[In margin]92   Feb. 4. Dr Kings Discoure. Vpon occasion Giuen by this Discourse concerning muscular motion. Mr Hooke Declared to the Company that he had made some Discouery of the structure of a muscle by inspection with
a microscope. Dr. Grew supposing that that Discouery might be the same with what he had formerly Disco
uered acquainted the Society that he had some time since discouered that the fleshy part of a muscle was di-
uided into a sort of long parallelypipeds by the crosse interweauings of small membranes and vessells crossing
the said fleshy part. Dr croon supposed those fleshy parallelipeds, of a chaine of Bladders.
which being blown vp by certain Liquors did shorten the said strings & so contracted the muscle But mr
Hooke said that he could not discover any such texture in the said fleshy part, but that his observation was
that the fleshy part of a muscule consisted of an infinite number of Exceeding small Round pipes, extended
between the two tendons of the Muscles and seemd to end in them. which tendons in the muscles of Beefe
boyled would be easily stripped off from the ends of those pipes, and soe Leaue the ends of the round pipes very
distinct. He said that the reason of the moving of a muscle might be from the filling or emptying of those pipes
whose sides seemd to be flexible like those of a gutt. they were all desired to make out their Respectiue
notions about the Fabrick of muscles by ocular demonstration.
[In margin]94   Feb: 11. Dr. Crone of Flying. -- Mr. Hooke contuinued that than was a way which he knew to produce strength soe
as to giue to one man the strength of 10 or 20 men or more, and so contrives muscles for him of an aequivalent -
strength to those in Birds. The same hinted also that a contrivance might be made of something more proper for the
feet of men to tread the air, than for his armes to beat the air. [Sr W Petty mentiond that perhaps it might proue of use
to consider, whether Gunpowder being of soe great & quick a force might not be slackned to giue a slower motion as on a
mortarpeice the shell is much more slowly carryed through the air than a bullet out of a musquett. Some said it would
be of reall vse to contriue something for flying, if it were but to Rayse a man soe high as to fly ouer a Wall & the beseigers of a
town, to carry & bring back intelligence. [Bullield obs of Eclip Ian 1. 75.-
