ATOMIC WEIGHTS 



463 



Mean, 50.395, ± .0015 



Hence Pd = 106.66. 



The atomic weight determinations by Krell, Woernle and Haas were 

 all made in the laboratory of Professor Gutbier at Erlangen. Krell " 

 reduced palladiammonium (palladosamine) chloride in hydrogen, and 

 afterwards heated the reduced metal in a stream of carbon dioxide. 

 His figures, with vacuum weights, are subjoined : 



Mean, 50.3945, ±. .0050 



Hence Pd = 106.65. The first, aberrant determination in the series, 

 is rejected by Ivrell. 



Woernle* also made analyses of palladiammonium chloride. The first 

 two reductions were effected in hydrogen, the other determinations were 

 electrolytic. His figures, with vacuum weights, are as follows :
