The murexid test for uric acid and the urates is one of greatbeauty. Place some of the sediment in a porcelain dish, add adrop or two of nitric acid, and carefully evaporate almost to dry-ness. Add a few drops of ammonia; or, better still (Earp) in-vert the dish over another in which a dry ammonium salt is vola-tilized. If uric acid is present, a beautiful purple color willappear. Coloring Matters.—Our unsatisfactory knowledge of thesesubstances and their clinical significance is to be regretted, sincesome of them possess an importance next to albumin and s
