or, say, - 
= 0-409 per thousand per year, 
of a man per thousand per year ; which works out to 4*1 4 
persons per thousand in ten years, or would show that only 8-28 
more have been born than have died in every ten years — a figure 
that need only be mentioned to be scouted by every thoughtful 
mind. On the other hand, taking the interval from the Deluge to 
be what Ussher’s chronology makes it (only with the addition of 
three years, so as to place Christ’s birth in the year of the Egyptian 
census 8 B.C.) we have 
4,000- 1,656 = 2,344 years from the Deluge to the Birth of 
Christ, 
7 years thence to the usual beginning of the 
Christian Era, 
1,900 years thence to the last general census, 
4,251 years in all. 
So, letting 1 stand as before for the average fractional increase 
x 
per year, and having 8 persons instead of 2 as the number at our 
starting point, we get the equation —
