Source of text:
TxU:H/L-0581.4.b; Reel 1058
Summary:

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.
