water by stomach. The diuresis that follows infusion is delayed, 

 less intense, and greatly prolonged ; thus diuresis is not apparent 

 for six hours, during which oliguria prevails (D). Even with 

 smaller administrations (1.9 and 4.1% of Bo, B and C) seven hours 

 are required to eliminate in urine the entire volumes injected. At 

 any one load, the rates are all lower than when the water is given 

 by stomach. But 15% (Chiray et al., '38) to 21% (Falck) may be 

 tolerated when given by vein.

Water Load 



Fig. 33. Eate of urinary water output ( % of Bo/liour) in relation to sensible water 

 load (% of Bo). Single equal volumes of water are administered by five types of pro- 

 cedure. Same data of Hashimoto as in figure 32. 



Hashimoto ('14) injected water by vein in less amount (1% of 

 Bo). When given during a period of time equivalent to Falck 's 

 (0.1 to 0.2 hour) only oliguria results (C, figs. 32 and 33). But 

 given during 1.0 to 1.2 hour (E) some diuresis occurs, yet only 

 sufficient to return as urine during it one-fifth of the fluid adminis- 

 tered. 



Water given subcutaneously in the amount of 1% of Bo yields 

 no diuresis whether injected rapidly (B) or slowly (D, fig. 32). 



When water is given by rectum (3.6% of Bo, tests A in figs. 30 

 and 31) diuresis is prompt, but less in rate and less prolonged than 

 after the same load is given by stomach.
