The varying results obtained in the treatment of chorea must be connected with its varying pathology, which is not yet well understood. I have seen a few patients recover rapidly under treatment by bromide, but the majority are too anaemic or asthenic to bear it well; hence, it is not surprising that Dr. R. Reynolds found it even prejudicial in some cases.

Dr. Ramskill tried fully the potassium salt, "and with strong prejudice in its favor," but without satisfactory result. Camphor bromide is said to have acted better (British Medical Journal, i., 1877), but has not done so in my experience.
