vpon this Dr. Grew alledged that he had formerly propounded a theory
of his own explicating the Pressure of the air by the Dissolution of salts
wherein his supposition was that the said salts before Dissolution weighd
more (that is augmentd the pressure of the air) and after Dissolution
Lesse, (that is Diminished the pressure of the air) this was not Debated
because he .. . . promised to bring in his theory as he had -
formerly Deliverd read it in this Society the next Day -
Whilst this was Discoursing mr. Wheeler propounded the last Day by mr.
Charles howard was put to the Ballot and was chosen by thesuffrage
of 30 wthout one negatiue -
Sr. Ionas more Related that mr. Townly had made obseruations of the
Barometer at townley for seuerall years & that the same alterations
had hapned that at the same time had been obserued at London

Also that he himself had obserued the same at Tangier for a whole
year and had not found the difference aboue of altitude more then
one inch all that time /in that place/, whence the ^/greater/ constancy of the weather of tht
place was argued, and that the same pressure of air was not the same in
all parts of the Earth but in some places always more some always Lesse
Sr. Christopher wren vpon the Discoursing of the varyings pressure of
the Sea and land winds, propounded the Bermudas as a very
conuenient place to haue tryalls made of the mutations of the
Barometer the seasons there being very temperate & the said
Island Lyeing in the incompassed on euery side wth. the sea and
very farr removed from any Land

mr Hooke related that he had been informed by Sr. Jonas more
that obseruations were now making in an other Island more
more conueniently situated for that purpose and namely in St
Helena on the other side of the line - .

This Sr. Ionas more confirmed and further added that the height of
the mercuriall Cylinder there had not exceeded 27 inches of altitude

The President Thought vpon the whole matter that it were very fitt
that Experiments of this obseruations of this kind should be made
in as many parts of the world as could be procured and that
all Experiments of that kind wheresoeuer made and by wtsoeuer
