Believes that TM is the first to see the return of Halley's Comet [see TM's 1835-9-1].
Has been observing since 3 a.m. and his fingers are powerless with the cold. Observed a star group, which may be Halley's Comet. Comments on the working of his telescope. Has JH placed his 20-ft. telescope in position for the Blueberg Mountains?
Living quietly on the ship and eating good food has been good for him. He longs for home. Peru is in a miserable state.
Accepts JH's suggestion about using the offered money for publication costs [see JH's 1835-6-12]; is concerned about the telescope at Cambridge, as G. B. Airy has left for Greenwich; final comments on the comet's effects and the weather.

Sorry to hear he had such wretched weather for their jaunt. The violent winds overturned his 14-ft. reflector and split the tube. Has obtained a capital tent for the Cape. No news from England. Commences the solar observations tomorrow, if fine.

Comments on CW's work on light and on the velocity of electricity. JH's ruminations lead him to the idea of motion pictures.

Has been unable to do any observations owing to ill-health and lack of an observatory owing to change of residence. Sends his paper on double stars. Pleased to hear everything progresses at the Cape. Will be happy to hear from him.
Received a newspaper from England, which gave news of a comet. A ship entered Table Bay in the night; she may be from England.
Sends information about where to look for Encke's comet.
Is grateful for J. F. Encke's letter. JH's suggestion of the 14-ft. reflector was anticipated for Halley's Comet. Wishes that JH's aunt could visit the Cape.
Sending a copy of the memorandum he made of the first mirage he has ever seen. Describes various points. Much obliged for J. F. Encke's Ephemeris; his writing reminds TM of Isaac Newton.

Has received the printed copy of JH's observations on nebulae from Naples. Hopes JH will return to England via Sicily.
