31. _Cure of Urinary Calculi by means of the internal use of the Bicarbonate of Soda._--At a late meeting of the Academy of Medicine, Mr. ROBIQUET read a memoir on the use of this salt in cases of urinary calculi. Having learnt from Mr. DARCET, that the use of the waters of Vichy changes the quality of the urine from acid to alkaline, Mr. R. conjectured, that this effect should be attributed to the bicarbonate of soda contained in them; and from this circumstance, he was led to administer this salt internally, in cases of calculi composed of uric acid. In July last, he made the experiment on a man 74 years of age, who had laboured under symptoms of the disease since the month of February, and in whom, by means of the sound, a small and soft calculus had been detected. Mr. R. ordered him 10 grains of the bicarbonate in the course of the day, dissolved in two pounds of water--prescribing at the same time, hip baths, injections, &c. At the end of fifteen days, much benefit had already resulted from this treatment; and in a month, the patient appeared to be cured. Nevertheless, the remedy was continued until November, when the patient passed through the urethra, a small calculus composed of uric acid, which appeared to have been the nucleus of a much larger one, the exterior strata of which had been worn off. From that period, the patient has not experienced any unpleasant symptom; but the sound was not resorted to, to ascertain whether the first calculus before felt, could be detected.--_Archives Generales, February, 1826._ 32. _Attempt to cure Abdominal Dropsy, by exciting Peritoneal Inflammation._--In the number of the London Medical and Physical Journal for April, 1826, a case of ascites is related by H. R. OSWALD, Esq. in which the cure was attempted to be effected, by exciting peritoneal inflammation. The following symptoms were noticed at the time of application for advice: the abdomen measured nearly six feet in circumference, was exceedingly hard and tense; but not tender. The patient "could hardly walk across her cabin from dyspnoea and debility, and the weight and tension of the tumour; which caused her to bend the body much forward, leaning her hands on her knees. The emaciation was very considerable; the appetite good; thirst considerable; tongue clean; pulse 120, and small; skin dry, harsh, and rough; bowels habitually costive; urine scanty." "This affection commenced about twelve months ago, after an obstruction of the catamenia for nearly a year, arising, as was supposed, from exposure to cold. The swelling was preceded by lancinating pains in the abdominal and lower part of the thoracic cavities, but which, after a few months, ceased entirely; and the disease had, in a chronic manner, gradually arrived at its present oppressive form."
