Asked Dr. Kimball about blood transfusions and the effect on white's of negro blood, if they would be considered to have "a drop of negro blood." Dr. Kimball said that the blood disintegrates within three weeks, and he would not have any left in that time; that even our own cells change rather rapidly, within 120 days.
