The meteorology of the year was as follows:—
| 1871. | Temperature, Average. | Difference from Average of 100 years- | Dew-point. | Humidity (Saturition=100.) | Height of Barometer. | Rain in inches. | Difference from average of 56 years. |
|---|---|---|---|---|---|---|---|
| Year | 48.7 | —0.1 | 42.7 | 81 | 29.79 | 22.5 | —2.7 |
| Winter Quarter (Jan. Feb. Mar. | 40.2 | +1.6 | 35.5 | 84 | 29.78 | 4.3 | —0.7 |
| Spring Quarter (April, May, June) | 51.5 | — 0.8 | 44.9 | 78 | 29.77 | 6.7 | +1.1 |
| Summer Quarter (July, Aug. Sept.) | 61.3 | +1.7 | 52.7 | 74 | 29.75 | 8.3 | +0.9 |
| Autumn Quarter (Oct. Nov, Dec.) | 41.8 | —1.9 | 37.8 | 86 | 29.84 | 3.2 | —4.0 |
Hence the mean temperature of the year was slightly below
the average; that of the winter and summer being above, and
that of the spring and autumn being below the average.
The rainfall during the year was somewhat below the average;
but not so much so, as in the previous year.
I have the honor to remain,
Gentlemen,
Your obedient Servant,
J. W. GRIFFITH, M.D.,
Member of the Royal College of Physicians.
November, 1872.
