with AlJanite, the above angles, as they were taken with the reflective 

 goniometer, should be substituted for those usually given, which were 

 obtained with the common goniometer. 



I have not observed any terminal planes, but infer the probable obli- 

 quity of the primary, from the direction of a seam of carbonate of lime, 

 w'hich intersected the crystal. If we can place any dependence on this 

 kind of evidence, the crystal is oblique from an obtuse edge. 



The scapolite in which the mineral is found, contains, also, exceeding- 

 ly minute zircons, scarcely ^V inch long, and also very small prisms of 

 rutile. The zircons are square prisms, having the lateral edges trunca- 

 ted, and pyramidally terminated at each extremity ; a narrow intermedi- 

 ary plane replaces the edge between a pyramidal plane, and one trunca- 

 ting a lateral edge. They are described in Naumann's System of Crys- 

 tallographic Notation, as follows : oo P oo . oc P.P.3P2. J. D. Dana.

4. New locality of Cncldonite. — This mineral is found in the north 

 part of Litchfield, Ct. about two miles from the village. The locality is 

 upon the east side of the road, leading from the Wolcottville turnpike to 

 Torrington, on the land of Mr. John A. Woodruff. It occurs crystalli- 

 zed in short hexagonal prisms, with the alternate angles replaced by 

 single planes, inclining upon the base, at an angle of 121°, and upon the 

 lateral planes, at an angle of 134". The largest of the crystals are 

 about three quarters of an inch in length, and two and one quarter inches 

 in dianieter. It is found imbedded in fragments of rock composed of 

 quartz and mica slate. The prevailing rock is mica slate, from which 

 these probably have been detached. 



The mica slate also contains an abundance of staurotide. A common 

 form of the crystals is that of the primary form, with the obtuse angles 

 replaced. Some of them are four inches in length.

5. Stilbiie, Chahasie, and other minerals, at Stonington, Ct. — Stilbite 

 has been found within cavities in gneiss on the Stonington rail road, two 

 miles and a quarter from that village. It is imperfectly crystallized, being 

 composed chiefly of implanted globules, with occasional botryoidal mass- 

 es, which, when broken, present the stellated structure common in this 

 species. It is of a wax-yellow color, and subresinous lustre. Some speci- 

 mens are of a light yellow color. 



Chahasie. — In connection with the above, were found very minute 

 crystals of Chahasie, of a light red color. But in a ledge on the rail 

 road, a quarter of a mile further from its termination at Stonington, were 

 found in rather more abundance, aggregated crystals of a deep carnation 

 red color. The crystals are very obtuse rhorabohedra, from one fifth to
