A question and answer session on whether Lavoisier made an agreement with the French mathematician, Comte Joseph-Louis Lagrange shortly before being beheaded that he would blink his eyes if he retained consciousness after being beheaded and that he was executed because of his revolutionary scientific views is described. The circumstances surrounding Lavoisier's death and burial also cast doubt on the authenticity of the so-called death mask of Lavoisier, which the Fisher Scientific Company once claimed to have owned.
