each to charge the nearest point of the resonator, so that the first 

 oscillation is produced between the diametrically opposite parts of 

 the circle. As, however, the electricity tends to oscillate in all 

 the amplitude of the circle, this takes then its normal period, and 

 the nodes are arranged along the wire. 



We have in the second place investigated how the plane of the 

 resonator must be turned about its vertical axis in order that the 

 total effect of the two " shocks " which excite the oscillation may 

 be as great as possible. 



These directions are indicated in fig. 1. They have for the 

 most part been determined where the maxima should be according 

 to the measurement of the nodes. Among other orientations 

 figured are two which have been taken in the nodes (dotted lines). 

 These directions of maximum effect pronounce strongly, it seems 

 to us, for a direct radiation from the end of the wire. 



Of the three series of observations made in the centre of the 

 loops it follows that the perpendicular to the circle is almost along 

 the bisectrix of the angle which the line going directly to the end 

 of the wire forms with the parallel to the conducting wire. The 

 two observations made in the nodes themselves show that to have 

 the maximum effect the circle must be orientated so that the 

 electrical undulations coming from the end of the wire arrive 

 perpendicularly to its plane, and that the action of the second 

 shock is by this fact annulled. 



The results which we have enunciated enable us to give a certain 

 development to the conception of the moving electrical tube devised 

 by some English men of science. Assume that the electrical tube 

 of the direct wave, which moves at each point at right angles to its

momentary direction, is almost rectilinear, and at right angles to 

 the conducting wire: this will no longer be the case with the 

 reflected wave.
