D. February 16, 1846. — American Jovirnal of Science and Arts, 2d se- 
ries, vol. i, page 367. This was the MacropetaUchthyH raphe idohihis, 
and the description was the second notice of fish remains in the Cornif- 
erous. The genus was erected by Norwood and Owen.* 
1846. "Description of a Remarkable Fossil Echinoderm from the 
Limestone Formation of St. Louis, Mo., by J. G. Norwood, M. D., and 
D. D. Owen, M. D. June 23, 1846. — American Journal of Science and 
Arts, 2d series, vol. ii, p. 225. This was the Melonites multipora. 
The genus was erected by Norwood and Owen. 
1847. "Researches Among the Pi-otozoic and Carboniferous Rocks 
of Central Kentucky, made during the Summer of 1846," by D. D. 
Owen, M, D. and J. G. Norwood, M. D. St. Louis, 1847. This was an 
"excursion through part of Tennessee and Kentucky, by way of Nash- 
ville, Gallatin, Scottsville, Glasgow, New Haven and Bardstown," and 
was undertaken "with a view to clear up some doubtful points in west- 
ern geology." The authors say: "The points to which our attention 
was mainly directed were to determine whether the 'Cliff' formation 
of the west — the Upper Silurian and part of the Devonian rocks of 
Europe — existed in Tennessee and the southern part of Kentucky; to 
observe the succession, bearings and relative area occupied by the pro- 
tozoic and carboniferous or mountain limestone; and to collect, if pos- 
sible, a greater variety of fossils from the strata above the black slate, 
which occupy the knobby region of the Western States, in order to ob- 
tain additional evidence of the true age of these deposits, which have 
been usually regarded, on lithological grounds, as having been depos- 
ited contemporaneously with the Portage and Chemung groups of New 
York and the Devonian rocks of Europe." They identified the "Cliff" 
formation in various places and decided that the deposits in question 
above the black slate "belong to the Carboniferous [also referred to as 
'sub-carboniferous'] and not to the Devonian age." These "sub-carbon- 
iferous" Vjeds are now known in Kentucky as the Keokuk- Waverly se- 
ries, in part. The pamphlet is an interesting one on several accovmts. 
It contains one plate of fossils and a horizontal section of the beds along 
the line of observation. 
1848. First Report as Assistant U. S. Geologist in the Surve\- of the 
Northwest. 
1852. Second Report as Assistant U. S. Geologist in the Survey of 
the Northwest. 
Geological Report of a Survey of a portion of Wisconsin and Minne- 
sota made during 1847, 1848, 1849 and 1850. 260 i)ages, larg(> quarto, 
illustrated. Prof. N. H. Winchell, state geologist of Minnesota, has 
remarked upon the the thorough accuracy of this work of Dr. Nor- 
wood's.! 
*NoTE. — A portion of the specimen described and figvu-ed is now in the 
collection of Missouri University, Columbia. Coni])aring this with de- 
scription ot M. tiidlivantii, Ohio Rep., vol. i, Pal., 1 am covinced that it 
is the same species, and Norwood's specimen has jjriority. 
IDr. A. Litton, of St. Louis, I believe is the only person now remain 
ing who was engaged in that survey.
