mr Hooke proposd an Expt. to see whether the blood doth circulate when the Lungs are subsided he was
disired to cause it to be made before the Society. the same mentiond that it had been obserued that blood
though of a dark blackish colour would when exposed in the air become presently very florid and
that florid surface being taken off and the subiacent part exposed againe would acquire the like flo
ridnesse, and that therefore it might be worth the observing by expt. whether the blood when from
the Right ventricle of the heart it passeth into the Left coming out of the Lungs, it hath not that
tincture of floridnesse before it enters into the Great artery, which if it should haue it would
be an argument that some mixture of air wth. the blood in the Lungs might giue that floridnesse
