Table VIII exhibits, for every hour in the day, the Velocity of the Wind reduced to 4 and also to 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 3.2 corresponding to 19 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 names of Upper and Lower Clouds are given, but only one Direction, this refers to the Lower ouds. The prevailing Direction of the Wind at the Observatory, as shewn in Table VIII, was about by E; at the Peak, as shewn in Table IX about S; the Direction of the Lower Clouds was about
On an average 58 per cent of the sky was clouded.
Table XI and Table XII exhibit the readings of the Barometer reduced to 32.0 Fahrenheit but et 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 27.937. The Mean Temperature was 74.5 At the Peak and 81.3 at Cape d'Aguilar, the Highest was 82.9 on the 21st at the Peak and 92.3 on the ne day at Cape d'Aguilar, and the Lowest was 67.0 on the 15th at the Peak, and 74.8 on the 16th : Cape d'Aguilar.
The Mean Temperature in Hongkong decreased one degree Fahrenheit for every 238 feet ascended. Table XIII exhibits the Relative Humidity as determined from observations of the Dry and Damp. Bli Thermometers. The Mean Relative Humidity at the Observatory was 82, at Cape d'Aguilar
•. and at Victoria Peak 95. These numbers are reduced to the mean of the 24 hours by aid of Table IV. The Least Relative Humidity registered was 54 at the Observatory, 65 at Cape d'Aguilar,
171 at Victoria Peak, all occurring at 4 p. on the 21st.
Table XIV exhibits the Tension of Aqucous Vapour at the Observatory and at the Peak. The "Tension was 0.886 at the, Observatory, and 0.801 at the Peak. The Greatest Tension istered was 1.004 at 4 p. on the 12th at the Observatory, and 0.897 at 4 p. on the 20th at the Peak. The Least Tension was 0.768 at 4 p. on the 25th at the Observatory, and 0.696 at 10 p. on the 4th - the Peak.
Table XV exhibits the amount of Rain measured at 10 a. on the following day, and the duration Precipitation at the Observatory. The greatest amount fell on the 15th when it rained 2.500 at the
rvatory, 2.34 at Stone Cutters' Island, and 3.36 at the Peak.
