      "reasoning": "To investigate the luminous properties of meat, particularly veal, and determine whether the light is due to putrefaction, mechanical pressure, or other factors.",
      "description": "Observation of a neck of veal that exhibited luminous spots in the dark, despite its fresh appearance. The author tests various conditions (pressure, exposure to liquids, vacuum) to understand the nature of the light.",
      "quote": "After observing the neck of veal, which had been bought fresh, the author sent for it into a dark room and noted that it emitted light in various places. He then proceeded to examine the luminousness under different conditions, such as rubbing the meat, compressing it between glass, and exposing it to spirits of wine and water. He also tried to include the luminous part in a vacuum using a pneumatical engine to see if the light diminished.",
      "outcome": "The light persisted in water for over an hour and was only extinguished by high-proof alcohol. The vacuum experiment showed a gradual decrease in light intensity, suggesting the luminous matter was more tenacious than that of other glowing substances.",

      "reasoning": "To compare the luminous properties of different parts of the meat and other meats to isolate the cause of the phenomenon.",
      "description": "The author identified distinct luminous spots in the veal, including gristly parts of bones, the spinal medulla, tendons, and fleshy areas. He also tested a pullet (young hen) in the same larder to see if similar luminous properties were present in other meats.",
      "quote": "‘In this one piece of meat I reckoned distinctly above twenty several places that did all of them shine, though not all of them alike. ... The bigness of these Lucid parts was differing enough, some of them being as big as the nail of a mans middle finger, some few bigger, and most of them less. ... The parts that shone most were some gristly or soft parts of the bones, where the Butcher's Cleaver had passed; ... and lastly three or four spots in the fleshy parts at a good distance from the bones were plainly discovered by their own light.’",
      "outcome": "The luminous spots varied in size and intensity, with some parts (like bones) being more vivid. The pullet also exhibited luminous spots, though less vivid than those in the veal.",

      "reasoning": "To determine whether the luminous light is associated with heat or putrefaction.",
      "description": "The author tested whether the luminous parts of the meat were warm by applying a sealed thermoscope and noting the smell. He also observed the light’s persistence over time and its behavior under different environmental conditions.",
      "quote": "‘... I could not by the touch discern the least degree of Heat in the parts whence it proceeded; and having put some marks on one or two of the more shining places, that I might know them again when brought to the light, I applied a seal’d Weather glass, furnished with tincted spirit of wine, for a pretty while, and could not satisfy my self, that the shining parts did at all sensibly warm the liquor: ... Neither I, nor any of those that were about me, could perceive by the smell the least degree of stink, whence to infer any Putrefaction.’",
      "outcome": "No heat was detected, and no offensive smell was observed, suggesting the light was not due to putrefaction.",

      "quote": "‘I caused also a piece of shining flesh to be compressed betwixt two pieces of glass, to try, how well the contexture of it would resist that external force; but I did not find the light to be thereby extinguished during the short time I could allot to the Experiment.’",

      "quote": "‘But supposing, that high rectified Spirit of wine might so alter the contexture of the body it permeated, as to destroy its faculty of Shining, I put a luminous piece of Veal into a Crystalline phial, and pouring on it a little pure Spirit of wine that would have burned all away, after I had shaken them together, I laid by the glass, and in about a quarter of an hour or less I found that the light was vanished.’",

      "quote": "‘But water would not so easily quench our seeming fires; for having put one of them into a China Cup, and almost filled it with cold water, the light did not only appear, perhaps undiminished, through that Liquor, but above an hour after was vigorous enough not to be eclipsed by being looked upon at no great distance from a burning Candle, that was none of the smallest;’",

      "quote": "‘Whilst these things were doing, I caused the Pneumatical Engine to be prepared in a room without fire, (that the Experiment might be tryed in a greater degree of darkness;) and having conveyed one of the largest luminous pieces into a small Receiver, we caused the candles to be put out, and the pump to be plied in the dark; ... the diminution of light, after the pump seemed to have been employed for a competent while, appeared so inconsiderable, (whether because our eyes had leisure to be fitted to that dark place, or for what other cause soever,) that I began to suspect, that the instrument, having been managed in the dark, had leaked all the while. ... This tryal we once more repeated with a not unlike success;’",

The fourth day its light was also conspicuous, so that I was able in a dark Corner of the room to shew it even in the day time to three or four very ingenious Physitians, all of them (save one) members of the R. Society;’",
