| Description | The authors refer to the researches of Andrews, Clark, Neubauer and Vogel, and others on the presence of ammonia as a constant constituent of healthy urine, Neubauer regarding 10.8 grains per diem as the average normal excretion. After numerous experiments, the authors regard this quantity as excessive, and suggest some reasons for this discrepancy. The method adopted by the authors is as follows: the freshly passed urine is to be first diluted with a given bulk of distilled water, sufficient to destroy all apparent colour, a known quantity of the urine being taken in each case. To these is to be added an excess of Nessler’s solution, and then compared with the tint-depth produced by known quantities of ammonia in a similar bulk of liquid treated with the same solution. The trace of ammonia in the water itself must be always allowed for. The external temperature in the observations was always about 62°.
