[ainslie-fuller] ultra-violet OF CERTAIN METALS 69 



Zinc. 



The vacuum arc spectrum of zinc was obtained by putting zinc 

 in iron terminals in the arc lamp. The current used was 6 amperes 

 which gave a fairly continuous and intense arc. The lines obtained 

 do not agree with the values given by Handke^ for a zinc spark.

* These two lines may be due to cadmium but they appear to be zinc.
