characters which the advanced state of the science to which it is devot- 
ed may seem to require. I may also observe, that the annexed table 
contains the names of those minerals only which have been found by 
myself, or published as New- York minerals, by others. Several doubt- 
ful ones collected during the progress of the survey, still remain to be 
examined; and when they have been, it is probable that the catalogue 
will be somewhat enlarged. I need scarcely say that I invite the at- 
tention of those who are engaged in similar pursuits to the general out- 
line here presented, and solicit their aid in the completion of the work.* 
Tabular View of the Minerals of the State of New-York. 
CLASS I. 
Gaseous Minerals. 
Usually held in solution by water under pressure; bid given out when the 
pressure is relieved. 
1. Combustible Gases. 
Those which burn upon the application of a lighted taper. 
Hydrogen gas. Carburetted hydrogen gas. Sulphuretted hydrogen gas. 
2. JVon-combustihle Gases. 
Those which do not bum. 
Oxygen gas. Nitrogen gas. Carbonic acid gas. 
CLASS 11. 
Combustible Minerals, not gaseous. 
Solid or liquid bodies which burn with ordinary degrees of heat. 
Anthracite. Coal. Lignite. Peat. 
Graphite. Bitumen. Sulphur. Amber, 
CLASS m. 
Uncombined Acids, not gaseocts. 
Sulphuric acid. 
CLASS IV. 
Alkaline Minerals. 
Composed of one or more of the common alkalies^ ammonia^ potashj ot' 
soda^ and usually containing an acid. 
1. Ammonia. 
Carbonate of ammonia. 
* My principal object in publishing this tabular view, at the present time, is, that I may pro= 
fit by remarks and criticisms upon the proposed arrangement, and be apprized of any omissions 
in the catalogue of our minerals.
