Relative ƒ-VALUES for Lines of TI II.

The relative f-values for 63 lines in 17 multiplets of Tin in the wave-length range XX 3143-3761 have been measured. The method was essentially that described in Mt. W. Conir. Nos. 528 and 581, with the exception that a high-pressure mercury arc was used as the source of the continuous spectrum, thus enabling furnace absorption lines to be observed at temperatures up to 30000 C
