sire of the members present tooke the chair

The minutes of the Last Day were read & some amendments /were/ made about the
Relation concerning the wormes in the cauitys of the Os frontis, vpon wch. occasion
Dr. Croon added that he had obserued that the cauitys of the Os frontis and the
Little cells of the nose hauing in them a kind of gelly or slime are often filld
wth. wormes not only in sheep and other cattell, but, he had also obserud the
same thing in a humane Skull. but he conceiud that the said little wormes were
ingendred in the Mans head wch. he had anatomised after the Death of the person.
he hauing found them 7 or 8 days after the persons death. He was of opinion
also that the tickling of these kind of wormes vnder the horns of staggs was
the said cauitys extending vnder them was the cause of the staggs rubbing
oft his hornes. And Alledged Quelfer for the first author of the obseruam
Dr needham added that. the Gelly wch. countrymen take out of these cauitys in
such the heads of cattell troubled wth. the staggers &c was out of those caui
tys. -
vpon the mention of Dr. Plots way of preuenting smutty corne It was suggested
that it was only in the skill of choosing the seed before sowing and in
nothing els.

. . ., vpon the Discourse that was about the Instrument propounded
the last Day for the examining of the Differing pressure of the air of Diffe
ring heights aboue the superficies of the Earth mr. Hill suggested that it
were very desirable that a list of Enquirys and Experiments might be
made for that purpose
Dr Croone mentioned that mor. Paschall at Paris had vpon making this
Expt. found that there was fiue inches difference in the altitude of the -
mercuriall cylinders between the in the Barometer at the top & bottom
of the Hill mountaine on wch. it was tryed and that one inch of altitude
/in the all cylinder/ answerd to about 1000 foot of altitude in the atmosphere or air
mr. Hooke that this ^ /proportion of the two cylinders of & air/ made sometimes more sometimes lesse was not at
all times a like by reason that the specifique grauity of the air
did for many causes alter, as Did also the specifique grauity of the
mercury. but that by his Instuments which he was preparing fo
that Inequality would be Discouered

mr Hooke then produced two Experiments wch. he had promisd to Ex
hibit the Last Day. being those which were mentioned in the first.
