This cavern contains masses of calcareous spar, in the forms which are usual in such loca¬ 
lities. The specimens, however, are seldom so beautiful as those which are found in the 
caverns of the county of Schoharie. 
Cayuga County. In the slate near the village of Auburn, there are 
often found rounded masses of a dark coloured limestone, called Septaria. 
These are crossed in various directions by veins of celestine, among 
which minute crystals of calcareous spar are also observed. They 
usually have the form of the scalene dodecahedron, metastatique of 
Haiiy. Fig. 60. r on r 144° 20' 26"; r on r' 104° 28' 40"; r on r" 
133° 26' 0". These crystals deserve to be particularly noticed, in con¬ 
sequence of their association with celestine. 
Clinton County. According to Dr. Emmons, crystallized carbonate 
of lime occurs at the Finch ore bed. 
Dutchess County. Dark colored calcareous spar is found in the town 
of Rhinebeck, in this county. 
Essex County. In the town of Moriah, on 
Mill brook, near Port Henry, crystals of calca¬ 
reous spar are found in veins in white lime¬ 
stone. The forms which I have observed at this 
locality are similar to Fig. 58, and to those here 
introduced. Fig. 61 is the equiaxe, with the 
lateral angles replaced by planes. In Fig. 62, 
the replacing planes are still further extended, 
forming the doclecaedre of Haiiy. c on c 120° 0k 
In the town of Schroon there are translucent 
masses having a fine green tinge, from which 
cleavages of great beauty may be obtained. 
When held between the eye and the light, they bear a great resemblance to pearl, especially 
if of considerable size. They sometimes contain small scales of graphite. 
In Ticonderoga, at Rogers’ rock, there are often found masses made up of minute crystals 
of calcareous spar of the primary form, with grains of yellow garnet, and small but highly 
finished crystals of feldspar or albite. The whole are very feebly aggregated, and may be 
easily crumbled by the fingers. According to Cleaveland, hemitrope or grouped crystals of 
calcareous spar occur at this locality, but I have not been so fortunate as to meet with any 
specimens.
