140 Mr. Carlisle's Account of 
which are brought together by their insertions in the front 
part of the head : the apertures called by anatomists meatus 
extern i, are wanting. Immediately between the insertion of 
the ears, an opening presents itself, lined with cuticle, and 
capable of receiving a bougie, the size of the human male 
urethra : this proved to be the common passage to both the 
oesophagus and the trachea. The outer surface of the head is 
regularly clothed with wool ; and there are no appearances of 
abrasion, or mechanical injury, having taken place at an early 
period of its formation ; such as are observable in monsters, 
and perhaps sometimes produced by the rubbing of the umbi- 
lical cord, or by the contiguity of the uterine contents, whilst 
the young animal is yet In a soft state. See Plate IX. Fig 3 , and 
the references. 
The whole of the organs which are naturally found in the 
face, are, in the present instance, defective : no vestiges of the 
eyes, the nose, or any of the apparatus belonging to the mouth, 
are to be seen. The cranium is perfectly formed into hard 
bone, and bears a near resemblance to the head of a tortoise ; 
it is about the size of a plover's egg. The os hyoides, and its 
processes, are in the natural state : there is no other part of 
the tongue. The cartilages of the larynx, together with- their 
muscles and vessels, are in their places, saving the epiglottis, 
which is joined in with the common aperture, making a cartilagi- 
nous ring. The bones, muscles, blood-vessels, and nerves of the 
neck, are natural. Under the skin which lies between the cartila- 
ginous insertions of the outward ears, there is a small depression 
in the skull, in which are lodged three regularly formed bones, 
of a tooth-like structure, immersed in a gelatinous substance, 
like that which is found in the bony part of very young growing
