At the other periods specified there are less male than female deaths; the difference after the age of 60 continu- ally increasing, until 90 to 100, when it was as 27.18 to 72.82 per cent. By table II it appears that there were a greater number of males than females at any age among the living population. A comparison of these with the deaths will show that at certain ages a greater proportional mortality prevails among- males, and at other ages among females. Mortality of the Different Seasons of the Year.—In table VIII we have arranged the deaths in each period according to the months in which they occurred, distinguishing the males from the females, and placing before the numbers the sign minus, when it was less, and the sign plus, when it was greater than the mean. In the third column we have given the proportion, which the total of each month bears to 12000, or 1000 per month, and in the fourth column, the number, indicating the order of the month in regard to mortality—the highest being numbered 1. It appears from this statement, that the months of August, September, and October, have the highest mor- tality. December is number 4 in each period; November 5 in the last, and 6 in the others. June has uniformly the least mortality. If the proportions are arranged according to the seasons of the year, they will be as follows: 1811-1820. 1821-1830. 1831-1839 Winter, 2.801 2.775 3.000 Spring, 2.842 2.825 2.622 Summer, 2.807 2.996 2.800 Autumn, 3.550 4.434 4.578 12,000 12,000 12,000
