63. In order to examine properly the state of the lungs, heart, and great vessels, with a view to determine whether or not the child had breathed, the inspection should be made in the following order: Attend, first, to the situation of the lungs; how far they rise along the sides of the heart; to their colour and texture; whether they crepitate or not. Then secure a ligature round the great vessels at the root of the neck, and another round the vena cava above the diaphragm. Cut both sets of vessels beyond the ligatures, and remove the heart and lungs in one mass, which must be weighed and put into water, to ascertain whether the lungs, with the heart attached, sink or swim. In the next place, put a ligature round the pulmonary vessels, close to the lungs, and cut away the heart by an incision between it and the ligature. Lastly, ascertain the weight of the lungs; whether they sink or swim in water; whether blood issues freely or sparingly when they are cut into; whether any fragments swim in the instances where the entire lungs sink; and in every instance of buoyancy whether fragments of them continue to swim after being well squeezed in a cloth. 64. The general question to be considered in relation to the cause of death is, whether the appearances are such as to be traceable to the act of parturition, or whether they indicate some form of violent death. The directions given in Divisions V., VI., and VII. apply to infants as well as adults; but the following points are specially to be noticed in cases of supposed infanticide:
