Iune. 26. 1672. Mr Hooke produced a new kind of speaking trumpet figured Bell wise repercussing
& by degrees Dilating it self, which being tryed & compared with that of Mr Coniers, was found to exceed it -
It was ordered that against the next Day, a pipe of the forme of an ordinary trumpet should be made widening

it /be/ discharged back into the air, and he wished that meanes might be used to Discouer whether there are not Values
in the arterys, by which the air may passe into all the parts of the Blood. For which purpose it was suggested
that an iniection might be made into those vessells, & particularly into some artery, with melted bees wax
mixed with tallow and coloured thereby to Make the vessells appear round and full, to see what might be fur-
ther discoured in their structure. This was Recomended to the Physitians of the Society. [a sheet of Cassinjs

Mr. Hooke affirmed that he had made a Refracting Obiect glasse vpon the same sphere with a Reflecting one
and found that it Represents the Object Brighter of the same charge and the same aperture with a Re-

of the Reflecting telescope of M Newton. Mr Hooke said that he had hitherto wanted a Mould of a sufficient
Bignesse for a speculum designed by him of 15 inches Diameter for a tube of 10 foot long But that he hoped
to haue in a week or fortnight such a mould cast wherein a Speculum of that bignesse might be well wrought

of 75 inches, & that the presidt. & Dr. Wallis had suggested diuer expts. determining the cause of that strange effect, it was in -
quired what had been done in this matter. mr Hooke answered that some tryalls had been made about it ^ /&/ that he would
bring in an account of them in Writing the next Day. [grew had describd some transverse sectios of plants [he was exhorted

with a Syphon in the open air they should be made both before the Society as soon as might be. Mr. Hooke
proposed a way of making the said Expts. with a Syphon in the open air by double pipes and by blowing
them both into one ball. he was desired to make vse of this contriuance. Mr. Hooke suggested that
It were worth trying whether air be consumed or be increased by Burning. He was desired to Divise
Some expts. for Determining his quere. Mr. Boyle suggested that it might be tryed to make air of
finer bodys than ordinary . Such as are Distilled liquors or chymicall salts in Distilled liquors, to find whether
such air will be more compresst by force than comon air. The same suggested also that It might be examined whether
in making salt peter by art there is any air intercepted & comprest.
