Moreover, as in these cases the volume of urine excreted after several injections was greatly diminished in amount, owing to partial suppression having occurred, the lower percentage of haemoglobinuria observed could not result from the secretion of a large quantity of watery urine dependent upon decreased absorption of water as it passed through the uriniferous tubules. 15 - /•?-• /J-- 11 -- 10-. 9 -? a-- 7- 6^ J-- ?..

The numbers along the curve representing the dejree of haemoglobinuria indicate the amount of urine passed. It would seem that these observations are more in harmony with the view that haemoglobin is secreted by the renal epithelium than that it is filtered through the glomeruli, and, that the amount of haemoglobin eliminated into the urine is dependent upon the activity of the epithelium lining the renal tubules. There is, moreover, additional evidence which affords support to this view, and that is obtained by examination of the epithelium lining the capsules and various portions of the uriniferous 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 Liverpool School of Tropical Medicine.
