In a more extended memoir, which includes tlie results of the last 

 mentioned investigation, Gutbier ^ gives a series of analyses of basic tel- 

 lurium nitrate, like those of Koethner. His figures are as follows, not 

 reduced to a vacuum standard: 



Mean, 83.439, it .0156 



Hence Te= 126.74. 



Gallo's ^ investigation was an attempt to determine the electrochemical 

 equivalent of tellurium in terms of silver. Silver and tellurium were 

 thrown down by the same current, but in different receptacles, and so 

 were directly compared. In the third column I give the ratio 4Ag: 

 Te::100:a;;
