Mike Ware's "Strange Processes"

In Mike Ware's essay, Alternative Printing a Conspectus, he discusses obscure as well as traditional processes. His scholarship is apparent when he describes the most intriguing processes "recorded by C.M.Archer as an 'Anecdote History of Photography' in Recreative Science: a record and remembrancer of intellectual observation, Vols 1 and 2. (London: Groombridge and Sons, 1860/1)."

It has been concluded by doctors in America, that the last image formed on the retina of the eye of a dying person remains impressed upon it like the image on a photograph, and that if the last object seen by a murdered person was his murderer, the portrait drawn upon the eye would remain a fearful witness in death to detect him and lead to his conviction. Dr. Sandford, of New York, reports that he examined the eye of a murdered man at Auburn by means of the microscope, and found impressed on the retina the rude, worn away figure of a man, supposed to be the assassin!
