Is too busy to use Carl Gauss's magnetometer. Viewing Halley's Comet has interrupted JH's sweeps. Reports that Gamma Virginis is a single star in both the 20-ft. reflector and 7-ft. equatorial.
Reports the birth of his fifth child, Alexander Stewart. Has made some excellent observations of Halley's Comet. Asks CH to inform Carl Gauss that JH has not received Gauss's magnetometer nor is JH certain of how to use it.
Work nearly finished here. Has documented the sixth satellite of Saturn and has seen possibly a seventh.
Confident that 1837 will be his last year in Africa. JH's catalog of nebulae and double stars is nearly complete. Has a series of observations of Halley's Comet from 1836-1-25 to 1836-5-5. Although JH is too busy to undertake any magnetic studies, he has been providing information about Carl Gauss's magnetometer to the new observatory in Bombay. Recalls that Charles Babbage mentioned the 'principle' of Gauss's method 'at least 10 or 12 years' ago.
