Note.—This table may be read thus: Of the 68 persons admitted to the before-mentioned institutions during the year 1844, 14 died previous to the middle of the year 1859, and 54 were surviving in that year. The average age on admission of the 68 persons was 13 9 years, and the average number of years elapsed between the time of admission and the middle of the year 1859 was about 15 years. According to the Massachusetts Life Table, the number that should be surviving in 1859 was 58 6, showing the number of actual survivors to have been 4"6 less than the number demanded by such table. The deficiency (4 6 + 5 3 + 2 6 12 5) of actual survivors relative to the number that should survive of those admitted during the three years 1844, 1845, and 1846, was, according to the Massachusetts Table, 8 9 per cent, of (58 6 + 37 3 + 44-6 ? 140 5) the number demanded; and the deficiency of actual survivors relative to the number that should survive of those admitted during the seven years 1839 to 1845 inclusive, was, according to the same life table, 8 7 per cent, of the number demanded. In like manner may be read the results derived from comparison with the English Life Table.

Note.—This table may be read tnus: Of the number of persons admitted to the above-mentioned institutions, between the ages i.f 10 and 14, the number that was surviving in 1859 was 8 6 per cent, less according to the Massachusetts Life Table, and 9 4 per cent. less according to the English Life Table, than the number that should then be surviving. Of the number of persons admitted during the three years 1838-40, from which the average time elapsing to the middle of 1859 was 20 years, the number that survived in 1859 was 12 3 per cent, less according to the Massachusetts Table, and 15*4 per cent, less according to the English Table, than the number that should then have been surviving. Of the number of persons admitted during the seven years 1839-45, from which the average time elapsing to the middle of 1859 was 16 6 years, the number that survived in 1859 was 87 per cent, less according to the Massachusetts Table, and ?? ? per cent, less according to the English Table, than the number that should then have been surviving.
