28. Remarks on the tables. Considering the graph, figure 10, correspond- 

 ing to table 14, it is seen that the curve as a whole lies above the locus n' 20os 3 . 

 This might be rectified by using a larger value of 5 than the small one (5 = 4.8, 

 while the mean value is 5.6) specially computed. The divergence of the 5- 

 effect is enhanced in view of the large number of exhaustions. 



The graph n = n Nn brings out for the first time the cycle of the first color 

 series, w y to w p, which in the shorter apparatus above was not fully attain- 

 able. The successive colors of the first annuli vary in the order of wave length, 

 though nothing was observed above the first w y. The next color cycle (en- 

 larged lo-fold in the adjoining curve) is very complete, though irregular from 

 the inevitable color distortion, the interval between observations being but one 

 minute. The following color cycles III and IV, which include the vivid annuli,
