1. _Average Length of Body._--Nineteen inches. 2. _Average Weight of Body._--About seven pounds. 3. _Eyes._--The pupillary membrane is not found in the mature child. 4. _Navel._--Said to be exactly midway between the pubes and the ensiform cartilage. 5. _External Genitals._--Testicles found in the scrotum, and the labia majora cover the vagina and clitoris. 6. _Os Femoris._--Ossification of the inferior femoral epiphysis. The osseous nucleus measures from three-quarters of a line to three lines in diameter. CAUSE OF DEATH TO THE FŒTUS Death may be due to-- I. Immaturity on the part of the fœtus. II. Complications occurring during or immediately after birth. III. Congenital disease in one or more of the fœtal organs. IV. Neglect or exposure, constituting “Infanticide by Omission.” I. Immaturity on the part of Fœtus.-From some cause or another, the child may die immediately after birth, in spite of every attempt to save it. In many of these cases no disease adequate to account for death can be detected. II. Complications occurring during or immediately after Birth.--(1) Unavoidable or inherent in the process of parturition. (2) Induced with criminal intent, constituting “infanticide by commission.” 1. _Unavoidable or Inherent in the Process of Parturition._--The immediate cause of death may be either maternal or fœtal. In the former, the presence of tumours in the pelvic passages, or disease of the bones, causing a narrowing of the canal, may lead to fatal compression of the head of the child. Death may also be due to protracted labour from debility on the part of the mother, or she may suddenly faint after delivery. A congested state of the brain may be present in these cases. In the latter (fœtal), pressure on the umbilical cord from malposition of the child during labour, or an abnormal increase in the size of the head, may cause death. There is also a greater mortality, both during and after delivery, among male than female children. The child may be also accidentally suffocated in the fæces of the mother, or in the fold of her dress; or it may be born while the woman is straining at stool, and be drowned in the contents of the pan. Husband once met with a case of accidental death of a child from suffocation in the drawers of the mother, who persisted, from motives of delicacy, in wearing those articles of dress during her confinement. Death may also result from strangulation, occasioned by the pressure of the funis round the child‘s neck. The death in this case can scarcely be considered as due to strangulation, as the child had never breathed, but it is probably the result of the arrest of the flow of blood along the cord, from the tightness of the folds round the neck. Some congestion of the brain may, however, be found resulting from the pressure on the vessels of the neck. Lastly, death may
