phosphate has been adopted. The name of Dr. James's Powder as a synonym has now been dropped.
It has been suspected that Dr. James did not actually invent the powder, but adopted it from an Italian recipe which was certainly popular when he introduced it. In Colborne's "English Dispensatory," published in 1756, directions are given for making Mr. Lisle's Powder for Fevers, sent to the author, he says, by a friend in Italy. Hartshorn shavings are to be boiled in a large quantity of water for six hours; the water is then to be strained off, the hartshorn to be dried by a slow fire, and finely powdered. Equal weights of this and of diaphoretic antimony are to be heated in a crucible, stirring all the time with a long iron, for eight hours or as long as it smokes. This powder is said to have been in great reputation for some years, having been successful in cases when hardly any hope seemed left. Twenty grains is indicated as a moderate dose at not less than six hours' interval, and it is noted that the first and second doses often cause vomiting.
Whether this was the original of James's invention or not it may be presumed that the formula was a guide to those doctors and chemists who were busying themselves with the analysis of his powder. Another claim of precedence was made by a patent medicine dealer of London named William Baker, who alleged that Dr. James's process was an infringement of a patent or at least a copy of a formula invented by a German named Schwanberg.
Medical opinion has varied concerning the relative merits of the proprietary medicine and its official imitation. Christison in his Dispensatory (1842) expresses an opinion which was very generally held at least in his time when he says, "No one can deny that
