"The ducks of Mackinac Island are apparently not easily taken down. "Found a portion of the Lungs as large as a turkey's egg protruding through the external wound, lacerated and burnt, and below this another protrusion resembling a portion of the Stomach, what at first view I could not believe possible to be that organ in that situation with the subject surviving, but on closer examination I found it to be actually the Stomach, with a puncture in the protruding portion large enough to receive my forefinger, and through which a portion of his food that he had taken for breakfast had come out and lodged among his apparel." Thus reads Beaumont's somewhat windy account of the injury. Through that puncture--and in the slop of half-digested meat and bread suddenly visible in the folds of St. Martin's wool shirt--lay Beaumont's ticket to the spotlight of national renown. Italian digestion experimenters had pulled food in and out of live animal stomachs, soaked it up in sponges on strings, even regurgitated their own dinners, but St. Martin's portal presented an unprecedented opportunity to document the human juices and processes in vivo."
