MY DEAR SIR,—In my little work on the waters of this place, I find I have entirely omitted to mention the subject of PARALYSIS, occasioned by mechanical injuries, and especially those which sometimes follow difficult accouchements. On this topic, Dr. Siebold, one of the most eminent obstetrical practitioners in Germany, has published his opinions, and strongly recommends the baths of Teplitz, as more efficacious than any other remedy. I omitted also, in my “ENVIRONS OF TEPLITZ,” to allude to the mineral waters of Püllna, Sedlitz, and Saidschitz, so celebrated all over Europe, and which are situated at four leagues from Teplitz, on the Carlsbad road. The village of Püllna lies in a beautiful plain, two or three hundred yards from the Chaussee, on the right; and the mineral springs themselves are close to the road. I refer you to Mr. Spitta for further particulars. P.S.—A rail-road is forming between Dresden and Prague, to run by Teplitz. This will render the communication between London, Teplitz, and Carlsbad, extremely easy and quick. I am, dear Sir, Your’s truly, THEODORE L. RICHTER, M.D. _Teplitz, 18th Sept. 1840._ _Extract of a Paper of Mr. Spitta’s on the Waters of Püllna, &c._ Within a morning’s drive from Teplitz, are situated three mineral springs, little known, yet in many respects extremely interesting—Püllna, Saidschitz, and Sedlitz. They all yield a water of a similar nature, rich in the sulphates of magnesia and soda; and which is so peculiarly bitter, as to have acquired the title of “Bitterwasser.” Having heard so much of this bitterwasser in Germany, and of the powders of Sedlitz at home, I was anxious to ascertain the true nature of the springs; and see if they really afforded a mineral water so agreeable and salutary as we get in England by dissolving our “genuine _Sedlitz_ powders.” I proposed an excursion, and Dr. Richter, of Teplitz, with his usual urbanity, kindly accompanied me. So near as Teplitz is to these springs, it will doubtless appear strange to others as it did to me, that, no one, not even the people at the post-office, where we ordered the carriage, could tell us their exact position. So great a traffic! so much Sedlitz salt prepared! one hardly knew how to account for such ignorance. Püllna, indeed, they had heard of; for, being on the road from Carlsbad to Teplitz, it could not well have been overlooked; Saidschitz was conceived, by possibility, to exist; but, as to poor Sedlitz, where all our powders come from, its very existence was denied; nor was it, till we were within a mile, that we learnt its situation from a few wandering peasants.
