Section 1. That Hereafter No Person Shall Make Upon Any Human Being

any scientific, medical or surgical experiment or operation, EXCEPT FOR THE BENEFIT OF THE PERSON EXPERIMENTED UPON, unless the intelligent, personal consent of such latter person shall previously have been obtained. Every such consent, to be valid, must be in writing and must be preceded by a full and correct written statement setting forth to the person whose consent is sought whatever painful, injurious or dangerous consequences are obviously liable to result from the proposed experimentation, and such statement shall be signed both by the experimenter and the person to be experimented upon.
