Note 12 — Chapter 30

"A very decided luminosity has been observed to proceed from dissecting-room subjects, the light thus evolved being sufficient to render the forms of the parts (which are peculiarly bright), almost as distinct as in the daylight.... Three cases are recorded by Sir H. Marsh, in which an evolution of light took place from the living body.... The light in each case is described as playing around the face, but not as directly proceeding from the surface; and in one of these instances, which was recorded by Dr. D. Donovan, not only was the luminous appearance perceptible over the head of the patient's bed, but luminous vapours passed in streams through the apartment."—Dr. Carpenter.
