In a few cases of Bright's disease, narrated by Dr. C. Paul, albumen disappeared from the urine during treatment by oxygen. This occurred also in the often-quoted case observed by Kollman and Eckart (Schmidt's Jahrb., 1865). More recently, Dujardin Beaumetz reports a case "in the last stage," and in which every diuretic had proved useless, and yet, twenty-four hours after inhaling oxygen, the albumen disappeared, and was still absent twelve days afterward when the case was reported (Medical Record, March, 1879). Other physicians, while recording similar cases in their own experience, stated that the good result was not of long duration.
