766 SUPPLEMENT TO THE HONGKONG GOVT GAZETTE OF 14TH AUG., 1896.
That the corrections come out so small as those exhibited below, must be attributed to the cumstance, that the screen was well placed. At 10 p. the correction is greater than during the d owing to the minimum of windforce generally occurring about that hour. The corrections are greate when the radiation is great and the humidity low.
Observations sufficient to construct tables for calculating the humidity of the air from observation: made with the rotating thermometer were contemplated by me last year, but were not carried out, want of funds. They will however now be shortly commenced, sufficient funds having been placed my disposal for this purpose.
Corrections to Temperatures observed in Stevenson's Screen in Hongkong, and reduction to meas of 24 hourly readings of true temperature.
