URINE-FORMATION IN CRAYFISH KIDNEY 245 RESULTS Excretion of Inulin In all the preliminary experiments, the injection of cc. 5 per cent inulin in crayfish-saline resulted in a renal output of inulin. Thus, the urine, which was collected by suction from the nephropores, gave a positive result with Benedict's qualitative only after acid-hydrolysis. Before the introduction of inulin the urine was non-reducing even with acid-hydrolysis. 900 700-. FIG. 5. The concentration of creatinine in the blood in mg. per cent (ordinate)

The concentration of creatinine in the blood in mg. per cent (ordinate) as a function of the time in hours (abscissa) during the measurements of creatinine- clearance. Similar results followed the injection of xylose or glucose. To guard against possible glucose-contamination in the sample of xylose, the urine was shaken for a few minutes with an equal quantity of a 20 per cent suspension of washed yeast in distilled water and centri- fuged. Blanks, with only the yeast-centrifugate, were non-reducing. The glucose was given in high concentration ( cc. 70 per cent per 40 grams) because the tissues tended to remove it from the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
