Below this point they had a common trunk and single lower extremities. The right one, christened Ritta, was feeble and of a sad and melancholy countenance; the left, Christina, was vigorous and of a gay and happy aspect. They suckled at different times, and sensations in the upper extremities were distinct. They expelled urine and feces simultaneously, and had the indications in common. Their parents, who were very poor, brought them to Paris for the purpose of public exhibition, which at first was accomplished clandestinely, but finally interdicted by the public authorities, who feared that it would open a door for psychologic discussion and speculation. This failure of the parents to secure public patronage increased their poverty and hastened the death of the children by unavoidable exposure in a cold room. The nervous system of the twins had little in common except in the line of union, the anus, and the sexual organs, and Christina was in good health all through Ritta's sickness; when Ritta died, her sister, who was suckling at the mother's breast, suddenly relaxed hold and expired with a sigh. At the postmortem, which was secured with some difficulty on account of the authorities ordering the bodies to be burned, the pericardium was found single, covering both hearts. The digestive organs were double and separate as far as the lower third of the ilium, and the cecum was on the left side and single, in common with the lower bowel. The livers were fused and the uterus was double. The vertebral columns, which were entirely separate above, were joined below by a rudimentary os innorminatum. There was a junction between the manubrium of each. Sir Astley Cooper saw a monster in Paris in 1792 which, by his description, must have been very similar to Ritta-Christina.
The Tocci brothers were born in 1877 in the province of Turin, Italy. They each had a well-formed head, perfect arms, and a perfect thorax to the sixth rib; they had a common abdomen, a single anus, two legs, two sacra, two vertebral columns, one penis, but three buttocks, the central one containing a rudimentary anus. The right boy was christened Giovanni-Batista, and the left Giacomo. Each individual had power over the corresponding leg on his side, but not over the other one.
Walking was therefore impossible. All their sensations and emotions were distinctly individual and independent. At the time of the report, in 1882, they were in good health and showed every indication of attaining adult age. Figure 48 represents these twins as they were exhibited several years ago in Germany.
McCallum saw two female children in Montreal in 1878 named Marie-Rosa Drouin. They formed a right angle with their single trunk, which commenced at the lower part of the thorax of each.
They had a single genital fissure and the external organs of generation of a female. A little over three inches from the anus was a rudimentary limb with a movable articulation; it measured five inches in length and tapered to a fine point, being furnished with a distinct nail, and it contracted strongly to irritation. Marie, the left child, was of fair complexion and more strongly developed than Rosa. The sensations of hunger and thirst were not experienced at the same time, and one might be asleep while the other was crying. The pulsations and the respiratory movements were not synchronous. They were the products of the second gestation of a mother aged twenty-six, whose abdomen was of such preternatural size during pregnancy that she was ashamed to appear in public. The order of birth was as follows: one head and body, the lower extremity, and the second body and head.
CLASS VII.--There are many instances of bicephalic monsters on record. Pare mentions and gives an illustration of a female apparently single in conformation, with the exception of having two heads and two necks. The Ephemerides, Haller, Schenck, and Archenholz cite examples, and there is an old account of a double-headed child, each of whose heads were baptized, one called Martha and the other Mary. One was of a gay and the other a sad visage, and both heads received nourishment; they only lived a couple of days. There is another similar record of a Milanese girl who had two heads, but was in all other respects single, with the exception that after death she was found to have had two stomachs. Besse mentions a Bavarian woman of twenty-six with two heads, one of which was comely and the other extremely ugly; Batemen quotes what is apparently the same case--a woman in Bavaria in 1541 with two heads, one of which was deformed, who begged from door to door, and who by reason of the influence of pregnant women was given her expenses to leave the country.
