In the following Table the numbers obtained in several sets of experiments are simi- 
larly compared with those calculated from equations of the same form. The sets of 
experiments here given are selected out of a large number equally accordant with theory, 
with a view to illustrate the variety of circumstances under which this reaction conforms 
to the law which has been enunciated. For the comparison of different sets of experi- 
ments, it will be convenient to describe each solution by stating its total volume in cubic 
centimetres, and how many millionths of a gramme of the several ingredients it con- 
tained in a cubic centimetre. The conditions of each set of experiments are enume- 
rated at the head of the columns which contain the intervals actually observed and those 
calculated from the theoretical equation. The value of a for each set of experiments is 
put at the head of the column which contains the calculated intervals.
