Urinprov

The kidneys are destined to secrete from the blood the fluid known by the name of urine, and which cannot remain in the blood without prejudice to the health. The constituent parts of this fluid are different according to the age of the individual, the season of the year, food, drink, and other circumstances; but in general the urine contains what is called salt of urine, a little common salt, some calcareous earth, and mucus. These substances, according to the circumstances, are dissolved in more or less water. The colour, smell, and taste of urine vary according to the proportion of these ingredients to the quantity of the water.

Taste..!? Jomen. Länge var det en standardmetod för att avgöra statusen på någons urin. Hur goda resultat man fick vet jag inte. Inte heller ifall det var lättare att komma in på läkarlinjen för 200 år sedan.
