NOTE OX A NEW ELEMENT ALLIED TO MOLYBDENUM. lö 



from the higher oxide, resemble the corresponding molybdates, 

 but the mercurous salt consists of golden yellow crystals. 



4. The hydrated lower oxide (?) has a graphitic appearance 

 and is insoluble in hot, dilute hydrochloric acid. 



5. On heating in a current of hydrogen gas, either of the 

 oxides produces the metal, which is non-fusible at a red heat. 

 It burns brilliantly in the air, producing the higher oxide. 



6. The equivalent weight of the metal is somewhat above 

 that of molybdenum, being about 16.7. 



7. In producing a brown sulphide and in other respects, 

 above referred to, the new element resembles molybdenum, but is 

 distinguished from the latter in producing no colour reactions, 

 when a soluble salt of its higher oxide is reduced with zinc and 

 hydrochloric acid, either in the presence or absence of potassium 

 thiocyanate, and also by the fact that the metal dissolves in 

 hot, concentrated hydrochloric acid. 



8. The " new tin-grouj) element ", recently described by 

 Miss Evans is probably identical with the element, forming 

 the subject of this paper. 



9. A new rich source of nipponium has been discovered 

 and, incidentally, described. 



10. Besides nipponium and the new element now under 

 consideration, thorianite appears to contain still another new 

 element, the oxide of which is radioactive and dissolves in nitric 

 acid to form a bluish green solution.
