of Human Monstrosity. 221 



when assigned to estimate? It is with pleasure that I embrace 

 an opportunity of proving-, as I hope to do, that, in one instance 

 at least, the apparently excessive development is referable to the 

 usual laws. 



The monstrous production which I proceed to describe, con- 

 sists of the junction of two males by the head, neck, sternum, 

 and abdomen of each, as low down as the passage for the common 

 umbilical chord. From this point the bodies are separate. The 

 external organs of generation are natural, the testes on the point 

 of descending into the scrotum, the opening of the rectum, perfect 

 in both. There are two arms, and two legs to each fetus, and 

 the whole body of each, from the umbilicus downward, is well 

 nourished, and very perfectly moulded. 



The connexion is of this kind. The spine of one foetus is to 

 the extreme right, of the other to the extreme left. The ribs from 

 each spine arch towards a mid plane, and thus form a body with 

 breasts on each front common to the two. The occiput of each 

 arches from its spine, upwards, backwards, and then forwards, 

 until it meets the corresponding parts from the other spine. And 

 then a mixing together of the two heads takes place. The faces. 

 in this operation are not destroyed, for the right portion of the 

 face of one foetus joins with the left portion of the face of the 

 other, to make up two anomalous countenances, which look 

 forward and backward, Janus-like, in a direction perpendicular 

 to the common plane of the spines. 



One of these faces is more perfect than the other. There are 

 two ears to each, and a mouth: over the mouth is, in each, an 

 eye-ball, surrounded by four eye-lids, of which the external angles 

 are naturally united, and the internal angles meet in the mid line 

 of the face, above and below the eye-ball. In the more perfect.
