The importance of reliable and convenient methods of detecting the presence of albumen and sugar in the urine, as well as the quantitative estimation of each, must be recognized by every practicing physician as a diagnostic measure, and by every medical chemist as a means toward deciding that, at present, contested point—their presence or absence in physiological urine. As every reagent known has its sources of error, the question is not which is perfect, but which is least objectionable. As several new tests have been proposed for the detection of each of these substances in urine, and each of the reagents has supporters, who in turn consider each the most valuable, it seems desirable that some practical conclusion be reached. In this paper the more reliable of the older tests will be contrasted with the newer; and as the former have held the field so long, from their priority, if
