(mr. Boyles letter about the monster. 2 of a dissection where there was but one kidney -)
An account was by mr. Hooke brought in about an expt of Refraction made wth pure & cleer salet
oyle, which was found to haue a much greater Refraction then any liquor he had yet tryed the angle
of Refraction that answerd to an angle of Inclination of 30 degrees being found noe lesse than
46o. 30'. and the angle of refraction that answerd to an angle of inclination of 20 degrees
being 29o. 47'. orderd that this Expt. be made before the Society at their next meeting.
and that the Instruments be fixt as also that other liquors as seuerall wines. aquafortis
aqua Regis, milk &c be tryed and that in seuerall temperaments of Heat and cold
mr. Hooke acquainted the company in writing wth. the successe of an expt. made vpon a dog
cutt open aliue and kept soe for aboue a whole howre by meanes of a pair of Bellows &
a pipe thrust into the wind pipe of the dogg whereby the windpipe being blown the heart
continued beating for a long while after all the thorax and belly had been displayed &
the diaphragme in great part cut away. Orderd that this account be entred and that the
physitions of the society doe consider against the next meeting whether and how this expt
may be further Improued It being said that air was felt to passe through the Lungs.
Dr Godderd conceiued that it might doe soe vpon a stretch and by more than ordinary force
but if it should doe soe vpon an animal vnopend & passe in a considerable quantity into
his brest, and Lodge there between it and the Lungs it might be a prejudice and hinde
rance to the motion of the Lungs. (of Starr shoot:) Dr. Pope that there was a book lately pub
lished in Italy conteining 800 sort of funguses. Q O. Dr. merret said there was 100 sorts of them
here in England). mr. Palmer produced a very heauy minerall stone conceiud to be Tin

mention being made again of the Expt. vpon the a dog cut open aliue and kept Soe

ported that the minerall stone supposed to be a tin stone produced by mr. Palmer
at the precedent meeting being weighed in water was found to be 6 1/2 times as
heauy as water. (Mor. Zulichems expt of simple penduls being Isocrone to triangles
and other figures and bodys diuersly suspended were begun to be made verifying
what he had written that a triangle Rectangle and Isoscheles being suspended by
the top or by the middle of its Base and agitated on the side is Isocrone to the sim
ple pendul of its perpendicullar altitude. (mr Howard fat of a man) There were
read two or three Expts. of Refraction vizt with cold & hott and salt water where
the Hot and Cold were Refracted alike. their angle of Inclination being 30o. tht
of Refraction was 42o. fere. But the salt water at the same angle of Inclina
tion had an angle of Refraction of 44o. by which it seems that salt increaseth
the Refraction. Orderd that water should be farther tryd with Seuerall degrees
of saltnesse to see whether by the Degrees of Refraction the Degree or quantity
of Salt might be Discouered, as also wth seuerall sorts of Salt fixed and volatill
Especially to obserue whether volatill salts Dissolued in water would Increase the
Refraction. It was hinted that by the Expt. of Refraction hitherto made it seemd
that the simplest Liquors haue the Least Refraction and on the contrary that li=
quors consisting of Differing parts suffer greater Refractions. Dr. Godderd pro
posed that tryall might be made of turbid & Coloured waters, others proposd oyle of
vitriol spit of Niter Aqu: Regis. Aq: Fortis Item to let the Ray passe out of air into
water, and out of that other kinds of Liquor and out of them into glasse to see
how the Refractions thus orderd doe Differ. Sr Rob: moray inquired whether
a contriuance might not be made to obserue the Refractions of steames and smokes
the same suggested that the Refractions of one and the same Liquor might be tryed
at seuerall Inclinations. mr. Hook proposed to find the Difference of the Refrac
tions of air and the vacuity of air in a glasse, the same was orderd to bring in
a List of Expts of Refractions at the next meeting - Expt. for next Day. Refractions of
