The questions of special interest in connection with the prep- 
arations under discussion are the following: (1) How does 
the amount of sulphides produced in relation to the amount of 
sulphur used compare with the same relations in experiments 
1—a, 1—b, etc.? (2) What is the relative efficiency in respect to 
sulphides produced in preparations 15-15 as compared with 
preparations 16-18? We can obtain assistance in answering 
these questions by arranging our data in the following manner:
