Per-acid, and especially super-acid urines deposit urates as they cool—even sometimes this will happen at the moment they are discharged into a cold vessel. A urine may, however, be per-acid, or even super-acid, though remaining transparent in the cold. The observer should bear in mind, that the urine voided before breakfast, is generally more acid than that passed at other times. The sense of smell sometimes suggests the presence of an excess of acid. Inasmuch as the higher ranges of the acidity of the urine are, in all probability, 1 In these cases, just as the reaction alternates from decided acidity to alkalinity, so the nature of the deposits varies: the acid samples becoming turbid from amorphous urates, and letting fall crystals of uric acid, while the alkaline ones are milky from earthy phosphates.
