In several of my excursions I was accompanied, and much as- 
sisted, by Messrs. William R. Guest and William P. Wainwrightof 
this city, members of the chemical department of the University. 
Should the plan meet your approbation, I intend, during the 
next season, to complete the examination of the ores which have 
formed the principal subject of the present report, and to com- 
mence that of our mineral waters, including the salines; and hope 
to be able, in my next annual communication, to lay before you a 
general view of these important mineral productions. 
I have the honor to be, 
With great respect, 
Your obed't servH,
