Review: U. S. Geol. Surv., Min. Res. U. S. 841, 842, 1902. 



Deposit is in vein of very coarse granite. The tourmalines and 

 associated minerals occur in pockets lined with crystallized quartz and 

 feldspar, and sometimes beryl. The following minerals are described 

 mineralogically, chemically, crystallographically, also in regard to their 

 optical properties: — green and pink tourmaline, albite, microcline, 

 green and pink apatite, brown fluor, beryl, quartz, cookeite, lilac 

 lepidolite, greenish white muscovite, and a peculiar pink fibrous variety 

 of the same mineral. Other minerals: — green fluor, microlite, colum- 

 bite. 



9. Brace, J. P. 



Observations of the minerals connected with the gneiss 

 range of Litchfield county, Connecticut. 

 Am. Jour. Sci., (i) i, 351-355, i8i9- 



Location of the gneiss formation and its relation to the limestone, per- 

 phyritic granite or gneiss, and mica slate. Brief mention of minerals 

 found in the region; carbonate of lime over the whole region; cyanite or 

 sappar, especially at Harwinton and Litchfield; staurotide; quartz; 

 petrosilex, common in Litchfield and Goshen; common opal, in Litch- 

 field; rarely mica; schorl; feldspar; beryl; garnets; epidote, in Washing- 

 ton and Litchfield; tremolite, in Litchfield, Bethlehem, and Canaan ;^ 

 common asbestos in Washington and New Milford; augite, in Litch- 

 field; hornblende, actinolite, steatite, chlorite, and porcelain clay, in 

 Litchfield; graphite, in Cornwall; ores not common; red oxide of 

 titanium, sparingly in Litchfield.

Miscellaneous observations relating to geologj-, min- 

 eralogy, and some connected topics. 



Am. Jour. Sci., (i) iii, 216-221, 222-226, 1821. 



Mentions the serpentine of New Haven; notices the strong re- 

 semblance of the bituminous formation of Westfield, near Middletown,^ 

 to that of the bituminous marl slates of the copper mines in the coun- 

 ties of Mansfield and Hesse in Germany; fish impressions in each are 

 similar.

On a new and remarkable mineral locality at Branch- 

 ville in Fairfield county, Connecticut; with a description 

 of several new species occurring there.

 properties, chemical composition, and pyrognostics of various minerals.
