    1. Deficiency of blood due to hemorrhage. 2. Effect of certain diseases and poisons. Post-mortem Signs.—The cavities of the heart contain a normal quantity of blood. The blood is simply arrested in its course ; blood is therefore found in the large veins and in the arteries. The brain and the lungs are not engorged with blood. Asphyxia, from d priv. et a-<£u|is, pulse. Apnoea is the better term—d priv. et ttvcco, I respire.

Certain diseases affecting the lungs— pneumonia, bronchitis, etc. etc. 2. Mechanical obstruction to respiration—strangula- tion, drowning, hanging, etc. Post-mortem Signs.—Engorgement of the pulmonary artery, the right cavities of the heart, and vena, cam, is present; but on the left side of the heart, the cavities, together with the aorta, are either empty or contain but little blood. It must be remembered, however, that cases of asphyxia do sometimes occur where the cavities on each side of the heart are empty, or nearly so. If also the obstruction to respiration be imperfect, the circulation may be continued for some time, con- gestion of one or more of the internal organs being the result. Coma.—Death in this case is due to some cerebral mischief. Came .—Apoplexy, fracture of the cranial bones, compression or destruction of the brain substance. Post-mortem Signs.—Congestion of the membranes and substance of the brain, and of the lungs. The cavities of the heart, especially those of the right, con- tain more or less blood.
