Abstract of the Results of the HourZ_1/ Meteorological Obse-rvations
taken at the Sm-veg/or G-eneral’e Ojice, Calcutta,
in the month of’ May, 1862. '

Hourly ‘Meuns, &c. of the Observations and of the Hygrometrical elements
dependent thereon.

The Mean height of the Baronlet-61-, as likewise the Mean Dry and Wet Bulb

Thermometers, are derived from the Observations made at the several hours
during the month.
