Illustrations of a section through a part of Connecticut, 

 from Killingly to Haddam on the Connecticut river. 

 Am. Jour. Sci., (i) xxi, 94-97, 1832. 



Description and general relations of the following: granular feld- 

 spar rock and its passage into kaolin; granular quartz rock; gneiss in 

 thick strata; contorted gneiss; gneiss traversed with veins of granite; 

 mica slate; syenitic and hornblende rocks.

A geological map of New London and Windham coun- 

 ties. 



Am. Jour. Sci., (i) xxiii, 404, 1833. 



Notice of map based on geological data of Mather to be published by 

 William Lester, Jr. 



211. Mather, W. W. 



Sketch of the geology and mineralogy of New London 

 and Windham counties in Connecticut. 36 pp., map, Nor- 

 wich, 1834. 



A detailed study of the geology of New London and Windham 

 counties. The formations recognized are: i. Gneiss; 2. hornblende 

 slate; 3. mica slate; 4. granular feldspar; 5. granular quartz; 6. 

 sienite; 7. granite; 8. limestone; 9. tertiary; 10. diluvial; 11. alluvial. 

 Each of these groups is discussed under the following heads: (a) 

 Chemical and external character; (b) range and extent; (c) elevation 

 and general character of hills; (d) inclination and thickness of the 

 rocks and veins; (e) water and springs; (f) agricultural character; (g) 

 mineral contents; (h) application to useful purposes. Primitive and 

 Tertiary formations are present, but no Secondary.

Fossil fishes in Connecticut sandstone. 

 Neues Jahrb., 531-532, 1834. 



Specimens of fish turned to bituminous coal, but with scales per- 

 fectly preserved, are found twenty miles from New Haven; they oc- 

 cur in bituminous shale, " red marl," and sandstone. 



213. Mather, W. W. 



Geology of New York, Part I (first report on south- 

 eastern district), xxxvii + 671 pp., 46 pis., 4°, Albany, 1843. 



Glacial stri^e and till are noted as occurring in Connecticut, and the 

 origin of the drift deposits is discussed. The traps and sandstone of 

 Connecticut and New York are of the same age; the dip of the sand- 

 stone is due to the original deposition by equatorial and polar currents. 

 Identical Cambro-Silurian metamorphic rocks occur in western Con- 

 necticut and eastern New York.
