EXPERIMENTS ON THE ACTION OF CERTAIN DIURETICS (CITRATE AND ACETATE OF POTASH, SPIRITUS ETHERIS NITKOSI, AND OIL OF JUNIPER) ON THE URINE IN HEALTH. BY F. B. NUNNELEY, M.D. LOND., ASSISTANT-PHYSICIAN TO THE VICTORIA PARK HOSPITAL. COMMUNICATED BY JOHN ERIC ERICHSEN, Esq. Received November 8th, 1869.-Read February 8th, 1870.

As clinical evidence is in favour of the diuretic power of these medicines in some diseases attended by anasarca, one of the therapeutical questions to be considered is whether the increased secretion occurs from their action on the portion of renal structure which remains anatomically unchanged, and quite irrespective of the altered condition of the blood; or |
