It is a remarkable fact that in such a well systematized science as medicine, so perfectly obvious a fact as micturition has escaped a clear-cut definition of its various phenomena. The looseness of the terminology has engendered looseness of diagnosis and therapy. We are, therefore, daily encountering essays in our medical literature dealing with incontinence of urine which mean principally excessive frequency of urination. I was as much a sinner as the rest, as may be seen by one of my previous articles,1 in which I reported sixty-four cases of pollakiuria under the false title of polyuria.
DEFINING THE SUBJECT
