a mouth wanting its upper border ; a line formed by the itt^ 

 ferior half of the orbicularis oris muscle showed where the 

 opening for a mouth would have been, had not something 

 arrested the farther deVelopement of the parts ; it was placed 

 at the upper part of the pharynx, but was completely shut by 

 cellular membrane : attached to the angles of this inferior 

 labium were two very small buccinator muscles ; and it had 

 two depressors veiry well defined. There were myo-hyoidei 

 muscles; and the muscles situated between the os hyoides^ 

 thyroid cartilage, cricoid cartilage, and sternum, were distinct 

 and perfect. The larynx and trachea were also perfect. 

 The oesophagus was large, and commenced from a circular 

 and muscular bag (the pharynx), which was supplied with 

 nerves by two large branches on either side from the par 

 vagum. The stylo-pharyngei muscles were large. Ninth pair 

 „ of nerves very small. Internal 



carotid arteries small, and 

 entered the cranium through 

 the foramina, 7, 7,^. 86. All 

 the parts below the os hyoides 

 i^were perfect. 



I now come to the description 

 'of the bones of this faceless 

 head : and here we find more 

 a want of parts than a great 

 deviation from the natural con- * 

 formation. It has the six pro- 

 per bones of the cranium ; viz., 

 one OS frontis, two ossa parie- 

 talia, two ossa temporum, and 

 the OS occipitis ; it has also two 

 ossa triquetra. Of the bones 

 common to the cranium and 

 face, it has the os sphenoides 

 otily. 



I shall endeavour to describe individually the bones of this 

 monstrous part i and, first, the os frontis {a, Jigs. 86. and 87.) 

 is situated in front; its superciliary arch {CL*^Jig, 86.), pro- 

 minent, is nearly a semicircle, and projects so as to form the 

 anterior margin and extremity of the head. A thin plate of 

 bone {h,Jig,S6,), the orbital plate, has a large oval foramen 

 (1) in its centre, for the passage of the optic nerve; be- 

 tween this plate and the sphenoid bone [d) is a lacerated 

 foramen (2) for the passage of the nerves to the eye and its 

 muscles. The ossa parietalia (c, c,Jigs. 86. and 87.) are not 

 very unlike the natural form, and have nothing peculiar to
