COMMUNICATIONS AND CONSULTATIONS. 
At the base of the skull the body of the sphenoid bone (near to 
the ethmoid) was fractured transversely through its whole sub- 
stance. There were also fractures along the pterygoid fissures 
quite into the foramina lacera basis cranii, completely separating 
the body of the sphenoid bone from its alae, and on the off side 
fissure the bones were comminuted into six or eight pieces, which 
had lacerated the brain and bloodvessels. 
There was also a fracture on the near side, extending from the 
foramen lacerum basis cranii, between the anterior mastoid process 
of the temporal bone and the auricular petrous portion of the same, 
across to the parietal bone ; and within the cranium at this place 
there was a shell of bone the size of one’s finger-nail that had 
penetrated the brain. 
On looking inside of the cranium, several thin pieces of the eth- 
moid bone, near to the great fracture in the sphenoid, were seen 
loose and projecting inwardly, and surrounded by a good deal of 
blood. On the near side the auricular petrous portion of the tem- 
poral bone was completely fractured and separated from the sur- 
rounding parts. The frontal, maxillary, and other sinuses, were 
filled with coagulated blood ; there was also on the off side a 
good deal of blood in the great temporal fossa, produced, no doubt, 
by the fracture of the side of the sphenoid bone. In consequence 
of these fractures a good deal of play was allowed between the 
bones of the skull on the near side, as, by pulling at the odontoid 
processes we could force open the fractures considerably.

A singular Case of Ulceration of the Penis. 
THERE is a case of ulceration of the penis which I have, an 
account whereof will, perhaps, be interesting to you. A black cob 
gelding, the property of Mr. Richard Tomlinson, of Rowsley, about 
three miles from Bakewell, had, for three years, been affected 
with ulceration of the penis, and had been gradually getting worse, 
being frequently attended with haemorrhage that threatened to 
destroy him, and which on one occasion, in the beginning of
