106 REV. C. W. HARVEY-METEOROLOGICAL OBSERVATIONS 
Pressure. —The mean for the year was exactly the mean for the 
four-year period. The range of mean pressure has been from 29-96 
ins. in 1880 to 29*91 in 1882 ; the absolute range of pressure being 
from 30*94 ins. on 18th Jan. 1882, to 28*83 on 18th Nov. 1880, 
or a total range of 2*11 ins. In the present year the mercury 
attained its highest point, 30*70 ins., on March 4th, and its lowest, 
28*86, on Sept. 2nd, giving a range of 1*84 in. The other dates of 
high pressure, when it exceeded 30*50 ins., were April 6th and 
Dec. 25th; and of low pressure, when it was below 29*00 ins., 
Peb. 2nd and Nov. 6th. 
Temperature. — The mean for the year was as nearly as possible 
the mean for the four-year period. The range of mean temperature 
has been from 47°*8 in 1883 to 46°*2 in 1881. The absolute 
range for the whole period is the absolute range for 1881, i.e. 
89°*6 on July 15th to 10°*7 on Jan. 22nd, or a range of 78°*9. 
The range, for the year was 62°*4. The excess in temperature was 
most noticeable in January and October, whilst the deficiency was 
most noticeable in March and July. The middle of winter and of 
autumn thus were warm, whilst the early spring and the middle of 
summer were in the one case very cold, and in the other somewhat 
cold. The first three days of January were exceedingly warm.

On the other hand, some of the minima of March were remarkably 
low for the season, and were the minima of mid-winter rather than 
early spring.

It may be remarked that while the mean temp, of March 25th, or 
Lady Day, was as low as 34°*2, the mean temp, of Christmas Day 
was as high as 40°*7, a difference of 6°*5. As a matter of curiosity 
I give the readings for these two days.

Late cold was thus followed by early heat, and the max. of May 
exceeded that of July. It is not often, I fancy, that in two months, 
i.e. March 24th to May 24th, it is possible to show a range of 60°.
