In chronic and asthenic cases of impaired motor power, the use of sulphur internally and externally deserves a fair trial. Dr. Graves was accustomed to depend upon it after a course of strychnia. Wetzler has recorded four cases of progressive muscular palsy benefited by warm sulphur-baths and the administration of the water at Aix-la-Chapelle (British and Foreign Review, ii., 1856, p. 457), and in his treatise (1862) has added several other cases. Althaus found these remedies useful in locomotor ataxy (Lancet, ii., 1865). I have also seen some advantage from them in the latter condition.
