once entertained of it, the record of the earlier experiments in connection with it has not the less interest. On November 11th, 1666, Pepys narrates: —
"Dr. Croone told me, that at the meeting at Gresham College to-night thure was a pretty experiment of the blood of one dog let out (till he died) into the body of another on one side, while all his own run out on the other side. 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."— Vol. iii., p. 85.
On November 16th the result of the experiment is given :—
"This noon I met with Mr. Hooke, and he tells me the dog which was filled with another dog's blood at the College the other day is very well and likely to be so as ever, and doubts not it being found of great use to men ; and so do Dr. Whistler, who dined with us at the tavern."— Vol. iii., p. 87.
What would Mr. John Bright or Archbishops Tait and Thomson say to Mr. Pepys' thoughtless witticism, which is eminently Palmer- stonian in its flavour ? The 'Philosophical Transactions,' in giving the details of the "experiment," slate that though "hitherto look'd upon to be of an almost (insurmountable difficulty, it hath been of late very successfully perform'd, not onely at Oxford by the directions of that expert anatomist, Dr. Lower, but also in London, by order of the R. Society, at their publick meeting in Gresham Colledge."
The Society soon grew bolder, for the following year found them extending the experiment of transfusion from dogs to mankind. Again let Mr. Pepys be the exponent. On November 21st, 1667, he went —
"With Creed to a tavern, where Dr. Wilkins and others ; and good discourse ; among the rest, of a man that is a little frantic, that is poor and a debauched man, that the College have hired for Ms. to have some of the blood of a sheep let into his body ; and it is to be done on Saturday next. They purpose to let in about 1-2 oz. ; which they compute is what will be let in in a minute's time by a watch." — Vol. iii., p. 416.
On November 30th we learn the result, so far, at least as concerns the man "that is a little frantic"; but how about the sheep? Pepys says —
