THE WEATHER.

AUGUST, 1866. A very fine "vrarm month — the mildest August by several degrees experienced in ths last nine years.- The mean temperature was equal to that of an English April. The spring, therefore, was well advanced at the end of the month, the artificial grasses being as far forward as in October last year. The thermometer once ro3e to 66 deg. in the Bhade, and on no occasion fell below 27 deg. A short gale from the westward occurred on the 28th. Snow fell on three days, but in very small quantities. The Aurora Australis was several times -risible. The Zodiacal Light was particularly bright on the 22nd. The mean temperature of the month was 473 deg,, which is 4*5 deg. above the average of nine years. The rainfall of the month was 4*477 inches, ■which is 0-3 inch less than the" average fall for the same period, The readings of the different instruments for the month are as follows : — Barometer (at 32 deg. and sea level)— Mean pressure, 29898 inches; maximum, 30 341, on 31st j minimum, 29-236, on 12th j range of atmospheric pressure, 1*125 inch. Thermometer— Adopted mean temperature, 478 deg. ; maximum, 660 deg., on 31st j minimum, JS7-1 deg., on 12th ; total range of temperature in moath. 38*9 deg. j mean daily range, 19 7 deg. Hygrometer — Mean degree of atmospheric humidity, -66 ; temperature of evaporation, 42.0 deg. : dew-point, 86.1 deg. ; tension of aqueous vapor, .212 inches. Amount of Evaporation — 2-036 inches Badiation — Solar maximum, 75 deg.; terrestenal minimum, 27*1 deg. Cloud — Mean amount, 5.7 ( 0-1.00). Wind — Mean force, 3.6 — (0.12). !* Anemometer — Mean diurnal movement of wind, 166 miles ; greatest, 308 miles ; greatest velocity, 57 miles per hour ; greatest pressure, 15 lbs. per foot on 28th. The following is a comparative table of temperature, weather, rain, and wind, in the month of August, during nine years : —

The Bluff report shows a considerable difference between the weatner on the coast and 30 miles inland — a difference greatly in tjvor of the latter. It ■will be obserred that the amount of cloud and force of wind are about the same at both stations, but rain fell at the Bluff on 18 days, and only 9 at Martendale.
