in the zero-line the mean of the two values was taken. 

 The observed and calculated values of the maxima are given 

 in Table IV., in which the first maximum of Case I. 

 (-4970 cm. in the photograph) is equalised to the corre- 

 sponding calculated value 45, and all the other maxima of this 

 and the other photographs are altered in the same proportion.
