34 Notes from the Physiological Laboratory 



A NOTE ON THE BEHAVIOR OF HYDROBRO- 

 MIC ACID AND OF POTASSIUM IODIDE IN 

 THE DIGESTIVE TRACT. 1 



I VENTURE to present before the Society a brief 

 note upon a subject not strictly neurological, but 

 having direct bearing upon the relations entertained 

 to the processes of digestion by two drugs, which 

 are of interest to the neurologist. 



In a series of artificial digestions, in which hy- 

 drobromic acid was present in the digestive mixture 

 in amount corresponding to the therapeutic dose, I 

 have noted, 



(a) That salivary digestion was completely sus- 

 pended, whereas 



(6) The peptonization of proteid food-stuffs was 



1 The general deductions herein made from the study of 

 these two drugs are applicable respectively to all acid and 

 alkaline drugs given by the mouth, and a more descriptive 

 title of the paper would have been " Time Relations in the 

 Exhibition of Acids and of Alkalies."
