Note 134 — SECRET POISON.

For the following important information I am indebted to Professor Baldinger:—“There is no doubt that the slow poison of the French and Italians, commonly called succession powder (poudre de la succession), owes its origin to sugar of lead. I know a chemist who superintends the laboratory of a certain prince on the confines of Bohemia, and who by the orders (perhaps not very laudable) of his patron, has spent much time and labour in strengthening and moderating poisons. He has often declared, that of sugar of lead, with the addition of some more volatile corrosive, a very slow poison could be prepared; which, if swallowed by a dog or other animal, would insensibly destroy it, without any violent symptoms, in the course of some weeks or months.”
