CORRESPONDENCE. 
Sketch of Dr. Frenzel. In my mail of a few days ago I found 
the following letter from Dr. Beck of the Bergakademic of Freiberg 
Saxony. 
* ''To my sorrow I must send you sad news from Saxon Freiberg. 
Our old and loved D. Phil. Frenzel died on the 29th of August of a 
cancerous .tumor of the stomach. (Kresbartige Magenverhartung). He- 
was confined to his bed only eight days though he was weakened for 
a longer period. A few days before his death he became chief officer of 
the smelting office laboratory." * * "he left his family, a widow and 
two daughters, in comfortable circumstances."
