Of nine cases of diabetes, eight of which have been admitted into the Royal Infirmary during the last seven months, and in which the specific gravity of the urine was determined, I found it to range between 1.03J and 1.055, and the average density will be seen from the following table : No- Name.

Healthy urine of density 1.029 contains 68 parts of solid matter in 1000 parts. Diabetic urine, however, contains a much great- er proportion of solid constituents.
