366 C. U. Shepard on Meteoric Iron from Cayuga Co., N.Y. 
stance, which is also insoluble, and which has been called Schrei- 
bersite by Patera; though this designation cannot be maintained, 
inasmuch as I had previously called another meteoric mineral by 
this name. 
I propose the name of Partschite for the substance now under 
consideration, in honor of the eminent Prof. Paul Partsch of Vi- 
enna, whose contributions to astrolithology in the description of 
the meteoric collection of the Imperial Museum at Vienna, have 
been so important to: the progress of this interesting branch 
knowledge.
