Miles Hopkins and George I. Warner. And the ardor of Dr. MitchiU'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 

 ]\Iedical 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 Walkill and Sha- 

 wangunk Mountains in New- York," by Samuel Akerly ; " Descrijitions 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 Grlscom, Benjamin Silliman, David R. 

 Arnell and others. 



An address by T. Romeyn Beck, before " The Society for the Promotion of 

 Useful Arts," on the inineralogical resources of the United States, published in 

 1813, exhibited a very full \'iew of the mineral productions within the state 

 known at that time. Professor Cleveland's elementary treatise on mineralogy 

 and geologj', published in 1816, is still a standard work. Dr. Mitchill, in 1818, 

 pubhshed a reprint of Phillips' elementary introduction to mineralogy, with notes. 

 Professor Silliman, 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
