The waters of Lake Alphius remove white morphew,2956 Varro tells us; who also mentions the fact that one Titius,2957 a personage who had held the prætorship, had a face to all appearance like that of a marble statue, in consequence of this disease. The waters of the river Cydnus,2958 in Cilicia, are curative of gout, as would appear from a letter addressed by Cassius2959 of Parma to Marcus Antonius. At Trœzen, on the contrary, all the inhabitants are subject to diseases of the feet, owing to the bad quality of the water there. The state of the Tungri,2960 in Gaul, has a spring of great renown, which sparkles as it bursts forth with bubbles innumerable, and has a certain ferruginous taste, only to be perceived after it has been drunk. This water is strongly purgative, is curative of tertian fevers, and disperses urinary calculi: upon the application of fire it assumes a turbid appearance, and finally turns red. The springs2961 of Leucogæa, between Puteoli and Neapolis, are curative of eye diseases and of wounds. Cicero, in his work entitled “Admiranda,”2962 has remarked that it is only by the waters of the marshes of Reate2963 that the hoofs of beasts of burden are hardened.
