In cases of palsy and tremor connected with the action of mercury, sulphur is useful (Lettsom) and deserves trial; it is said also to neutralize acute mercurialism accompanied with salivation, etc., and may be given in 5 to 10 gr. doses at the same time as chlorate of potash. On the other hand, in patients who have taken mercury at some previous period, sulphur, like iodides and other powerful alterants, has sometimes determined a fresh salivation.
