secular acceleration of moon's mean motion. Hansen and LeVerrier might yet be convinced.
