Providence, Mv. ISth, 1823. 

 "In the course of last summer I visited the followiiig lo- 

 calities of minerals. Some of them have been known a long 

 time to individuals ; but none of them have been noticed in 

 the Journal of Science. 



1. Feldspar, in regular crystals of an inch and a half in 

 diameter, at Barkhampstead. 



2. Actynolite in potstone, at do. 



3. Graphic granite, at do. 



4. Ferruginous Quartz, at do. 



5. Black mica, at A ew Hartford. 



6. Prismatic do. at do. 



7. Radiated quartz, at Canton. 



8. Kyanite, from a new locality in Chatham. 



The specimens which I obtained, were taken from a ledge 

 in the turnpike road, leading from Middletown to Middle 

 Haddam, a few rods east of Mr. Asher Rowley's. The 

 crystals are imbedded in quartz, and cross each other in ev- 

 ery direction. Their colour is generally a pale blue, with 

 occasional spots of deep blue. 



9. Garnets, in mica slate, at Middle Haddam. 



They are found about eighty rods east of the Landing. 

 They occur in vast abundance, and are from one to two 

 inches diameter. Those which have been noticed, are 

 found at the Cobalt mine, and are small when compared 

 with these. 



10. Epidote at Plainfield. 



11. Gneiss curiously stratified at do. I have a speci- 

 men three fourths of an inch thick, wnich contains ten dis^ 

 ti net layers.
