If fume miftakes, and unfair comparifons, a rile 
from divers tables not beginning all from the fame 
point ; if in the London accounts the abortive and 
fbilborn muft be thrown out, and alfo an allowance 
made for as many as die in the greater part of the 
firft year (while the i238 Bre{lau births were re- 
ducing to iooo perfons only), before a juft compa- 
rifon can be made with Dr. Halley’s table, as it now 
/lands ; then the 8 1 1 o at London ( 1 1 ) muft be re- 
duced, or elfe the 202, or rather the 342 above- 
mentioned, be further increafed by an allowance for 
fuch abortive and ftilborn. And when thefe altera- 
tions are made, the accounts of the two places will 
not appear fo amazingly different, in proportion to 
their refpeeftive numbers, upon the whole. 
Befide the inconvenience of the various accounts 
not beginning together, I /hall add another objection 
no lefs material ; that the tables are formed in too 
fmall numbers, and, by that means, cut off 20 or 
30 years of the term of life, and undervalue it in 
annuities, as nothing worth. He that begins with 
1000 only, either flops flioit of 90, or runs quite 
out between the 95th and 100th year, and can go 
no further ; becaufe out of 1000 births, it is not ex- 
pected, fo much as one fhould arrive at the age of 
100 years. But what muft become of thofe many 
(ij) Adding 2000 to the burials divided by io, is, in effect,, 
adding 20,000 to the whole. The increafed column is 5 fhort, 
which would arife from additional parts loft, and make the full 
fum. The laft number in the Brcilau column ftiould not be 33, 
but 27. Dr. Brakenridge.
