Pancoast gives an extensive report of Millie-Christine, who had been extensively exhibited in Europe and the United States. They were born of slave parents in Columbus County, N.C., July 11, 1851; the mother, who had borne 8 children before, was a stout negress of thirty-two, with a large pelvis. The presentation was first by the stomach and afterward by the breech. These twins were united at the sacra by a cartilaginous or possibly osseous union. They were exhibited in Paris in 1873, and provoked as much discussion there as in the United States. Physically, Millie was the weaker, but had the stronger will and the dominating spirit. They menstruated regularly from the age of thirteen. One from long habit yielded instinctively to the other's movements, thus preserving the necessary harmony. They ate separately, had distinct thoughts, and carried on distinct conversations at the same time. They experienced hunger and thirst generally simultaneously, and defecated and urinated nearly at the same times. One, in tranquil sleep, would be wakened by a call of nature of the other. Common sensibility was experienced near the location of union. They were intelligent and agreeable and of pleasant appearance, although slightly under size; they sang duets with pleasant voices and accompanied themselves with a guitar; they walked, ran, and danced with apparent ease and grace. Christine could bend over and lift Millie up by the bond of union. A recent example of the pygopagus type was Rosa-Josepha Blazek, born in Skerychov, in Bohemia, January 20, 1878. These twins had a broad bony union in the lower part of the lumbar region, the pelvis being obviously completely fused. They had a common urethral and anal aperture, but a double vaginal orifice, with a very apparent septum. The sensation was distinct in each, except where the pelves joined. They were exhibited in Paris in 1891, being then on an exhibition tour around the world. Rosa was the stronger, and when she walked or ran forward she drew her sister with her, who must naturally have reversed her steps. They had independent thoughts and separate minds; one could sleep while the other was awake. Many of their appetites were different, one preferring beer, the other wine; one relished salad, the other detested it, etc. Thirst and hunger were not simultaneous. Baudoin describes their anatomic construction, their mode of life, and their mannerisms and tastes in a quite recent article. Fig. 42 is a reproduction of an early photograph of the twins, and Fig. 43 represents a recent photograph of these "Bohemian twins," as they are now called.
