Like acute inflammation elsewhere, acute meningitis (non-tuberculous) may be caused by a variety of microbes, the most important being the meningococcus and the pneumococcus. The disease caused by the meningococcus generally occurs in epidemic form, although sporadic cases are not infrequent, and the meningococcus is regarded as the specific cause of epidemic cerebrospinal meningitis. Streptococci and staphylococci also may cause meningeal inflammation, and of late it has been shown that anaërobic bacteria may play the same part. Ghon, Mucha and Müller1 of Vienna describe with great detail the anaërobic bacteria they isolated from a small series of cases of meningitis following chronic infections of the ear. Rist and others have shown that anaërobic bacilli occur to a greater extent than surmised in ear infections so that it would be quite reasonable that such anaërobes should invade the meninges under favorable conditions. This is not the proper place to describe the
