Leopold und Leisewitz, Geburtshilflicher Röntgen-Atlas. Römmler & Jonas, Dresden. Lettering attached to the print is on a separate sheet and reads: "Dipygus parasiticus. A parasitic form of the duplicitas anterior. As the parasite is almost completely developed with exception of neck and head it adheres nearer the head. Two well-developed upper extremities can be discerned with clavicles, traces of the scapulae, upper-arm bones, fore-arm bones and hands; the two claviculae of the parasite are connected with the sternal ends of the claviculae of he autosite, so that the growth of the one with the other at the sternum may be assumed. In the parasite the vertebra is missing, the pelvis is well developed as well as the lower extremities; also the clearly discernible male genitals, as well as those of the autosite, are well developed. The thorax, the neck vertebra are missing, as indeed are any signs of a neck. The rudimentarily developed head of the parasite is situated on the face of the autosite, which can only be recognised with difficulty, in the same manner as with the Prosopo-thoracopagus. The lower jaw-bones are joined together; the other shadows of the head bones are not easy to distinguish. The extreme outside bone on which the right arm of the parasite is leaning, appears to be a skull bone (occiput?). Underneath this is seen a shadow of flesh, parts that belong to the ears of the parasite which have grown together. The otherwise normally buiilt autosite corresponds with a foetus in the 8th month. The parasite is without navel-string, therefore nourishment came from the autosite."
