                                The Barometrical heights at

By comparing these two Tables together, it is 
manifest, that the Mercurial Ascents are much great=
er at Petersburgh than at Lunden, and that the de=
scents are nearly the same. So that the Range of the 
Barometer at Petersburgh is 3 inches 31 hundredth parts,
but at Lunden only one inch & about 8 tenths.
Of the Winds & Weather at Lunden 
in 1724.
In January the Winds were, for the most part,
about the Westerly and Southerly points, & frequent-
ly very boisterous. The weather was some cloudy,
some fair, frequent rain, but no cold taken notice 
of till January 30.
In February the winds frequented the same
points as in January, but they lay more between the 
N & E than then, and they were very boisterous often=
times. In this month Snow was frequent, and now and 
then Thunder and but little fair weather.
