METEOROLOGICAL OBSERVATIONS FOR DECEMBER, 1871.

ATMOSPnEBic Pbessube. — The barometric column for December has been comparatively steady, the mean for the month being 30.10 inches. Highest readings occurred on the 18th 19th, 30th, 31st. The maximum for the month was on the 31st, when the height of the column read 30.39 inches. Tho mini* mum for the month occurred on the evening of the 9th, when it read 29.80 inches. With this exception, the daily range has been 4.5, ' but on the above date the range was 28. Tempebatube OB THE Aib.—The maximum temperature for the month was 73.38, and the minimum 55.45, with the exception of the 20th, when the maximum for the day was 81 °. The temperature, like the barometer, has been pretty steady, though the average rauge, 18°, was perhaps greater than past months. The greatest daily range was on the 15th—range on that day being 24 °. Mean temperature of solar radiator thermometer (black bulb in vac) was 142 ° . Rbi-ative Humidity.—The past month was remarkably dry, mean humidity being 673, complete saturation being 1.000. The days when the aqueous vapour was smallest were 2nd, 4th, 10th, 17th, and only on the * 27th did it'approach anything near saturation. Daily average of a cubic foot of vapour, 5.257 | grains, ft Rain. —Rain fell on nine days. 'On the I 12th 0.01 fell, the smallest quantity for the ■ month.' On the 27th, 0.64, the greatest for ■ the month. Totnl being 1.31 inches. I Wind.—-The" quantity for the month has c been much less than past months,. the total 1 number of miles blown over being 8,016, at I *n average daily rate of J?58.5 miles. The

largest -mount registered was on the 30th,and fop smallest on the 31st. During the past tour months the amount of wind blown over from the various paints is as follows :— From N., 3,339 miles From S., 12,763 miles From W., 12,152 miles Making a total of 27,254. These quantities have been calculated from forces which have been parallel, and will serve as a triangle, from which may be computed the point of the compass, from which a constant wind for this period has been waving.
