Page[922] experimented on three kittens, suffocating them in cinders. The post-mortem examinations showed the veins engorged, left side of heart empty, right side full of dark, half-clotted blood. Lungs distended, much congested, color violet; many small fluid hemorrhages in substance; no subpleural ecchymoses. Frothy mucus tinged with blood in trachea and bronchi; bronchi congested. Brain and abdominal organs normal.

Proof of Death by Suffocation.

It is sometimes difficult in a given case to state WHETHER DEATH IS DUE TO SUFFOCATION. There is no lesion which of itself could be accepted as proof. But a collation of the lesions found taken in connection with the surroundings of the body will in many if not in most cases lead to a definite conclusion.

Infants have been found alive four and five hours after having been buried in the earth.[923] If the pulverulent material has penetrated into the œsophagus and stomach, the burial has occurred during life. Exceptionally when burial has occurred after death and traces of the material are found in the air-passages, they are not found in the œsophagus or stomach.

The committee on “Suffocation,” of the New York Med. Leg. Soc., reported[924] the following group of appearances as evidences of death by suffocation: The general venous character of the blood, the turgidity of the larger veins, the congestion of the parenchymatous organs, especially at the base of the brain, the lungs congested in a variable degree and œdematous, frothy mucus in the bronchi, the right side of the heart always fuller than the left. Fitz[925] holds that suffocation is a condition composed of a group of symptoms and appearances due most probably to accumulation of carbon dioxide in the blood and a deficiency of oxygen. The appearances are: The blood dark and fluid (though in gradual suffocation there may be clots in the right side of the heart), the right side of the heart full, venous congestion of the lungs (not constant), interstitial emphysema of the lungs, and venous congestion of the liver, kidneys, and brain. He prefers the word engorgement to congestion in this connection.

Tardieu[926] holds that when in infants buried in pulverulent substances we find emphysema of the lungs in high degree, bloody froth in the air-passages, abundant subpleural and subpericardial ecchymoses and the blood fluid, the burial has occurred during life. The same lesions are found in small animals similarly treated.

It must not be forgotten that an intoxicated person or one in an epileptic spasm is practically helpless, and can, therefore, be suffocated, accidentally or otherwise, under circumstances in which one in possession of his senses would be able to escape.

Accidental, Homicidal, and Suicidal Suffocation.

Accidental suffocation is frequent, as has already appeared. Suicidal suffocation is very rare. Homicidal suffocation occurs. Foreign bodies have been forced into the air-passages. Smothering has been done by holding the face in various materials to prevent access of air; by pressure on the chest; by forcible closure of the mouth and nose as in burking; by laying compresses over the face, as in the case of King Benhadad,[927] whom Hazael killed. “And it came to pass on the morrow that he took a thick cloth and dipped it in water, and spread it over his face so that he died; and Hazael reigned in his stead.” Benhadad was already quite ill and not expected to live.

Death by suffocation[928] may be considered as presumptive of homicide unless the facts are already referable to accident.
