    P 0 K THE 0 r E ]l A T I X G ROOM may be as high as 1.030, while a diabetic urine may have a specific gravity of 1.025 or less, in consequence of a large volume passed. The specific gravity of urine is determined by the use of a urinometer, which is a small hydrometer graded from zero or 1000 to 60 or 1060. As the temperature infiuences liquids as to their density, a urinometer can only give correct results at a certain temperature, which is generally marked upoii the instrument. 60 degrees F. 5* Ordinary Urinometer. In taking the specific gravity of urine, the quantity must be sufficient to float the instrument, and the vessel in which it is contained, wide enough so that it will not impinge upon its walls. After the instrument is in proper position and floating freely, stand with the back to the light, hold the vessel vertically at the height of the eye, and read off the number on the stem of the urinometer, in the plane at the lower sharply defined edge of the concave surface of the liquid.
