for the presence of this tellurium and of selenium, so far as can be 

 ascertained by tests for known elements, and when it is further 

 considered that Staudenmaier's results are the same as Brauner's, 

 though obtained by a wholly different method, no reasonable doubt 

 can remain that the atomic weight of tellurium is 127*6. 



The occurrence of tellurium in Japan in association with sele- 

 nium in native sulphur is also a fact of great significance in settling 

 the place of this substance in a natural classification of the elements, 

 showino-, as this does, so close a habitude to exist between it and 

 sulphur and selenium.
