the most active mouse was the most dominant one and the least active 

 one the most subordinate. 



It can readily be shown that with N's as large as eleven, the number of 

 contacts, ric, is so nearly proportional to velocity, v, as to justify utilizing 

 number of contacts as a measure of velocity in the present example. From 

 Eq. (91) it is seen that S^i'''> varies inversely with Vi, and therefore on a 

 theoretical basis mice with few contacts should be those wdth large response- 

 evoking capacities.

Where v represents relative velocity as calculated by Eq. (108) for any 

 A^, empirical calculation will show that: 



Then where wj°^^) and 7ilf-p^ represent respectively, observed and ex-
