CHAPTER VII. 
ANALYSIS OF THE FOUR PRINCIPLES (CONTINUED). 
I. THE METHODS OF THE ENVIRONAL MODE OF EACH PRINCIPLE, WITH THE ForMS 
OF EACH METHOD. 
Producing demarcation of habitudinal Producing intensification of habitudinal 
groups: groups: 
Environal partition. Environal election. 
Endonomic partition. Endonomic election. 
Industrial partition. Habitudinal election. 
Migrational partition. Aptitudinal election. 
Heteronomic partition. Heteronomic election. 
Transportational partition. Natural election. 
Geological partition. Artificial election. 
Artificial partition. 
Producing demarcation of racial Producing intensification of racial 
groups: groups: 
Environal isolation. Environal selection. 
Endonomic isolation. Endonomic selection. 
Industrial isolation. Habitudinal selection. 
Chronal isolation. Aptitudinal selection. 
Seasonal isolation. Heteronomic selection. 
Cyclical isolation. Natural selection. 
Migrational isolation. Artificial selection. 
Heteronomic isolation. 
Transportational isolation. 
Geological isolation. 
Fertilizational isclation. 
Artificial isolation. 
Having completed our analysis of the methods and forms of the 
reflexive mode of influence, we will now briefly survey the forms of the 
environal mode. Under each or the four principles, when we find that 
the relations between the group and its environment are determined 
by conditions within the group, we call the influence endonomic selec- 
tion, election, isolation, or partition, as the case may be; or if the 
relations are determined chiefly by conditions lying outside of the 
group, we then speak of the influence as heteronomic. 
1. Environal Selection and Environal Election. 
Environal selection, as we have just seen, may be either endonomic 
or heteronomic. 
Divergent forms of endonomic selection often arise through divergent 
habitudes or aptitudes of the individuals starting the isolated colonies, or 
through the accidents attending the entrance of small groups into isolated
