    Changes in Death-rate at Certain Periods of First Year, j We have seen that a reduction of 15 per cent in the infantile death- ite of Glasgow occurred during the fifty years under review, and in rder to discover the precise period of infant life wherein this fall ccurred, I have taken out the deaths in four groups of three years t the beginning of each decade since 1871. The deaths number in 11 37,914, and the births out of which they occurred 248,659, the eaths in each three-yearly period being assumed to have occurred ■om the births occurring in the three years ending at mid-year in re last year of each. GLASGOW.—BIRTHS AND INFANT DEATHS. Period. Births. Deaths. -3 months- -6 months. -12 months. Total. 1870-2. 57,549 4,135 1,799 3,863 9,797 1880-2. 57,762 3,774 1,443 3,329 8,546 1890—2... 60,296 4,195 1,541 3,258 8,994 1900-2. 73,052 5,239 1,868 3,470 10,577 248,659 17,343 6,651 13,920 37,914 I Stating the deaths occurring in these several quarters of the first ear as a proportion of the total births in each period, we have the blowing results :— DEATH-RATE AT -3, -6, & -12 MONTHS, PER 1000 BIRTHS. Period. -3 months. -6 months. -12 months. Total. y 1870-2 . 72 31 67 170 1880-2 . 65 25 58 148 1890—2 70 25 54 149 V 1900-2 . 72 26 47 145 Per cent reduction \ 1870-2, 1900-2 j — 16 30 15 So that the first result of the comparison is to show that a reduction f 15 per cent in the total infant mortality resolves itself into a con- nuous reduction of the rate, now amounting to 30 per cent during ie third and fourth quarters of the first year of life ; a permanence f the rate for the second quarter since 1880, although a reduction of 6 per cent when 1900-2 is compared with 1870-2 ; and an almost tationary character of the rate during the first three months of life.
