Bartels presents a very complete article in which he describes 21 persons born with tails, most of the tails being merely fleshy protuberances. Darwin speaks of a person with a fleshy tail and refers to a French article on human tails. Science contains a description of a negro child born near Louisville, eight weeks old, with a pedunculated tail 2 1/2 inches long, with a base 1 1/4 inches in circumference. The tail resembled in shape a pig's tail and had grown 1/4 inch since birth. It showed no signs of cartilage or bone, and had its origin from a point slightly to the left of the median line and about an inch above the end of the spinal column. Dickinson recently reported the birth of a child with a tail. It was a well-developed female between 5 1/2 and six pounds in weight. The coccyx was covered with the skin on both the anterior and posterior surfaces. It thus formed a tail of the size of the nail of the little finger, with a length of nearly 3/16 inch on the inner surface and 3/8 inch on the rear surface. This little tip could be raised from the body and it slowly sank back. In addition to the familiar caudal projection of the human fetus, Dickinson mentions a group of other vestigial remains of a former state of things. Briefly these are:-- (1) The plica semilunaris as a vestige of the nictitating membrane of certain birds. (2) The pointed ear, or the turned-down tip of the ears of many men. (3) The atrophied muscles, such as those that move the ear, that are well developed in certain people, or that shift the scalp, resembling the action of a horse in ridding itself of flies. (4) The supracondyloid foremen of the humerus. (5) The vermiform appendix. (6) The location and direction of the hair on the trunk and limbs. (7) The dwindling wisdom-teeth. (8) The feet of the fetus strongly deflected inward, as in the apes, and persisting in the early months of life, together with great mobility and a distinct projection of the great toe at an angle from the side of the foot. (9) The remarkable grasping power of the hand at birth and for a few weeks thereafter, that permits young babies to suspend their whole weight on a cane for a period varying from half a minute to two minutes. Horrocks ascribes to these anal tags a pathologic importance. He claims that they may be productive of fistula in ano, superficial ulcerations, fecal concretions, fissure in ano, and that they may hypertrophy and set up tenesmus and other troubles. The presence of human tails has given rise to discussion between friends and opponents of the Darwinian theory. By some it is considered a reversion to the lower species, while others deny this and claim it to be simply a pathologic appendix.
