Normal urine is of a clear amlier or citron-yellow color, a 
brackish tnste, a peculiar odor, a faintly acid reaction, and 
a specific gravity ranging from 1.016 to 1.025. Within the 
limits of health, however, it varies greatly in color, reac- 
tion, and density, according to the age, occupation, and diet 
of the individual, the time of day, and the season of the 
year. That passed In the morning upon rising is usually 
chosen for analysis, as presenting the average characteris- 
tics of the entire quantity excreted during the twenty-four 
hours. The average amount passed during this period is 
estimated at between three and four pints. The propor- 
tion of solid matters contained in every hundred parts of 
urine varies from three to seven parts or more, from 45 
to 55 per cent, of which is urea, the rest being chlorid of 
sodium, phosphates, sulphates,. ammonia, extractive mat- 
ters, and uric acid. The chemical analysis of the urine 
and the microscopical examination of Its sediment are Im- 
portant aids in the diagnosis and prognosis of many dis- 
eases. After its excretion in the cortical part of the kid- 
ney the urine passes at once through the ureters to the 
bladder, where it Is held for a period and voided through 
the urethra at the will of the individual.
