Human Acephalus, born along with a well-formed child. the observations which we know of it are ot twins, and in one case of three children born at one birth. In many it is proved that the mother of the acephalus has been often fecun- dated. They are rarely full-grown at birth, and they have in most instances a placenta common to them and the well-formed child, but with a separate cord ; the foetal membranes also appear to be common to both. The cord of the acephalus contains sometimes two, sometimes three or four vessels (T. II. Kalck). The integuments of the monster, truncated at its upper part, are irregularly tumified, by a eminences covered by the skin. Fig. 617. , the right foot with five; b, the left, with lar»e quantity of thick, pale, or yellowish 'three toes; A, the female genitals; i, the anus; subcutaneous cellular tissue. Interiorly there e, tumor formed tty the umbilical cord; d,e,f,g, are lumbar vertebras, with a pelvis, and the bones and muscles of inferior limbs, besides the spinal marrow and its nerves; the lumbar and sacral parts of the sympathetic nerve ; blood-vessels without a heart, of which the arteries are connected with the umbilical ar- teries, and the veins with the umbilical vein ; a loop of intestines ; uropoietic, and genital parts. All the other parts are wanting. Fifth Type. —Acephali in which the trunk is much more developed, with an imperfect tho- rax, composed of some dorsal vertebra; and ribs. The superior limbs are wanting.— The only difference between this and the preceding type is in the more complete trunk, there being a thorax superadded to the abdomen. In all the other points the structure re- sembles that of the fourth type j they are Fig. 618.
