URINE.

Infirmary, in which the quantity of urine voided daily amounted 

 to 45 Ibs., while its specific gravity was 1-054. The quantity of 

 sugar which it contains increases with the specific gravity. The 

 following table, drawn up by Dr Henry,* from his own experi- 

 ments, show the quantity of solid matter contained in diabetes 

 urine of different specific gravities. 



In this disease the thirst is insatiable, and the appetite vora- 

 cious. Yet the egesta in general are less than the ingesta. The 

 following two cases, which illustrate this, are related by Mr 

 Macgregor in his Experimental Enquiry. 



1. A boy, 16 years of age, weighing 5 stones and 2 Ibs. 

 Specific gravity of urine 1-035. The following table shows the 

 ingesta and egesta from the 6th December to the 31st December 

 inclusive :
