Q. Well now, you have, first of all, a basic requirement for experimentation on human beings, “(1) the voluntary consent of the individual upon whom the experiment is to be performed must be obtained.”

A. Yes.

Q. “(2) The danger of each experiment must be previously investigated by animal experimentation,” and “(3) the experiment must be performed under proper medical protection and management.”

Now, does that purport to be the principles upon which all physicians and scientists guide themselves before they resort to medical experimentation on human beings in the United States?

A. Yes. They represent the basic principles approved by the American Medical Association for the use of human beings as subjects in medical experiments.

Judge Sebring: How do the principles which you have just enunciated comport with the principles of the medical profession over the civilized world generally?

A. They are identical, according to my information. It was with that idea in mind that I cited the principles which were mentioned in this circular letter from the Reich Minister of the Interior dated 28 February 1931 to indicate that the ethical principles for the use of human beings as subjects in medical experiments in Germany in 1931 were similar to those which I have enunciated and which have been approved by the House of Delegates of the American Medical Association.

Mr. Hardy: Is it possible that in some field of scientific research investigation by animal experimentation would be inadequate?

A. Will you repeat that question? I did not get it.

Q. Is it possible in some fields of medical research that experimentation or investigation on animals would be inadequate?
