Luminal has been used in the treatment of insane epileptics in a number of patients at Claybury Mental Hospital during the last three years. A perusal of the results obtained shows that this drug would appear to have a definite value in diminishing the number of seizures, but that it hardly deserves the encomiums showered upon it in some quarters, e.g., it does not reduce fits to the level of “rare occurrences,” and in some cases the fit-incidence is increased during its administration.
