Art. XXXII. — On the Double Halides of Tellurium with 

 Potassium, Rubidium and Cmium • by H. L. Wheeler. 



The existence of double halides of tellurium with potas- 

 sium, sodium and ammonium was first indicated by Berzelius.* 

 He described the methods by which he obtained them, but 

 gave no analyses of the compounds. Later, Rammelsbergf 

 investigated the double chlorides of tellurium with potassium 

 and ammonium, with the object of determining their compo- 

 sition. He arrived at the formula 8KC1 . 3TeCl 4 and 8NH 4 C1.
