VIII. 31 v, 1897. Dog. Weight 21 kilos. Gastric fistula well healed. 

 Contrast experiment with water and alcohol. 



a. The first part of this experiment has been described under L p. 88. 

 /}. After discharge of previous stomach contents completely through 

 fistula, 200 c. c. 37 per cent alcohol were introduced into the 

 stomach through fistula at 1.55 p. M. 



Contents removed at 6 P. M. = 3fa hrs. 



Volume of fluid recovered from stomach = 460 c. c. = 230 per cent 

 of original volume.* 



Analysis of the contents gave : 



Total acidity 0.220 per cent. 



FreeHCl 0.164 



Loosely combined HC1 . . 0.011 



Salts 0.045 



Total solids 0.987 



C. Experiments with weak (5 per cent) Ethyl Alcohol : 



IX. 24 vi, 1897. Bitch. Weight 8 kilos. 



Introduced 100 c. c. 5 per cent alcohol at 10.45 A. M. 

 Contents removed at 2 p. M. = 3^ hrs. 



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

 original volume. 



Analysis of the stomach contents gave : 



Total acidity 0.119 per cent. 



FreeHCl 0.086 



Loosely combined HC1 . . 0.011 



Salts 0.022 



Total solids 0.69 



X. 8 vi, 1897. Bitch. Weight 7.3 kilos. 



Introduced 110 c. c. 4.8 per cent alcohol at 9 A. M. 

 Contents removed at 12.45 p. M. = 3} hrs. 



Volume of fluid recovered from stomach = 135 c. c. = 123 per cent of 

 original volume. 



Analysis of the stomach contents gave : 



Total acidity 0.202 per cent. 



FreeHCl 0.148 



Loosely combined HC1 . . 0.021 

 Salts 0.033 



* A post-mortem examination showed that the stomach contents could be 

 completely discharged through the fistula by the method adopted.
