individual is not rouseahle by the application of a stimuli which would awaken a natural sleeper. In severe states of bacterial poisoning coma occurs and is always of grave moment. An example of pur-posely-induced coma is met with in the induction of a general anaesthesia. Inflammation of the brain (meningitis) is frequently associated with deep insensibility, arid in some forms of this serious malady, after months of wavering in the unconscious state between life and death, recovery takes place.

It is impossible to forecast the progress of an individual case, and the outlook, it must he understood, is always grave. What happens to the brain in s- ach cases of head injury is that the physical violence of the accident throws into a state of nervous commotion and shock the vital nerve elements in the brain, and this structure, just as the skin on the surface of the body, suffers widespread bruising and undergoes an appreciable degree of swelling. In cases where , there is actually gross injury to the brain substance recovery is possible. Unconsciousness is a feature of course, belonging to many types of illness. Its technical name is coma.
