PREVIOUS WORK 
During the last century comparatively little work was done on New 
York calcites, the interest of mineralogists being centered almost entirely 
upon one occurrence, that at Rossie, St Lawrence co. Cleaveland, writing 
in 1822, mentions seven New York localities for calcite, viz: Dutchess 
county, Catskill, Bethlehem, Diamond island and Rogers rock (Lake 
George), Ticonderoga, and Niagara Falls. His notes on these localities are 
limited to such crystallographic identification as could be made by the 
unaided eye and, with the exception of the Niagara Falls locality where he 
identified the cuboid of Haty (—3R), may be passed without comment. 
In 1825 Robinson, in his Catalogue of American Mineral Localities, notes 25 
localities for calcite in New York. His notes, however, contain little infor- 
mation as to the occurring crystal forms other than that previously given 
by Cleaveland. 
C. U. Shepard, in the first volume of his treatise published in 1835, 
illustrates a calcite crystal from Leyden, Lewis co. This is the common 
prismatic habit terminated by —$R. 
J. D. Dana, in the first edition of his System of Mineralogy (1837), illus- 
trates a combination from Rossie showing the common forms R3 and R. 
He also mentions in the text the localities at Oxbow, St Lawrence co. and 
Lockport, Niagara co. The latter locality was previously mentioned in 
Robinson’s list. . . 
In 1842 Dr L. C. Beck published his Mzneralogy of New York in which 
14 pages are devoted to calcite localities and 45 figures in the text illustrate 
the simpler crystallographic combinations. The following forms are shown 
singly or in combination: »R, 16R(?), 4R, R, OR, —}R, —{R(?), —2R, 
—5R, $R3 and R38. Of the 33 localities mentioned by Beck those at 
Tompkins Cove, Rockland co. and Rossie, St Lawrence co. are described at 
length and the crystals figured in detail. The calcite crystals from 
Rossie are illustrated in five figures showing combinations of the forms 
OR, R and R3, twinned parallel to OR, the twinned crystal being shown in
