traordinary freak of nature, was an amalgamation of two children.
From the body of an otherwise perfectly formed child was a
supernumerary head protruding from a broad base attached to the lower
lumbar and sacral region. This cephalic mass was covered with hair
about four or five inches long, and showed the rudiments of an eye,
nose, mouth, and chin. This child was on exhibition when Dickinson saw
it. Montare and Reyes were commissioned by the Academy of Medicine of
Havana to examine and report on a monstrous girl of seven months,
living in Cuba. The girl was healthy and well developed, and from the
middle line of her body between the xiphoid cartilage and the
umbilicus, attached by a soft pedicle, was an accessory individual,
irregular, of ovoid shape, the smaller end, representing the head,
being upward. The parasite measured a little over 1 foot in length, 9
inches about the head, and 7 3/4 inches around the neck. The cranial
bones were distinctly felt, and the top of the head was covered by a
circlet of hair. There were two rudimentary eyebrows; the left eye was
represented by a minute perforation encircled with hair; the right eye
was traced by one end of a mucous groove which ran down to another
transverse groove representing the mouth; the right third of this
latter groove showed a primitive tongue and a triangular tooth, which
appeared at the fifth month. There was a soft, imperforate nose, and
the elements of the vertebral column could be distinguished beneath the
skin; there were no legs; apparently no vascular sounds; there was
separate sensation, as the parasite could be pinched without attracting
the perfect infant's notice. The mouth of the parasite constantly
dribbled saliva, but showed no indication of receiving aliment.

Louise L., known as "La dame a quatre jambes," was born in 1869, and
had attached to her pelvis another rudimentary pelvis and two atrophied
legs of a parasite, weighing 8 kilos. The attachment was effected by
means of a pedicle 33 cm. in diameter, having a bony basis, and being
fixed without a joint. The attachment almost obliterated the vulva and
the perineum was displaced far backward. At the insertion of the
parasite were two rudimentary mammae, one larger than the other. No
genitalia were seen on the parasite and it exhibited no active
movements, the joints of both limbs being ankylosed. The woman could
localize sensations in the parasite except those of the feet. She had
