With readings from: an uncorrected barometer; its attached thermometer; dry and wet thermometers. These are followed by: detailed observations of computed temperature of dew point and tension of vapour [on unused tables for electrometer observations]; maximum and minimum temperature, solar and terrestrial radiation and Moon's age; corrected barometer; and an abstract of daily triple observations of the magnetometers. The observations conclude with proportion of sky clouded, mean direction and force of wind by Lind's gauge; and the daily amount of rainfall. Columns for temperature of dew point and elasticity of vapour [p.12] are left blank.
Observations were suspended for the period 10-21 October, with the note: '...on account of removal of the Instruments into the new building'.
Headed 'Abstract of daily Observations...'. The tables have various explanatory annotations. |
