544 The Urinometer originally suggested by Dr. Prout for ascertaining the density 

 of urine has a scale divided into 60 degrees, the zero being the point at which the 

 instrument floats in distilled water at a temperature of 60 Fahrenheit. 



The numbers on the scale added to 1,000 (the assumed specific gravity of water) 

 give the specific gravities at the respective points. If the number cut by the sur- 

 face of the fluid under test be 30, it indicates a specific gravity of T030. On the 

 reverse side of this scale will be found the letter W at the top, on the same line as 

 the indicating water. Lower down the scale is a space marked H, signifying 

 healthy standard, which ranges from 10 to 20 of the scale. The space from 30 to 

 60 is marked diabetes, the urine of diabetic patients generally ranging between these 

 points. See figs. 444 and 444*.
