Table VIII exhibits, for every hour in the day, the Velocity of the Wind reduced to 4 and also to 2 Directions, as well as the Mean Direction of the Wind, which exhibits a great daily variation.
Table IX exhibits the Direction (to two points) and Force of the Wind (0-12) at Victoria Peak. The Average Force of the Wind was 3.5 corresponding to 20 miles an hour. The Sea Disturbance (0-9) exhibited in the same table has been derived from observations made at Cape d'Aguilar.
Table X exhibits the Amount (0-10), Name and Direction, whence coming, of the Clouds. Where the names of Upper and Lower Clouds are given, but only one Direction, this refers to the Lower Clouds. On an average 43 per cent of the sky was clouded. There were more Clouds during the day than during the night.
Table XI and XII exhibit the readings of the Barometer reduced to 32.0 Fahrenheit but not to Sea Level, at Victoria Peak, and the Thermometers at Victoria Peak and at Cape d'Aguilar.
The Mean Height of the Barometer at the Peak was 27.993. The Mean Temperature was 74.0 at the Peak and 80.4 at Cape d'Aguilar, the Highest was 82.5 on the 8th at the Peak and 91.0 on the 20th at Cape d'Aguilar, and the Lowest was 67.0 on the 24th at the Peak, and 73.6 on the 8th at Cape d'Aguilar.
The Mean Temperature in Hongkong decreased one degree Fahrenheit for every 252 feet ascended. Table XIII exhibits the Relative Humidity as determined from observations of the Dry and Damp Thermometers. The Mean Relative Humidity at the Observatory was 76, at Cape d'Aguilar 82, and at Victoria Peak 87. The Least Relative Humidity registered was 44 at 4 p. on the 20th at the Observatory, 52 at 4 p. on the 22nd at Cape d'Aguilar, and 64 at 10 a. on the 22nd at Victoria Peak.
Table XIV exhibits the Tension of Aqueous Vapour at the Observatory and at the Peak. The Mean Tension was 0.811 at the Observatory, and 0.741 at the Peak. The Greatest Tension registered was 0.967 at 4 p. on the 14th at the Observatory, and 0.920 at 4 p. on the 7th at the Peak. The Least Tension was 0.518 at 10 a. on the 23rd at the Observatory, and 0.538 at 10 a. on the 22nd at the Peak.
Table XV exhibits the amount of Precipitation at the Observatory. Observatory, and 6.50 at the Peak. Cutters' Island.
