Dr. gave his name to a fever powder, since highly celebrated. With a disingenuity highly reprehensible he seems to have deviated from his original idea, and sold a medicine under the authority of a patent very different from the specification. He directy the antimony to be calcined in a flat unglazed earthen vessel, adding any"animal oil, or salt;" then to be boiled in melted nitre, and the powder separated by solution. The powder was found to contain no animal oil or salt, but an animal earth, which, though it may be now called a salt, had scarcely that appellation in Dr. James's time. He adds, that thirty grains of the powder, with one grain of mercury, was a moderate dose; but ten grains of the present powder, without the mercurial is now such. Dr. Pearson, has, however, in the Philosophical Transactions, taught us its real nature, and it is nearly imitated in the pulvis antimonialis of the London Dispensatory. This preparation is, however, more active on the stomach and bowels than the powder of James.

Dr. Monro asserts, that Dr. James trusted to the bark in the cure of fevers rather than to his antimonial, which he only employed to clear the first passages. On this we can only remark, that had he really done so wc should have heard little of his success.
