Toifes , which laft Number being divided by 63, the 
(Quote 56169 will be the Number of fquare Toifes con- 
tained in each Square, whofe fquare Root gives 237 
Toifes for the Side of each Square, which is juft if 
or 4 * of a Degree of a great Circle. 
Mr. de Life hath therefore by this Account made 
the faperficial Content of each Re ff angle, and confe- 
quentiy of the whole City of Taris too great by near 
one feventh. To confirm which beyond Contradidion 
we have Mr. de Life's own Teftimony, who in the 
Plan he himfelf has drawn and publifhed of Taris, and 
which he refers to in this very Account, has not made 
Squares of the above-mentioned Figures, but has given 
to their refpedive Sides the Proportion of 8 to 7, which 
is as near the true one as can well be exprefs’d by Lines, 
in a Plan of no larger a Scale than this. 
Now in the Account we have been confidering, Mr. 
de Life fays himfelf, that in his meafuring of London 
he drew Squares , whofe Sides contained 15 Seconds of 
a great Circle , and of thefe he fays, London contains. 
fxty. 
Therefore to compare Taris with London , we 
ought for the foregoing Reafons to make an Abatement 
out of the 63 Redangles which Tar is contain 0 , near- 
ly in the Proportion of 8 to y 5 but becaufe that is a lit- 
tle greater than the true one, let us make fuch Abate- 
ment only in the Proportion of 9 to 8, which is pretty 
confiderably lefs than the juft one. By which Abate- 
ment the Number of Squares, whofe Side is 15 Seconds 
of a great Circle contained in Taris , will be reduced 
from 63 to 56. And copfequently, acccording to Mr. 
de Life's own Way of meafuring, the Magnitude of 
London
