19. Graphs for nucleation. The results for mono-chromatic light are 

 constructed in the chart, figure 6, and show the three prominent cycles with 

 suggestions of others crowded into the region of normal coronas ; but the latter 

 are uncertain. The two curves are more closely in agreement both in their 

 horizontal and vertical dimensions than was the case above. All four curves 

 agree, however, in their essential points, as closely as may be expected. The
