 and section, 1888. Abstract: Nature, xxxvii, 500, 1888. 

 Review by J. Marcou: Am. Geol., ii, 10-23, 67-88, 1888. 



This exhaustive discussion of the Taconic question is subdivided as 

 follows: I. The Taconic area and geologic work within it; 2. Geology 

 of the Taconic area as known at the present time; 3. Geology of the 

 Taconic area as known to Dr. Emmons; 4. Comparison and discussion; 

 5. Nomenclature. (See Emmons, 115.) 



287. Walcott, CD.' 



Synopsis of conclusions on the " Taconic of Emmons." 

 Internat. Cong. Geol., Rept. Am. Comm., 25-29, 1888; 

 Am. Geol., ii, 215-219, 1888. 



Name Taconic " based on error and misconception originally, and 

 used in an erroneous manner since"; and should not be used as in- 

 dicating stratigraphic position.

Correlation papers, Cambrian. 



U. S. Geol. Surv., Bull. No. 81, 1-447, 3 pIs., 1891. 



Historical review of the geologic and paleontologic work, and sum- 

 mary of the present knowledge of the Cambrian areas of North America. 

 Mention of the quartzite of Canaan. 



289. Warren, J. C. 



Geological position of the Mastodon. 

 Boston Soc. Nat. Hist., Proc, iii, iii, 1849. 

 Brief mention of the remains of mastodons found in Connecticut, 

 " about midway between the Connecticut River and the Hudson." 



290. Webster, J. W. 



Localities of minerals, observed principally in Haddam 

 in Connecticut, in September, 1819. 



Am. Jour. Sci., (l) ii, 239, 240, 1820. 



Mention of tourmaline and epidote in mica slate and gneiss; chryso- 

 beryl in a granite vein traversing the gneiss, containing also garnet and 

 tourmaline; actinolite in mica slate; all of the above near Haddam. 

 Globular concretion of gneiss near Jewett City; tourmaline at Bozrah; 

 transparent garnets at Tolland, also graphite. 



291. Wells, D. A. 



On the Connecticut valley sandstone formations. 

 Boston Soc. Nat. Hist., Proc, iii, 339-340, 1850. 



The upper members of the Connecticut River sandstones are of an 

 entirely different age from the lower. This is evidenced by the limit- 

 ation of the fossils to the upper beds, and by the different lithological 

 characters. 



292. Wells, D. A. 



On the origin of stratification. 



Boston Soc. Nat. Hist., Proc, iv, 108-110, 1851; Am.
