successfully, it would be he.

"It was then the middle of the night. But Dr. Carrel was called on,
and when the situation was explained to him, and it was made clear
that the child would die anyhow, he readily consented to attempt
the operation, although expressing very slight hope of its
successful outcome.

"The father offered himself as the person whose blood should be
furnished to the child. It was impossible to give anaesthetics to
either of them. In a child of that age there is only one vein large
enough to be used, and that is in the back of the leg, and deep
seated. A prominent surgeon who was present exposed this vein. He
said afterward that there was no sign of life in the child, and
expressed the belief that the child had been, to all intents and
purposes, dead for ten minutes. In view of its condition he raised
the question whether it was worth while to proceed further with the
attempt. The father, however, insisted upon going on, and the
surgeon then exposed the radial artery in the surgeon's wrist, and
was obliged to dissect it back about six inches, in order to pull
it out far enough to make the connection with the child's vein.

"This part of the work the surgeon who did it afterward described
as the 'blacksmith part of the job.' He said that the child's vein
was about the size of a match and the consistency of wet cigarette
paper, and it seemed utterly impossible for anyone to successfully
unite these two vessels. Dr. Carrel, however, accomplished this
feat. And then occurred what the doctors who were present described
as one of the most dramatic incidents in the history of surgery.
The blood from the father's artery was released, and began to flow
into the child's body, amounting to about a pint. The first sign of
life was a little pink tinge at the top of one of the ears, then
the lips, which had become perfectly blue, began to change to red,
and then suddenly, as though the child had been taken from a hot
mustard bath, a pink glow broke out all over its body, and it began
to cry lustily. After about eight minutes the two were separated.
The child at that time was crying for food. It was fed, and from
that moment began to eat and sleep regularly, and made a complete
recovery.
