Na. The first seven doublets were allocated by RYDBERO, using the measurement* 

 by ANGSTROM, THALEN, and LIVEING and DEWAR. They were, also so given by 

 K. and R. The remainder were given by ZKJKENDRAHT. The actual measures 

 given in the list are by the observers indicated by the letters. 



K. Both RYDBERG and KAYSER and RUNGE interchanged the S and D series, 

 allocating those in the list to the S series. This was first corrected by Rm.* The 

 mistake is repeated in KAYSER'S ' Spectroscopie,' Bd. V. The line 6938 "8 covers both 

 KD 2 (3) and KS t (2). The pair at 4871 were first observed by L.D., but the more 

 recent measurements by S. are inserted. 



Rb. RL. refers to RANDALL, RE. to RAMAGE. The lines 3-6 were allocated by 

 RYDBERG, and by K.R. The first doublet was observed and allocated by RANDALL. 

 The second doublet has raised the question of whether Rb possesses satellites. The line 

 7757 has only been observed by SAUNDERS, who allocates it to RbD u (3), with 7759'5 as
