gamy level of arsenic have been found in Napoleon ’s hair , but that ’s not strange for the period . Many cosmetic , including hair’s-breadth tonic , contained arsenic . And there is no evidence of hemorrhaging of his heart and soul or other indicators of arsenic poisoning . Pathologists who have examine Napoleon ’s venter , however , see little doubt of the cause : the organic structure record clear signs of stomach Crab and a granulose substance find in the stomach bespeak GI bleeding , which most in all likelihood did Napoleon in .
