REPORT OF THE 
years above named; an approach to identity which points to 
the constancy of temperature spread over a considerable 
number of years. 
The annual range of temperatiu'e in the forty years was 
5° and eight-tenths, from a maximum of 50° and two-tenths in 
1834 to a minimum of 44° and four-tenths in 1855. The 
range in the 25 years above referred to was 6° and one-tenth. 
In the year just elapsed the temperature of January, “April, 
July, November, and December was above a mean. The 
remaining months were below: September 4°, and October 5°; 
the others to smaller amounts. 
The range of temperature in the year was 79 degrees from 
10'^ February 25, to 89 July 23. The range in the last 40 
years was from—3° and five-tenths in January 3,1854, to 87° and 
five-tenths in July, 1852, equal to 91 degrees. 
EAIN FALL. 
The Eain-fall of the year was only 19*79 inches, or 4.19 
inches below a mean of 40 years. The amount has been less 
only in three years during the forty aforenamed. The minimum 
of rain was 17*89 inches in 1850, and the maximum 38*56 
inches in 1872, more than double of the minimmn. 
It will be seen by the annexed table that in each of the 
returns, the rain-fall of 1873 was only about half the amount 
of 1872. From August to December the deficiency was con¬ 
siderable in each month, so it was also in April and June. 
>Snow fell in January on three days, amounting when melted to 
*68 inch; and four times in February, giving 1*13 inch. 
The mean rain-fall of the last ten years was 25*9 inches, or 
two inches more than the mean of 40 years. It is evident that 
mean quantities must be deduced from longer periods than a 
decade. 
In Professor Phillips’ Climate of York, he gives the rain-fall 
of periods between 1811 and 1850, as follows:—
