38, OBSERVATIONS on THE 
full and fatisfactory of any I have yet feen, for Philadel 
phia, I think the births may be fairly ftated.as being dou- 
ble to the nnmber of deaths—At Salem in Maflachuietts, 
on a medium of the years 1782 and 1783, the births were 
to the deaths, as 109 births to 49 deaths, including the 
ftill-born in the number of deaths —Dr. Holyoke iays 
(in the memoirs of the American Academy of Arts and 
Sciences, Bofton,) that both 1782 and 1783. were fickly 
at Salem ;—particularly the latter years, in which, during 
the months of May and June, the meafles were epidemic. 
The births and deaths at Hingham, inthe fame ftate, dur- 
ing s4.years, gives to 100 births 49: deaths.——-Hence 
it may be inferred, that, fo far as deductions from thefe 
documents may be relied on, there are two births to one 
death, in this country. 
The peculiar circumftances of this mew country will 
not permit me to afcertain, from the deta ufually employ- 
ed for fuch purpofes, the comparative longevity of our in- 
habitants.—Agreeably to Dr. Halley’s table for Breflaw,* 
34 perfons, out of 1000, furvive 80 years cf age. In the 
paper on the longevity of the inhabitants of Ipfwich and 
Hingham, in Maflachufetts (communicated to the Bofton 
Academy, by the Rev. profeffor Wigglefworth,) the writ- 
er obferves, that, out of 164 perfons who died at Ipfwich 
Hamlet, in ten years, twenty-one perfons furvived eighty 
years complete; being one in about eight: whereas, at 
Breflaw, the proportion is one in about thirty—He alfo 
ftates, that, out of 1,113 deathsin 54 years, at Hingham, 
84 perfons furvived 80 years complete; being one in 134, 
It is obferved by Mr. Morfe, in his American Geography, 
that the flate of Conne@icut, though fubje@ to the extremes 
of heat and cold, in their feafons, and to frequent, fudden 
changes, is very healthful. He fays, that as manyas one in

® This docs not; however, by any means, correfpond with M. Buffon’s eftimate; as he 
makes the proportion to be only 27 63-100 out of 1000,—-
