Fig. 42, triplante of Haiiy. Crystals similar to Fig. 43 have been found in 



Gouverneur. 



Wayne CorNTY. Rose-red and flesh-red crystals, highly modified, although seldom perfect, 

 occur in geodes in or near the stratum of lenticular iron ore at Wolcott. 



In addition to the above localities, I may state that heavy spar is almost always found in 

 laminae, in those rounded masses called Septaria. I have already noticed its occurrence in 

 this way in Schoharie county. It is also similarly met with near Auburn in Cayuga county, 

 Laona in Chautauque county, and Bufialo in Erie county. 



Heavy spar is of very frequent occurrence in the red sandstone near New-Brunswick and 

 elsewhere in New-Jersey ; and as it is by no means improbable that similar forms will be 

 found in the red sandstone on the Hudson, I here insert a few of the forms which I have 

 observed in addition to the primary (Fig. 29), which is quite common. These crystals are 

 usually small and tabular, and have almost always a white and opaque band around their 

 margins. They are associated with calcareous spar, and occur in veins and geodes.
