Notes :

Through the courtesy of Dr. Holcomb, of New York City, I have the opportunity of presenting this monster, which in the text-books is described as a synkephalus. It is formed by the fusion of two bodies. In this specimen it is an asymmetrical synkephalus, having one head, four lower and four upper extremities. The thorax is double; the vertebra; from the pelvis up are double; the umbilicus is single. The viscera have not as yet been examined; but in similar cases, reported in Ahlfeld's book, and pictured on Plate XV., Figs. 1 and 2, the stomach and oesophagus are usually single, the kidneys and genital organs double. The thorax may be single or double, and the thoracic contents in accordance. The cerebrum is usually single; the cerebellum, medulla, pons, and corpora quadrigemina double.—Page 822.
