Summarising we arrive at the following conclusions : 
1. The number of cases of replacement of substituents in the 
compounds C,H,AB and C,H,ABC quoted in the literature is small 
in comparison = the mance of possible cases. 
2. The data of the literature are of little value for a systematic 
research as to the substitution problem as they have rarely been 
obtained under comparable conditions. 
3. From the study of the replacement of chlorine in the three 
dichlorobenzenes, the three chloronitrobenzenes and the six nitro- 
dichlorobenzenes by OCH, and N(C,H,), it is shown:
