CHAP. 17.—WATERS WHICH PRESERVE THEIR WARMTH FOR THREE DAYS.

At Crannon2982 there are certain hot springs, though not at boiling heat, the water of which, mixed with wine, preserves it warm in the vessels for a period of three days. The same is the case, too, with the springs of Mattiacum2983 in Germany, beyond the river Rhenus, the water of which retains its boiling heat three days. The margin of these springs is covered with pumice, formed by the action of the water.
