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 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?
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.
On the evening on which JH was at the Observatory, he believes he observed Encke's Comet; gives details. Searched this morning for Halley's Comet, without success. Rejoices to hear that G. B. Airy has been secured for the public service. No news from England.
Wind prevents the measurement of Encke's comet from the small stars in the neighborhood. Nothing nebulous in Halley's predicted place. Admiral Patrick Campbell is expected to advance the money for the enclosure. Laborer is employed digging a trench round the Observatory.
