    the reagent paper, the urine preserves its brightness, or any slight turbidity it pos- sessed prior to testing is not increased, the observer may safely infer it is free from albumin.1 Tlae Mettaods originally proposed. —In the former editions of this work I directed the test-papers to be dropped into the urine without dilution. But I no longer advise this mode of observation : because experience has shown that it is open to certain fallacies, which are apt to mislead the observer ; such, for example, as the not infrequent precipitation of urates in concentrated urines—a precipi- tation which often wonderfully resembles the albuminous one—and the mucin reac- tion. It is true that heat is a corrective —at any rate with the mercuric test- paper—but, having to resort to it fre- quently, and here and there merely to disprove the presence of albumin, is somewhat troublesome. Then again, cases have been met with in which, 1 In using the compound mercuric test-paper, the observer merely requires to drop one into the diluted urine. The reac- tion, however, does not appear quite so quickly as when the acid and the reagent test-papers are applied separately.
