The geological papers were: (1) The Relation of tlie Cretaceous 
Deposits of loira to the Suhdivlsioits of the Cretaceous projiosed 
■hy Meek and Ilayden, and (2) Note on the Structure and probable 
Ajfinities of Cerionitrs dacti/loidrs Owen, by 8. Calvin. (8) Nat- 
ural Gas and Oil in loud, :ind (4) Some Mineralogical Notes, by 
C. R. Keyes, (5) From Ford to Winterset, by J. L. Tilton. The 
"Other papers were chietly biological. The Academy is fortunate 
in that the legislature, at its last meeting, provided for the publi-

A New Meteorite. A meteoric body of an estimated weight 
of twenty tons fell in the vicinity of Jiminez, Chihuahua, Mex-

The Kansas Board of AciRrcrr/ruRE has ai)pointed Prof. C. 
S. Prosser of Washburn (!olleg(!, one of the geologists of the 
Board. Notwithstanding there is no authorized geological sur- 
vey of that state in progress, there is prospect that the explora- 
tions of Prof. Prosser will result in considerable additions to our 
knowledge of its geology, for he intends to enter upon a season's 
work in the regions of the Carboniferous and Permo-Carbonif- 
K-^rous. 
The State Com.kije ok Kentuckv, Lexington, has just estab- 
lished for the first time the department of Geology, and A. M.
