* Our numbers bere differ by about 2 tenth-metres, but an iron line in this part of tbe spectrum has 
given the following wave-lengths, 3358‘7 (H. and A.) and 3359'2 (Cornit). 
f Messrs. Livecng and Dewar give 2852 - 0 for this line. (“ On the Disappearance of some Spectral 
Lines,” Proc. Roy. Soc., vol. xxxiii., p. 429.)
