Infection in the submasseteric space is discussed, and the conditions predisposing to spread of infection in this direction are mentioned. Differential diagnosis of infection in this space, with special mention of its diagnosis from parotid infection, is discussed, together with indications as to the lines of treatment for such a condition. The importance of a very critical c.linical examination is stressed, since the condition can easily be overlooked and the precise spread of infection can be mistaken. P. A. T.
