    Urine, in the normal state, is alwa)'s acid, and if it becomes neutral, it is only as Fustier has shown, be- fore a meal;* it presents also a variable color, due, you know, to a singular coloring matter, urobilin, which is derived like bilirubin, from the coloring matter of the blood corpuscles, haematin; finally it contains among its nitrogenized materials very important substances, urea f and uric acid, which are the waste products of the organic combustions of the economy. * Renee Jones has claimed that there exists a compensa- tory equilibrium between the acidity of the urine and that of the gastric juice. According to him, the urine is at its mini- mum of acidity at the time when the stomach is at its maxi- mum of acidity. Roberts has maintained that the urine becomes alkaline two or three hours after meals. Byasson aflSrms that the urine is least acid after the first meal, while the most acid urine is that of the night. Neubauer and Vogel have adopted Byasson’s view. Georges also holds that the alkaline reaction appears two hours after the meal. Delavand affirms, on the contrary, that the urine is acid during the entire day except in the morning, when it is generally neutral or alkaline. Finally, Fustier, who has made an important study of the reaction of urine, has shown that urine is always more ad 1 after meals, and that its maximum acidity is about four hours after dinner; urine, on the contrary, is always neutral or alkaline about eight or nine o’clock in the morning, or before the ingestion of any food. f Urea CH4 N’O was discovered in human urine by Rou- elle, in 1771, and obtained in a state of purity by Fourcroy and Vauquelin in 1779. ft is formed in the blond, eliminated by the kidneys and is found in the urine of all animals; it exists also in the amniotic fluid, the aqueous humor, vitreous humor,
