Miles Hopkins and George I. Warner. And the ardor of Dr. Mitchill’s zeal is 
illustrated in his description of the object of the association, which he said “was 
to arm every hand with a hammer, and every eye with a microscope.” The 
Medical Repository, from 1803 to 1809, and the Transactions of the Society for 
the Promotion of Useful Arts, from 1793 until 1804, contained many papers which 
contributed to excite the general interest now manifested in the study of the sci- 
ence. Among these we may specify a “Memoir of the Onondaga Salt Springs, 
and Manufactures in the State of New-York, by Benjamin De Witt ;” “ Obser- 
vations on the Natural History of Kinderhook and its immediate vicinity, by 
David Warden,” in 1803; “ Mineralogical Description of the Wallkill and Sha- 
wangunk Mountains in New-York,” by Samuel Akerly; “Descriptions of Fluate 
of Lime and Oxyde of Manganese in the State of New-York,” in 1808; and 
“ Mineralogical Notices of Onondaga, New-York,” 1809. But the effort which 
proved most successful in this department, was the establishment of the Ameri- 
can Mineralogical Journal in 1810, conducted by Archibald Bruce. This work 
was continued until 1814, and was enriched by the learned investigations of 
Mitchill, Bruce, Akerly, Chilton, John Griscom, Benjamin Silliman, David R. 
Arnell and others. 
An address by T. Romeyn Beck, before “ The Society for the Promotion of 
Useful Arts,” on the mineralogical resources of the United States, published in 
1813, exhibited a very full view of the mineral productions within the state 
known at that time. Professor Cleveland’s elementary treatise on mineralogy 
and geology, published in 1816, is still a standard work. Dr. Mitchill, in 1818, 
published a reprint of Phillips’ elementary introduction to mineralogy, with notes. 
Professor Siliman, in the same year, established the “American Journal of 
Science,” which most useful periodical is still continued. Mineralogy has always 
held a prominent place in that journal, and it contains many valuable papers, 
showing the progress of the science in this state. The Lyceum of Natural His- 
tory, established in New-York in 1818, and a similar institution founded at 
Albany, contain rich collections of minerals. The latter, through the liberality
