During the last few years much has been written on the subject of albuminuria without demonstrable disease of the kidneys. Most cases of this sort are properly "cyclic" albuminuria; the albumin is absent upon rising in the morning, appears after breakfast and is usually not present late in the day. It is not influenced by diet, and may even be absent after active exercise. Postural albuminuria is not inaptly applied to this condition. The majority of the cases in persons who are supposed to be in perfect health and in whom no organic disease can be found are discovered accidentally. In many instances life-insurance examinations are instrumental in disclosing the condition. The discussions as to the relation such albuminuria bears to life-expectancy are of little value, as they are based largely upon theories and the conclusions are drawn by men who are apt to give the favor of a doubt
