I shall add but one word on the medical properties of the bitterwassers. As a glance at the analyses would anticipate, they are solvent and diuretic. They are aperient, however, without being at the same time stimulating; as is the case with the Salzbrunn at Franzensbad, from its abundance of carbonic acid, and with the Carlsbad water, from its heat. They, especially the Püllna, which is employed the most frequently, are too strong to be taken pure. One-third to the half of a dumpty bottle, with an equal quantity of luke-warm water, will be found an efficient and tolerably palatable dose. A medicine of this kind, repeated regularly every morning, is of the greatest advantage to persons habitually costive from sluggishness of action in the muscular fibre of the intestine, brought on by sedentary lives, much study at late hours, &c. If this state be accompanied with hæmorrhoids, the remedy, from its gentle effect, is still more valuable. In congested states of the liver and spleen, they are efficient; blood is determined to the intestine, to the relief of the portal vessels. In actual jaundice, they are even prescribed with advantage. In mentioning the leading properties of these bittersprings, I do not think I should be inclined (were he willing) to send a patient there; for I should expect to hear, either that he had been upset in his journey, or starved on his arrival. But I have another motive. From the very nature of the water, containing so little carbonic acid, and so little iron, it can be imitated with great success. I saw Struve’s process at Dresden; and I have taken that made at the Brighton spa, with all the effect of the original and genuine Püllna. It seemed to me a remedy worthy of more patronage than it had hitherto received. Finally, I would not wish, from what I have said, to depreciate the character of our very old and tried friend, the “Sedlitz.” On the contrary—I hold him in much veneration. One word only I would add to his title—I would call him the “GENUINE (LONDON) SEDLITZ POWDER.” ROBERT J. SPITTA. P.S.—I may as well state here, for the information of travellers, and especially of invalids, the ready means of communication that now exist, independent of the rail-road abovementioned. From Teplitz to Tetchen 4 hours. From Tetchen (through the heart of Saxon Switzerland by steamer) to Dresden 12 ” From Dresden to Magdeburg (passing through Leipzig—rail-road) 8 ” Magdeburg to Hamburg (steam) 14 ” Hamburg to London 48 ” --- Total 86 hours. ---
