* Components about 0155 apart on photographic plates. (J.) 



t Another set of measurements on photographic plates ffives the components 

 as 0-083 apart. & F 



f Components about 0-088 apart on photographic plate. It is an exceed- 

 ingly difficult double and it is possible that this doubleness of E 2 is really a case 

 of the reversal of line in the Sun. (J.) 



§ Components 0-077 apart as determined by another short series (R.) ; 0-130 

 on photographic plates (J.). 



|| . Components of double about 0075 apart on photographic plates. The fine 

 side line to red is about O'llO from the red component of double. (J.)
