Thanks for signing certificate for [C. M.] Elliott. Sends extracts from George Buist's history of heat storms in India, with evidence of great masses of ice dropped by these storms.
Glad that Dr. [Duncan] Stewart received promise from Mr. Prinsep of cadetship [in H.E.I.C.] for Stewart's son. WS cannot promise same for young [George] Maclear but will add Maclear to list of applicants for WS's patronage.
Describes travels abroad and their educational value, news on balloon ascents, barometer corrections, Henri Regnault's hygrometer, invention of electric weaver and other new applications of electricity throughout Europe.
Plans date and time for first ascent of balloon experiment. WS's daughter has fallen in love with JH's son William.
Discusses balloon experiments to explain fall of barometer with humidity, and explains more discrepancies in vapor-pressure observations. Mentions new 'Hygrometric condenser' as an alternative to wet bulb experiments.
Urges renewal of high balloon ascents with periodic observations both to further knowledge of law of decrement of temperature and pressure and for 'ulterior investigations.'
Regrets missing JH's visit; discusses influences of atmosphere and solar position on Indian weather and difficulty it causes in obtaining meteorological laws.
Clarifies results of pressure oscillations on two coasts of India as similar despite different weather conditions, and deems results thus unsatisfactory; explores reasons and suggests solutions for lack of success.
Noting discrepancy between dew points obtained by wet bulb and direct methods, WS cannot say which is nearer the truth; suspects that both have inaccuracies.
