Dr. Carrel's dream of ten times the normal was exceeded by
himself."
Astounded as we were by this revelation, Kennedy did not seem to
consider it as important as one that he was now hastening to show
us. He took a few cubic centimetres of some culture which he had
been preparing, placed it in a tube, and poured in eight or ten
drops of sulphuric acid. He shook it.
"I have here a culture from some of the food that I found was
being or had been prepared for Mr. Pitts. It was in the icebox."
Then he took another tube. "This," he remarked, "is a one-to-one-
thousand solution of sodium nitrite."
He held it up carefully and poured three or four cubic centimetres
of it into the first tube so that it ran carefully down the side
in a manner such as to form a sharp line of contact between the
heavier culture with the acid and the lighter nitrite solution.
"You see," he said, "the reaction is very clear cut if you do it
this way. The ordinary method in the laboratory and the text-books
is crude and uncertain.
