“_Concentrated Form._”—This was supplied for export to the colonies, was a moist coarse brown crystalline powder in hermetically-sealed tins, with directions enclosed for dissolving in water. A quarter package (the smallest supplied) contained 11¼ ounces, and was directed to be dissolved in one pint of warm water. The resulting mixture was found to measure 25 fluid ounces. From the formula given below it will be seen that the mixture thus prepared differed from the one issued for home consumption in two important particulars: (_a_) ammonium bromide was absent, (_b_) the dose of potassium bromide was considerably larger than that of the total bromides in the latter. Is this a form of colonial preference? or is it that our brothers beyond the sea are more robust and hence proof against the depressing influence of potassium salts? The formula of the powder ascertained by analysis was: Potassium bromide 61 parts. Moist brown sugar 39 ” The calculated composition of the finished mixture was: Potassium bromide 120 grains. Moist brown sugar 77 ” Water to 1 fluid ounce. The dose of the mixture directed to be taken was one teaspoonful in the morning and two at night. The price charged for a quarter package was 15s., but the estimated cost of the contents is about 8d. Such then are these secret remedies for epilepsy; with one exception they are weak preparations of well-known drugs supplied at considerably more than the usual cost, and administered without that careful adjustment of dose to the needs of the particular patient which is, after all, the most essential part in the treatment of epilepsy by bromide salts. The exception contains an old-fashioned herb once praised by the superstitious but abandoned time and again even by them; it has never been shown to possess any definite therapeutic properties and was long ago discarded by the medical profession because it was found useless.
