The same mineral, in large but imperfect crystals, occurs near Kirby’s graphite mine, four 
miles northwest from Ticonderoga, where it is associated with pyroxene and scapolite. 
Lewis County. Near Natural bridge in the town of Diana, sphene 
occurs in crystals of a dark chocolate-brown colour, with pyroxene, 
scapolite and feldspar. The crystals are usually small, but often very 
perfect, and have the form of the primary (Fig. 519); also that repre¬ 
sented in Fig. 525, and several other modifications, which are sup¬ 
posed to belong to a distinct species (see Appendix to Sphene.) 
New-York County. Small brilliant crystals, in form similar to 
Fig. 521, of a light dove colour, have been found imbedded in the 
primitive limestone at Kingsbridge.* 
Orange County. There are several localities of sphene in this county. One of the most 
interesting is near Duck-cedar pond in the town of Monroe, where it occurs in great abun¬ 
dance, and in crystals of large size, in primitive limestone. 
This mineral also occurs near the outlet of the Two ponds in the town 
of Monroe, where it is associated with pyroxene, scapolite and zircon in 
white limestone. The crystals have a dark chocolate-brown colour, and 
are often of considerable size. 
The forms observed in this town are the primary (Fig. 519); Figs. 
521, 522, 523, 524, 525 ; and Fig. 526, spinthere of Haiiy. P on a 159°

In the town of Warwick, sphene occurs in rounded grains and imper¬ 
fect crystals, disseminated through limestone, with hornblende, etc., in
