Rigor Mortis and Algor Mortis |
 | | The result, in 1811, was the first scientific description of rigor mortis and "Nysten's law," which states: "The progress of cadaveric rigidity is descending." That is to say, it begins with the muscles of the face, then progresses to the neck, trunk, arms, and finally the lower limbs. |
 | | With this instrument, pathologists had been given the means to add hatch marks to the temperature standards of death known to the ancient Egyptians and Chinese. |
 | | Together, the triple stopwatches of rigor, livor, and algor gave nineteenth-century pathologists the confidence to estimate time of death over the first twenty-four to forty-eight hours, up to the point where lividity became fixed, bodies reached room temperature, and rigor melted away. |
