The corrections −0·2 and + 0°6 have been applied to the readings of the self-registering max. and min. air-thermometers to reduce them to the readings of the standard.

Readings of Two Self-Registering Maximum and Minimum Thermometers placed
above the Tower of the Radcliffe Observatory, at an elevation of 105 feet, (reduced
to the Readings of the Standard Thermometer,) from April to December, of the
Year 1862.

The corrections 1°2 and -0°9 respectively have been applied to the readings from April
to July inclusive, to reduce to the standard thermometer.

RADCLIFFE OBSERVATIONS, 1862.

-

The corrections - 1°1 and -0°9 have been applied for August, and — 0°9 and — 0°8 for
September, to reduce to the standard thermometer,

The following corrections have been applied, to reduce to the standard thermometer:-

-0°9 and -0°7 for October.

-0°9 and -0°4 for November.

-0°9 and -0°6 for December.

The following Table gives the comparison of the Mean Monthly Temperature, from April to December, of the Air at the top of the Tower, (at an elevation of 105 feet,) and of the Air near the surface of the Ground, in the Year 1862.

The result of the comparison seems to shew that during the summer months the temperature at

the top of the tower is slightly lower than that near the surface of the ground, and slightly higher in the winter months.
