Contrasts EC's catalogue of comets with that of J. F. Encke.
Confirms measurements of a transit circle.
Thanks EC's for EC's observations made with EC's excellent telescope. Discusses Eta Coronae, Gamma Virginis, EC's drawing of M51, and whether Orion changes, stating that JH is 'no believer in rapid changes in Nebulae yet there may be changes....'
Would like to know where he can obtain JH's observations on double stars. His own recent observations of planets.
