“The collections of the Greological Survey contain a series of rocks col- 
lected in Trans-Pecos Texas by Prof, von iStreeruwitz on his travels for 
exploration of the ore deposits during the last three years. It has not 
been possible during my short stay in the Ceological iSurvey to work up 
a detailed investigation of that miaterial, but only to give a brief pre- 
liminary report, partly because the thin sections for mieroiscopieal exam- 
ination of all specimens could not be gotten ready, partly because no chem- 
ical tests or analyses have been made of the rocks or their constituents. 
Besides, there are wanting special notes in regard to the occurrence of 
these rocks in the field. Everybody familiar with the progress of Petrog- 
raphy during the last years knows that besides the mieroscopical investi- 
gation on the one hand, the chemical in the laboratory, and the geological
