Signs given by the density of the composition and turbidity of urine

When the watery urine of persistent fever turns thick and there are good signs, it indicates a crisis by perspiration; if there are no good signs, and the fever is very burning, this indicates a burning in the heart or in the liver. The transparency of thick urine before a crisis is not a good sign, because it indicates that matter is locked up and nature is unable to expel it.

Thick, cloudy urine, which does not give any sediment and does not brighten, is a sign of boiling juices due to the significance of extraneous heat and the weakness of the innate heat that causes ripening; therefore such urine is not good. Thick urine, especially on the fourth day, often resolves fevers from exhaustion, especially if this is accompanied by bleeding from the nose.
