value will be obtained. This ratio was found by Minkowski to be 

 between 2'61 and 2*94 in observations on three starved depancreated 

 dogs of different sizes. Practically the same ratio is found when 

 flesh alone or any other form of proteid food (plasmon, casein, 

 &c.) is given, the average ratio for a large number of observa- 

 tions being 3:1, and varying between 2*62 and 3 '05 : 1. 



Where traces of pancreatic tissue are left, as was the case 

 in an experiment conducted by Cobb and the author, the glycosuria 

 is not so marked and almost disappears if no food be given. 

 As the results of this observation show some interesting points, 

 which we will have occasion to refer to later, we give them here 

 in tabular form.

When, however, carbohydrates are included in the diet the 

 sugar excretion is raised, but not that of the nitrogen indeed by 

 their proteid- sparing influence these food-stuffs may cause the
