Phosphorus mirabilis

Kunckel not only prepared phosphorus, but also cast it in molds to obtain the stick phosphorus now familiar to all chemistry students. He also introduced its use as a medicinal, and his famous book on the subject bears the curious title Treatise of the Phosphorus Mirabilis, and Its Wonderful Shining Pills (10). It is pleasant to know that his phosphorus researches were not without reward, for Duke Johann Friedrich of Hanover paid him an annual pension for the rest of his life (9).
