Albuminuria and the Duration of Albuminuria in Cholera

a mere turbiditj7 to a distinct precipitate. The degrees of albumosuria and albuminuria were not proportional to each other in all my cases. In a few cases there was a mere trace of albumose, while the quantity of albumen was large. What is called here albumose was characterized by the following tests :? (1) Not precipitated by heat. (2) Precipitated by HNoa. This precipitate is soluble on boiling and reappears on cooling. (3) The precipitate with HNos was granular under the tniroscope and was never crystalline. In some of my cases, the urine was boiled with a 10 per cent, solution of Trichloracetic acid and filtered hot. The filtrate gave a precipitate after cooling for 24 hours. This precipitate was granular under the microscope and soluble on boiling. The precipitate with HNoa or Trichloracetic acid never gave the murexide test for urates or uric acid. The average period of albuminuria in my cases was much greater than that described by any previous observer. Calculating from my cases, it will be seen that the average period during which albumen is present in the urine of
