Urine to be collected punctually every two hours and kept in the
ice-box, every specimen having twenty drops of tutuol added to insure
preservation.

Another ~modification of the Hedinger-Schlayer diet~ is used in the
~Peter Bent Brigham Hospital~,[131] Boston, Massachusetts, as follows:

7 A.M. Coffee, milk, sugar, toast, and butter.

10 A.M. Milk, toast, and butter.

12:30 P.M. Bouillon, broiled steak, butter, mashed potatoes, toast,
coffee, milk, sugar.

4 P.M. Tea, milk, sugar, crackers.

7 P.M. Soft egg, blanc-mange (1 egg, sugar, cornstarch, and milk)
and cream. Amounts sufficient to give 2500 calories, 1500
c.c. fluid, 76 grams of protein, 127 grams of fat, 245
grams of carbohydrate, and from 5 to 8 grams of sodium
chloride.

On two days previous to the test the patient usually had a diet
containing 2000 calories, 75 grams of protein, 4 grams of sodium
chloride.

The test diet is a mixed diet containing known amounts of water,
nitrogen, and chloride, together with the food diuretics (purins,
salt, and water), as can be seen. The diet is divided into unequal
portions containing known but varying amounts of fluid, nitrogen, and
salt. Two-hour specimens are collected from 7 A.M. to 9 P.M., and one
night specimen is obtained containing all the urine passed between 9
P.M. and 7 A.M. Each specimen is analyzed for volume, specific
gravity, total nitrogen, nitrogen concentration, total chloride, and
chloride concentration.

~Purpose of Tests.~--The purpose of the test is to find out to what
extent and in what manner the diseased kidney under stimulation by the
various diuretics taken in the food reacts in putting out the vary
