 a great measure, prepared our decision. Medical writers on the subject of infanticide have very judiciously considered the modes of violent death in new-born children, as divisible into two great classes, viz. those of omission, and those of commission. It will be convenient for us, on the present occasion, to arrange our remarks with reference to such a division.

Death by omission.—For want of due care the child may perish during, or immediately subsequent to, the labour. It may die from suffocation caused by the viscid mucus naturally existing about the pharynx and glottis in newly-born infants getting into the trachea, especially if the infant has lain on its back for some time after its delivery; or suffocation may be occasioned by the discharge of blood from the mother, or by the wet linen over it, collapsing and excluding the air, or by being drawn close to its mouth and nose by the suction of breathing. Children are, moreover, often born with a portion of the membranes over the face, which, if not removed, must impede respiration. In some cases strangulation is produced by the umbilical cord; the livid circle therefore round the neck, which without due consideration, might seem to afford a proof of criminal violence, is to be regarded with reference to the probability of such an occurrence; it is possible, adds Dr. Hutchinson, that the navel-string may be twisted round the neck of the infant, but loosely, until the body is nearly expelled; and then, if the placenta be firmly retained in the uterus, it may become tightened, and cause suffocation. These circumstances may happen when there is no person about the woman to render her proper assistance; and, therefore, careful examination is necessary, in order to ascertain, if, with the livid circle round the neck,
