Dr. Mallet’s Analyses, &c. 18] 
Art. XX.—Results “of some Analyses made for the Geological 
Survey of the State of Alabama; by J. W. Matxet, Ph.D., 
Professor of Chemistry in University of Alabama. 
A LARGE number of analyses have been made of specimens 
collected by those in charge of the field-work of the Geological 
Survey of Alabama under the direction of Professor Tuomey, 
State Geologist, but the value of most of these is of a technical 
or agricultural character, and the results will appear most appro- 
priately in the Report upon the State Survey. It is intended 
in the present paper merely to extract a few analyses which 
Seem to possess a distinct scientific interest, and to notice very 
briefly their results. .
