any value for the reason that sodic chloride will precipitate 
protalbumose but will not affect in the least the deuteroalbu- 
mose. The latter would pass into the filtrate from 3, and 
thus vitiate the results of the subsequent tests for pep-. 
tones. 
Reverting to the case under consideration, I will state that 
Ewald’s test breakfast was administered on six different 
occasions. The expressa obtained on March 27th were re- 
jected on account of a distinct odor of sulphuretted hydrogen, 
the presence of which would have vitiated Guenzburg’s re- 
action and the results of the estimation of total acidity. The 
patient admitted having eaten some eggs on the previous day 
which may have been not quite fresh. It has been urged by 
Vierordt * and others that Ewald’s trial meal left room for 
considerable error by putting the working capacity of the 
stomach to but a slight test. To meet any objections on that 
score, I added to the breakfast in Exp. VII and VIII the 
white of two hard boiled eggs. 
The results of the analysis were as follows: —
