The year 1863 closed with very fine weather for the season all over 
the country, which had continued for several weeks. At the 
beginning of January 18G4 the weather changed, and till the 9th it 
was exceedingly cold, averaging a daily deficiency of 8i°. On the 
10th a period of warm, damp, and foggy weather set in, and till 
February 3 there was an average daily excess of 3^° of temperature. 
On February 4 a cold period set in, lasting till the 11th ; five days 
warm weather followed, ending the 16th ; the daily excess, 61° 
nearly. From February 17th the weather was altogether wintry, 
and the average daily deficiency for 16 days, ending March 3, 
was 4i° From March 4 to 15 the weather was warm, with an 
excess of 2|° daily; from March 16 to the end of the quarter the 
deficiency was 2°. During the quarter there was an unusual 
number of alternations in temperature. 
The mean high day temperature was below the average to the 
amount of 1°'9, 3 0- 6, and 0 o- 4 respectively in these three months. 
The mean low night temperature was below the r average to the 
amount of l° - 9, 2°-4, and l°-3 respectively. Therefore both the 
days and nights were cold in these three months.

below the averages of the preceding 23 years. 
The degree of humidity was less than its average in January and 
February, and a little above in March. 
The pressure of the atmosphere was a little more than i in. in excess 
in January, somewhat in defect in February, and about I in. in March. 
The fall of rain was in defect in January and February to the 
amount of 0*9 in. and 0-8 in. respectively, and in excess to the 
amount of l - 2 in. in March.
