The bromide of ammonium has been found extremely useful in acute rheumatism by Da Costa (American Journal, April, 1871). Gueneau de Mussy also praises the bromide for the same malady. For subacute cases, for rheumatic gout, and for the resulting stiffness and nodosity of joints, the bromide of lithium is recommended (Bartho-low). This remedy is certainly valuable for relieving the wakefulness and delirium of rheumatic fever; morphia may occasionally be well combined with it.
