ty-two ; in Rome, one in twenty-three; in Amfterdam, 
one in twenty-four, &c. M. Sufmilch makes the pro- 
portion of thofe who die, annually, in great towns, to be 
from {, to ,',3 1n moderate towns, from ,', to 3 and, 
in the country, from:.*, to ,*,. But Dr.-Price fuppofes the 
following proportions more juft, viz. Great towns, from 
+7 OF =5) to “, or 7.3; moderate towns, from ;'.to {',; 
and the country, from 2 or ., to. or ,: and he is 
of opinion, with M. Sufmilch * that, taking a whole 
country in grofs, including all cities. and villages, man- 
kind enjoy among them about thirty-two or. thirty-three 
years, each, of exiftence; or,—which amounts to the 
fame thing,--that one out of thirty-two or thirty-three dies 
annually.—Sir William Petty, in his ¢ffays on political 
arithmetic, fays—that in the country, in England, one dies 
out of thirty-two; and, that five are born to four that die. 
“This laft fact, “faysM. Buffon,’ agrees pretty well with 
what happens in France: but if the firft fa&t be true, it 
follows, that the falubrity of the air in France is much 
greater than in England,—in the proportion of thitty-five 
to thirty-two ;—for, it iscertain, that, in the country in 
France, no more than one dies out of thirty-five.’—M, 
Sufmilch makes the proportion, as deduced from 1098 
country parifhes in Germany, to be one out of forty-three, 
He likewife givesthe proportion of one to forty-five for a 
country parith in Brandenburgh: and M. Muret eftablithes 
the fame, for the Pais de Vaud,--(See Dr. Price’s obferva- 
tions, é&c.) The two laft are the higheft propertions I find 
for any part of Europe. In Madeira, (an African 
ifland) Dr. Hicberden ftates.the proportion to be one in 
fifty—the climate of that Ifland, it is true, is remarkably 
jalubrious: but Dr. Price thinksthe eftimate of Dr. Heberden 
1s exceptionable. . Large towns give the proportions dying 
outof the whole number, much higher,—even at Brellaw— 
which has, inthis kind of calculations, been ftiled the
