By these tables we see (1) that the mean temperature of 1875 was a fraction of a degree lower than in 1874, westerly winds being markedly less prevalent, and that the mean temperature was lower and the warm winds less prevalent in the first, third, and fourth quarters of the year under review than in the corresponding quarters of 1874; (2) that the mean height of the barometer was a little higher in 1875 than in 1874, but lower during the first half of 1875 than the first half of the previous year ; (3) that as regards the rainfall of 1875 it was in excess of that of 1874 by more than three inches, though the excess was confined to the spring and summer quarters; and (4) that there was more cloud and more rain-time in 1875 than 1874. In 1875 the mean temperature was a little lower than the average, the mean barometer a little above the average, the rainfall decidedly in excess of the average fall. In the previous year the temperature, barometer readings, and amount of rainfall were all a little higher than usual.](https://iiif.wellcomecollection.org/image/b28926900_0014.jp2/full/800%2C/0/default.jpg)
