^68 Dr. bland’s Midwifery Reports 
iiecelfary to premife fome account of the method I have fol- 
lowed. 
I have fuppofed each of the women to bear a child every two 
years ; this, from the account of thofe who returned to the 
Difpenfary a fecond, third, or fourth time, appearing to be the 
-mean term. Upon this principle, when 1 find that a woman 
applied at the Difpenfarj^ who had had one child before, I con- 
clude, that that child would be two years old, if living ; but 
if the woman had borne two children, I fuppole that the firft 
would be four, the fecond two years old, and fo on. And 
finding, that of 299 children borne by as many women, who 
were now advanced in their fecond pregnancy, 171, or feven- 
iweifths only were living, I conclude, that on an average 5 out 
of 12 die under two years of age: and obferving that of 508 
children borne by 254 women, who were now advanced in 
their third pregnancy, 259 only were living, I firft deduct 210, 
which is five-twelfths of the whole number, who died under 
two years of age ; and then find that 39, which is nearly one- 
twelfth of the whole number, or one-feventh of the furvivors, 
died between two and four years of age*
