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.
