III MINERALOGY AND GEOLOGY. 
1. Husynchite and Dechenite—In an extended investigation on Vana- 
dium, C. Czupnowicz reviews the analyses of vanadinite, dechenite, ara- 
oxene and eusynchite. He shows, that the method used by Tschermak

stated that, on qualitative analysis of this mineral, I had found it to 
contain zinc, and attention was also called to its remarkable resemblance 
to dechenite. This statement is now confirmed by the analyses of Caud- 
e 
now 
also the fact that in the same article I pointed out the existence of zine 
in dechenite, and suggested the probability that dechenite and areoxene 
were identical. About the time my note was published, Bergemann gave 
the following analysis of arseoxene in Leonhard and Bronn’s Jahrbuch 
fir Mineralogie (1857, p. 397):

Bergemann mentions that arzoxene enite occur together at 
neutral vanadate of lead. I have examined a specimen of 
obtained from Dr. Krantz in 1851, shortly after Krantz and Bergemat 
had described this species, and have found that it contains, not only pei 
but arsenic, The specimen has the appearance of being pure and vidal 
tered; it is perfectly homogeneous, has a brownish-red color, is ne
