The following lines become doublets, but they have not the 

 same general appearance. The two constituents of several of 

 them are equally strong in both edges ; whilst, of others, the 

 inside edges are sharper and stronger than the outside edges, which 

 appear to be more diffuse. It is probable that other constituents 

 overlap — but they are too weak and diffuse to separate distinctly 

 by the calcite. The measurements were taken between the 

 centres of these aggregates. The values of dX/X 2 for the con- 

 stituents of 3690"3 and 2372*2 appear to be identical with those of 

 the strong constituents of the quadruplet from 34604 (p. 326).
