(1) Persons of florid complexion retain this on the malar prominence for some time after death. (2) The red or livid edges of ulcers. (3) Blue, black, or red tattoo marks, if not effaced during life, do not disappear.--Ecchymoses retain the hue they had at the time of death. (4) An “icteric” coloration existing at death, as in jaundice, never becomes white. (5) A rosy tint of the skin on those poisoned by carbon monoxide. (6) Dusky-red patches in those frozen to death. (7) In certain cases of drowning, a rosy colour may be observed on the lips and malar prominences. 5. The _temperature of the body_ at the time of death is retained for some time. As a sign of death the fall of temperature must be progressively continuous. Cooling will depend on the medium in which the body is placed, and mere coldness of the body is not a sign of death. (1) Fat persons retain the heat longer than lean ones; adults longer than children or old persons. Bodies are cooled by--1. Radiation. 2. Conduction. 3. Convection. (2) Bodies immersed in water cool more rapidly than in air. This fact may be of importance in determining survivorship in a case of drowning. (3) Bodies in bed and covered by the clothes, or in cesspools and in dung-heaps, cool less rapidly than when exposed. (4) Persons killed by lightning may keep warm longer than others. (5) Death by suffocation retards the process of cooling. (6) The body may be cold externally, but possesses a considerable amount of heat when the internal organs are exposed. Persons who have died of cholera, yellow fever, or suddenly of some acute disease--rheumatism--may retain for some hours a considerable amount of heat. It has even been asserted that in some diseases--cholera--there is an increase of temperature soon after death (Laycock), also after death due to some diseases of the nervous system as in pontine hæmorrhage and cerebro-spinal meningitis, and following prolonged muscular spasm as in tetanus. (7) Most bodies, under ordinary circumstances, are, as a rule, quite cold in from eight to twelve hours after death. The rate of loss of temperature depends upon the difference between that of the body and its surroundings; it lessens as the body cools. It takes at least twenty-four hours for it to fall to the heat of the surrounding atmosphere. 6. _Relaxation, primary flaccidity, more or less general, of the muscular system takes place._ _“If the above signs are alone present, death must have taken place in from ten to twelve hours at the longest”_ (Casper). _Exception: cadaveric spasm._ 7. _Want of elasticity in the eyeball: flaccidity of the iris._ This condition invariably occurs in from twelve to eighteen hours after death.
