the Solution of the Lasted too long to make an end of the expt. at this meeting, the Issue of it was Referred to
The Curator proposed an expt. to try in an instrument for compressing air how much longer a bird would liue in the compressed air of
a glasse than in the ordinary air of it accordingly a bird was put into the glasse with ordinary air at 6 minutes past 5 a clock & taken
out at 30' when it began to be sick being taken out & recouered it was put in againe at 40' & 3/4 of the air was compresst
vpon it in the space of 11 minutes by the gage. the bird was kept in this condensed air for 33'. and seemd to
be very well but the Instrument not being stanch it was ordered the expt. should be repeated at the next
meeting. soe as to prouide diuers glasses of seuerall dimensions and some birds of the same kind to see
if there would be an aequall proportion between the time of the birds life & the quantity of the air
in the glasses. The curator affirmd that an expt had been formerly made by order of the Society as
would appear by their Iournall where a burning Lamp Lasted much Longer in compressed than vncom
pressed air the amanuensis was orderd to find out that note against the next meeting. (Rights Letter

Iuly. 16. 1668. stenos Expt. tryd by Dr King) The curator produced a new kind of Leuell diused by himself
with a peice of glasse bent into a curue hauing this aduantage aboue other Leuells that it is of a
true figure other Leuells made wth glasse canes not being soe. but because the bubble water & bubble
of air in the water is subiect to Rarefaction & Condensation it was thought necessary that an other
liquor should be imployd that is not soe, it was orderd that one of those Leuells should be made
for the Repository and a description thereof brought in for the register. (wallis's paper commendation

The curator produced some petrifyd bodys vitrolated which he affirmd were the teeth of sharks. the
same affirmd to haue found many shells in portland stones, and at this time it might be seen
in such stones lying about the Exchange, others as Dr Ball & mr. Skippon took notice of shells plentiful
to be found at the tops of hill particularly on the Appenines and here also in England which was con
ceiud by some could not be solued but by earthquakes though others thought it might be by the
Deluge. The Curator vpon occasion intimated that he thought Alcalys being Exposd to the air
would arrest the Volatill salt that is in the air and turne it into niter. mr Cox added to the
consideration of the Company whether the air added that nitrous substances to Alcalys or Extrica
ted it out of them. It was conceiued this might be best decided by weight e.g. to weigh a quantity
of salt of tartar before exposd to the air & after. mr. Cox said he had a way of fermenting vegetable
wthout additamt. that being distilld they shall yeald in the form of a Volatill salt, which if the herbs were burnt
would be an Alcali. -
Iuly 23. 1668. The Curator produced seuerall petrifyd teeth sayd to haue found in sheernesse
and there taken out of a rock on the seaside. conceiud to haue been the teeth of shark fishes. mr Skippon
produced the like teeth & seuerall other stones & medicated earths, brought by him out of malta.

Iuly. 30. The expt. of shutting vp two finches of in two glasses of differing sise was tryd. the vessells wer
closed wth good cement. one conteining 4 1/2 times the quantity of the other. the birds were put in at

the other was kept 1h. 28'. and appearing to be sick though not very sick was taken out it being tim
for the company to rise. whereby it seems that the times and the quantity of air necessary for Respi
