88 A STUDY OF THE INFLUENCE 



drying a weighed quantity of fluid in a tared crucible at 

 100-105 C. Protocols follow: 



. 



A. Control Experiments with Water : 



I. 31 v, 1897. Dog, with gastric fistula, well healed. Weight 21 kilos. 

 Fluid removed completely through fistula. 



Introduced 200 c. c. distilled water at 10.60 A. M. 

 Contents removed at 1.56 p. M. = Sj^ hrs. 



Volume of fluid recovered from stomach = 160 c.c. = 80 per cent of 

 original volume. 



Analysis of the contents gave : 



Total acidity 0.203 per cent 



FreeHCl 0.192 



Loosely combined HC1 . . . 0.002 



Salts 0.009 



Total solids 0.624 



II. 28 vi, 1897. Dog, with gastric fistula, well healed. Weight 25 kilos. 

 Fluid removed completely through fistula. 



Introduced 136 c. c. distilled water at 11 A. M. 

 Contents removed at 1.45 p. M. = 2f hrs. 



Volume of fluid recovered from stomach = 110 c. c. = 81 per cent of 

 original volume. 



Analysis of the contents gave : 



Total acidity 0574 per cent 



FreeHCl 0.241 



Loosely combined HC1 . . . 0.018 



Salts 0.016 



Total solids 0.77 



III. 24 v, 1897. Dog. Weight 7.7 kilos. 



Introduced 125 c. c. distilled water at 10 A. M. 

 Contents removed at 1.60 p. M. = 3$ hours. 



Volume of fluid recovered from stomach = 114 c. c. = 91 per cent of 

 original volume. 



Analysis of the contents gave : 



Total acidity 0.094 per cent 



Free HC1 0.065 



Loosely combined HC1 . . 0.004 



Salts 0.026 



Total solids 0.47 



* Expressed as HC1 in all the experiments.
