These cal-culi are frequently found in menleading catheter lives who are notover-cleanly in the care of theircatheters. Albumin.—A generation agoit was the medical belief of the day that albuminuria was a dangerous symp-tom, generally indicating organic disease of the kidney of a serious natureand warranting the gravest prognosis. To-day we know it to be true thatalbuminuria is not necessarily a symptom of gravity, and that it often exists,especially in persons beyond middle life, with no other indication of renaldisease than, perhaps, a few hyaline or fine granular casts—so few as to beoften hard to find. In fact, so much has been written on this subject of late that the present- 1 See the writers paper on Phosphaturia, Boston Med. and Surg. Journ., Feb.

Whether or not therebe a physiological albuminuria, it is not in the province of this treatise todiscuss. The line between health and disease is not an easy one to find, andthe term physiological might prove hard to define in this connection. Atall events, albumin in the urine, if it means nothing else, means that theutmost watchfulness and care should be used before deciding that it has noclinical significance. In testing the urine for the presence of albumin we are fortunate in havingtwo tests, the heat and nitric-a
