(iii.) Interference System. With the apparatus arranged 

 for observing the interference phenomena with this condenser, 

 three sets of readings were taken. One of these is shown in 

 Table IX. It will be seen to include readings for a resistance- 

 bridge also. This bridge consisted of graphite markings upon a
