SECTION I. INJURIES OF THE ORBIT. I Under the head of Injuries, I may mention, first of all. Contu- sion producing inflammation and caries of the bones forming the edge of this cavity, Fractures, and Penetrating Wounds of the Or- bit. Incised wounds, laying open the orbit, must from their nature be rare ; yet some interesting cases, even of this sort, are recorded. Many Gunshot wounds of the orbit are related. Indeed, numerous examples of the perforation of every part of the face and head Ijy balls, must present themselves after a battle to the notice of mihta- ry surgeons. It is not my intention at present to treat of injuries of the parts contained within the orbit. Yet it is impossible altogether to avoid noticing the effects produced on the contents of this cavity, while considering injuries of the orbit itself; or, while treating of wounds penetrating the walls of the orbit, to pass over in silence the inju- ries which in this way, the brain and other surrounding organs may sustain. Cases occur, indeed, in which it is doubtful, to the injury of what particular part, without, within, or beyond the orbit, the con- sequences of an injury ought to be attributed. Amaurosis, for ex- ample, one of the chief consequences to be apprehended from wounds of the orbit, is sometimes owing to injury of the branches of the
