This instrument isvery portable, can be quickly used at the bedside, re-quires only a very small quantity of urine, and givesmore accurate results than the common urinometer. 406 REFERENCE HANDBOOK OF THE MEDICAL SCIENCES. Urine. I line. For purposes of scientific investigation, the only proper•way to take the specific gravity is by the picnometer, orspecific gravity bottle, and balance (Fig. 4255, E and F),being careful to bring the urine to the temperature atwhich the picnometer was originally graduated, usually60° F. or 20° C.
