f Rational Healing" and in the later treatise
"Chronic Ailments and their Homeopathic Cure." These books created such a
widespread sensation that they were at once translated into several
languages and ran through a great number of editions. As a matter of
course, Hahnemann's peculiar theories were violently combated by his fellow
practitioners.

Almost at the same time with the rise of the new science of homeopathy came
Vincenz Priessnitz's innovation of hydropathy or water cure. He established

sanitarium. Similar water-cure establishments were erected by many
imitators and followers in Germany and elsewhere.

Metternich found himself matched by a diplomat even more subtle than
himself. I
