[William Croune, or Croone, of Emanuel College, Cambridge, chosen Rhetoric Professor at Gresham College, 1659, F.R.S. and M.D.  Died October 12th, 1684, and was interred at St. Mildred’s in the Poultry.  He was a prominent Fellow of the Royal Society and first Registrar.  In accordance with his wishes his widow (who married Sir Edwin Sadleir, Bart.) left by will one-fifth of the clear rent of the King’s Head tavern in or near Old Fish Street, at the corner of Lambeth Hill, to the Royal Society for the support of a lecture and illustrative experiments for the advancement of natural knowledge on local motion.  The Croonian lecture is still delivered before the Royal Society.]

and by and by to an exceeding pretty supper, excellent discourse of all sorts, and indeed [they] are a set of the finest gentlemen that ever I met withal in my life.  Here Dr. Croone told me, that, at the meeting at Gresham College to-night, which, it seems, they now have every Wednesday again, there was a pretty experiment of the blood of one dogg let out, till he died, into the body of another on one side, while all his own run out on the other side.

[At the meeting on November 14th, “the experiment of transfusing the blood of one dog into another was made before the Society by Mr. King and Mr. Thomas Coxe upon a little mastiff and a spaniel with very good success, the former bleeding to death, and the latter receiving the blood of the other, and emitting so much of his own, as to make him capable of receiving that of the other.”  On November 21st the spaniel “was produced and found very well” (Birch’s “History of the Royal Society,” vol. ii., pp. 123, 125).  The experiment of transfusion of blood, which occupied much of the attention of the Royal Society in its early days, was revived within the last few years.]

The first died upon the place, and the other very well, and likely to do well.  This did give occasion to many pretty wishes, as of the blood of a Quaker to be let into an Archbishop, and such like; but, as Dr. Croone says, may, if it takes, be of mighty use to man’s health, for the amending of bad blood by borrowing from a better body.  After supper, James Houblon and another brother took me aside and to talk of some businesses of their owne, where I am to serve them, and will, and then to talk of publique matters, and I do find that they and all merchants else do give over trade and the nation for lost, nothing being done with care or foresight, no convoys granted, nor any thing done to satisfaction; but do think that the Dutch and French will master us the next yeare, do what we can:  and so do I, unless necessity makes the King to mind his business, which might yet save all.  Here we sat talking till past one in the morning, and then home, where my people sat up for me, my wife and all, and so to bed.
