The feasibility of the operation of separating them was discussed by many of the leading men of America, and Thompson, Fergusson, Syme, Sir J. Y. Simpson, Nelaton, and many others in Europe, with various reports and opinions after examination. These opinions can be seen in full in nearly any large medical library. At this time they had diseased and atheromatous arteries, and Chang, who was quite intemperate, had marked spinal curvature, and shortly afterward became hemiplegic. They were both partially blind in their two anterior eyes, possibly from looking outward and obliquely. The point of junction was about the sterno-siphoid angle, a cartilaginous band extending from sternum to sternum. In 1869 Simpson measured this band and made the distance on the superior aspect from sternum to sternum 4 1/2 inches, though it is most likely that during the early period of exhibition it was not over 3 inches. The illustration shows very well the position of the joining band. The twins died on January 17, 1874, and a committee of surgeons from the College of Physicians of Philadelphia, consisting of Doctors Andrews, Allen, and Pancoast, went to North Carolina to perform an autopsy on the body, and, if possible, to secure it. They made a long and most interesting report on the results of their trip to the College. The arteries, as was anticipated, were found to have undergone calcareous degeneration. There was an hepatic connection through the band, and also some interlacing diaphragmatic fibers therein. There was slight vascular intercommunication of the livers and independence of the two peritoneal cavities and the intestines. The band itself was chiefly a coalescence of the xyphoid cartilages, surrounded by areolar tissue and skin. The "Orissa sisters," or Radica-Doddica, shown in Europe in 1893, were similar to the Siamese twins in conformation. They were born in Orissa, India, September, 1889, and were the result of the sixth pregnancy, the other five being normal. They were healthy girls, four years of age, and apparently perfect in every respect, except that, from the ensiform cartilage to the umbilicus, they were united by a band 4 inches long and 2 inches wide. The children when facing each other could draw their chests three or four inches apart, and the band was so flexible that they could sit on either side of the body. Up to the date mentioned it was not known whether the connecting band contained viscera. A portrait of these twins was shown at the World's Fair in Chicago.
