Mancanesze. (Plate XV.) 
Spectra 1, 2, 3, and 4 show the lines of the metal, one strong, 
and two dilute solutions. The spectrum given by the metal is 
practically identical with that of a strong solution. The three w 
lines in the region of gold line No. 24 form a very characteristic 
group, by which this element can be rapidly identified. The 
general results are as follows :-—
