Retention capability of kidney for saccharose. 

 Experiments of September 17—23 1918. 



Experiment 37 (Sept. 26). 



The perfusion liquid contains 0,15"/,, maltose. 



0.1 c c. perfusion liquid: reduction 0,095 '/q. 



0,1 c c. urine of right kidney: reduction 0,105%. 



0,1 CO. urine of left kidney: reduction O,!!"/,,. 



Retained by each kidney: nothing. 



Experiment 38 (Sept. i26). 



The same perfusion liquid as in exp. 37. 



0,1 c.c. urine of right kidney: reduction O.l'Vo- 



0,1 c.c. urine of left kidney : reduction 0,105"/,, 



Retained by each kidney : nothing. 



Experiment 39 (Sept. 26). 



The same perfusion liquid as in exps. 37 and 38. 

 0,1 c c urine of right kidney: reduction 0,0625"/,). 

 0,1 c.c. urine of left kidney: reduction 0,0625%. 

 Retained by each kidney : 0,095—0,0625 = 0,0325'Vo. 



Experiment 40 (Sept. 27). 



0,1 c c. perfusion liquid : reduction 0,08%,. 



0,1 c.c. urine of right kidney: reduction 0,065"/(,. 



0,1 c.c. urine of left kidney: reduction 0,0n25"/(i- 



Retained by right kidney : 0,08—0,065 = 0,0150/ „. 



Retained by left kidney : 0,08—0,0625 = 0,0157" /o- 



It is clear from all the.se e.v iierimeiits that the quantity of maltose 

 retained is in any case ed-tremely small, notwithstanding the fact that
