Klatzo's' figures are as follows, with the tliii'd column added by the 

 writer : 



GIO. BaSO^. Ratio. 



.2339 2.1520 920.052 



.1910 1.7556 919.162 



.2673 2.4872 930.490 



.3.585 3.3115 923.710 



.2800 2.5842 922.929 



Mean, 923.268, ± 1.346 



Hence Gl = 9.283. 



Combining these series into a general mean, we have — 



Awdejew 921.316, ± 1.577 



Weeren 923.834, ± 1.303 



Klatzo 923.268, ± 1.346 



General mean 922.977, ± 0.805 



Debray'' analyzed a double oxalate of glneinnm and ammonium, 

 GlClSTHJoC^Os. In this the ghicina was estimated by calcination, after 

 first converting the salt into nitrate. The following percentages were 



found : 



11.5 

 11.2 

 11.6 



Mean, 11.433, ± .081 



The carbon was estimated by an organic combustion. I give the 

 weights, and put in a third column the percentages of COo thus obtained : 



Salt.

Hence, from the ratio between 4C0o and GIO, Gl = 9.3375. 



In 1880 the careful determinations of Nilson and Pettersson appeared." 

 Tliese chemists first attempted to work with the sublimed chloride of 

 glucinum, Ijut abandoned the method upon finding the compound to
