Dr. B. became affected with calculus after the age of 60 years, having previously passed several renal calculi, and was operated on by the lithotritic apparatus. The stone was smashed, but several of the fragments could not be discharged afterwards. He was then conveyed in a kind of litter many hundreds of miles to Carlsbad, where he took the waters under the direction of Dr. De Carro. On the third day of taking the Theresebrunn, and that in small quantities, Dr. B. became affected with fever, such as he experienced after the operation of lithotrity. This was relieved by copious perspirations. Returning to the waters, a similar attack of fever was kindled up on the fifth day—but with it the expulsion of several fragments of stone, and much solace in the organ. The fragments, which had hitherto been of a dark brown colour, were now white, and their surfaces smooth and polished. The white colour was found to penetrate to some depth from the surface. Dr. B. changed from one spring to another of higher temperature, till he finished with the Sprudel. At each of the sources he passed pieces of stone, and after their disappearance for a fortnight, the bladder was explored, and no more calculi were discoverable. All uneasiness in the bladder ceased from this time. Dr. Creutzburg made some experiments on urinary calculi subjected to the action of the Carlsbad waters, and the results appear to be favourable to the idea that these waters are beneficial in calculous complaints. And now, when lithotrity is so frequently employed, instead of lithotomy, these waters may prove eminently useful in polishing and softening the fragments left after the operation. But the waters of Carlsbad do not limit their powers to the solution or expulsion of vesical calculi; they have done wonders in people afflicted with biliary concretions. Dr. De Carro had a patient, aged 40 years, who evacuated daily, by means of the waters, not only large quantities of gravel, but numbers of gall-stones, of various shapes and sizes. Liver-complaints occupy a considerable figure among the maladies which are treated at Carlsbad—and biliary calculi are very frequently observed there. Dr. De Carro has related numerous instances where the baths and the waters of Carlsbad have appeared to dislodge the gall-stones, and carry them off by the bowels. The Carlsbad baths, which are now much more used than formerly, often bring forward masked gout, rheumatism, or neuralgic pains that had lain more or less dormant in the constitution for months or years. Before quitting these celebrated waters, I must take a short notice of a little work just published by a rising young physician of Carlsbad, whose acquaintance I had the pleasure of making there.
