The NEUBRUNN is separated from the former source only by a covered walk, and marks 144° of heat. It did not appear to me to be so much in vogue at this fashionable watering-place, as the Muhlbrunnen. Behind the Neubrunn there is a hill, cut into terraces and gravelled walks, where rises the THERESIENBRUNN—a spring much frequented by the ladies, and indeed by both sexes. The temperature is only 134° of Fahrenheit, and the water is almost tasteless. These three (with the Hygienequelle, close to the Sprudel) are the chief springs, which are much frequented by the great mass of bibbers at Carlsbad.[70] The waters of all the springs deposit abundance of calcareous matters, which crystallize in stalactites of all shapes and hues, called _Sprudelstein_, and give employment to numerous hands in the formation of snuff-boxes and various kinds of bijoux.[71] As incrustations form on the surfaces of any woody, mineral, or vegetable substance immersed in these waters, a fear is sometimes engendered in timid minds that similar incrustations might form in the stomach, bowels, or kidneys of those who drink them! It has been proved by Dr. De Carro and others, that the stalactitious deposits will not take place on any _animal_ substance, with the exception of the teeth. Even here, the quantity of stony matter is so small in a dozen beakers of the Sprudel, that nothing is to be apprehended to the teeth on this score. It would, perhaps, be a happy circumstance for Germany, if the Sprudel had the faculty of encrusting the teeth with a calcareous enamel! If such were the case, the whole of the five springs at Carlsbad would be insufficient to supply dentrifice varnish enough! A serio-comic anecdote is related of a hypochondriac, who had drunk of these waters for some weeks before the _petrifying_ thought flashed across his mind, (in consequence of some uneasy sensations in his stomach) that incrustations were forming in his interior. From that moment he became firmly convinced that snuff-boxes, heads of canes, Madonnas, and even crucifixes, were torturing his entrails! He drenched himself daily with drastic purgatives—but, unfortunately, no stalactites came forth: on the contrary, his inward pains and miseries were increased by the very means that were employed to expel the enemy! Whether he ever recovered from his imaginary sufferings is not known.
