■2) The refult of Dr. Halley’s proportionals, (Lowtborp, 
Vol. III. p. 670.) filled up from year to year, to the 
1 ooth year. As thefe come fo near 1 174 (ftated p. 669. 
as the annual deaths), it fhould feem as if the firft at- 
tempt was made that way, to find how many of iuch 
deaths would tall in each ciecad. 
(1 b ) Exhibits the fame for 1000 births. 
( c ) By taking in the 238 that were fupprefied, flating the 
firft 6 years, according to the preliminary difcourfe, and 
continuing the account according to the table ; only 
letting back half a year, or poftponing 4 deaths to the 
2d decad, [and fo half the laft year’s deaths from every 
decad to the following] and this gives the 1238 intire. 
{d) Exhibits the laft preceding, computed for 1000 births, 
and as the table ought to be from thofe data, but yet 
ill proportioned. 
[e) Shews the decrements, or deaths, according to Dr. 
Halley’s table, beginning with 1000 perfons, and exhi- 
biting a fuppofed body of coexifting people, in all 
34,000. The firft decad, fo much below the truth, 
from 1000 births only, that it fwells the 9 decads fol- 
lowing with 122 deaths more than fhould be, as is re- 
prefented in (/). 
(g) The deaths of 1 700 perfons in the parifh of Ely Trinity. 
(h) The fame proportional for 1000 births. 
(/) and (k) The like for All-Saints in Northampton. 
.(/) The halves of the fums of (h) and (£) for ioco births. 
For, by comparing (d) and (e), you will fee, that the 
firft decad being lefs than it fhould be, (i. e.) fo much 
fhort of 469, throws back 122 deaths upon the other 
decads of life. And if this were 469, as it ought, it 
would fall between (b) and (k), Ely-Trinity and A IJ- 
Saints in Northampton. As this happens in the firft 
decad, I have joined both accounts, and halved them ; 
and the refult of it is ftated at (/); wh ch will be found 
as near (d) as can well be expected, in accounts of dif- 
ferent places *, and with this 1 fliall conclude this Poft- 
Tcript.
