[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.
