THE STRUCTURE OF THE NUCLEUS. V 



As a rule, two values of dV/dt are entered for each temperature, one for a 

 moderate current of about .50 liter/min. through the condenser and the other for 

 the stronger current of about 1.0 liter/min. 



11. Discussion. — ^The data of these tables might be constructed without 

 further reduction in a graph where the abscissas are temperatures and the ordinates, 

 ds/dt, proportional to the radial currents. Two curves ai'e suggested, one for the 

 high, and another for the low xkAodiy, dV/dt ; but in view of the slightly different 

 values of dV/dt implied in each, it is better to reduce to two volume standards. 

 dV/dt=Ai> liter/min. and 1.00 liter/min. were selected as most nearly coincident 

 with the observations as a whole. The reduction was made compatibly with the 

 I'esults of my eai-lier i)aper, linearly from two values of dV/dt and ds/dt at each 

 temperature. This linear lelation is again incidentally shown in figure 5 at about 

 19°. The slopes of these lines vary with temperature. 



Table 4 contains the original data and the values needed in these reductions, 

 as will be seen at once. The 6th and 7th columns show the currents which obtain 

 when the volumes .45 and 1.00 liter pass through the condenser per minute. 

 Color data ai'e omitted as of minor interest. One may note in passing that the co- 

 efficients, d{ds/dt)/d{d V/dt) or ds/d V, also fall off to zero with the degree of 

 ionization, and that they in general increase with temperature. The last columns 

 of the tables contain i-esults independent of the arbitrary scale of the electrometer.
