I have seen the convulsions of traumatic meningitis arrested under bromide of potassium, and it is said that recovery from tubercular meningitis (acute hydrocephalus) has followed its use. In support of this statement Dr. John Brunton has recorded four cases (Glasgow Medical Journal, 1873), in which the heads were enlarged, and the symptoms were certainly serious, but there were no convulsions, and the diagnosis must be held rather doubtful (cf. pp. 87, 88).
