4. THE TERMS PLATTIN AND KIMMSWICK PROPOSED BY ULRICH 
The terms Plattin and Kimmswick were introduced by E. O. 
Ulrich, and made their first appearance on page 111 of the report 
of the Missouri Bureau of Mines, 2nd series, volume 2, published 
in 1904. Here it is stated that the term Kimmswick is proposed 
for the crystalline limestone exposed at Graysboro, Cape Gir- 
ardeau, Glen Park, and Kimmswick, and that the term Plattin 
was to be used for the starta between the Kimmswick and the 
so-called First Magnesian limestone farther down. Kimmswick is 
near the northeastern corner of Jefferson County, about twenty 
miles southwest of St. Louis; the type exposures extend from 
Kimmswick 8 or 9 miles southward to Riverside. Plattin Cre ek 
traverses the southeastern corner of the same county, and is 
about 18 miles from Kimmswick. 
5. THE AUBURN CHERT STUDIED BY BRANSON 
In 1909, Prof. E. B. Branson made a special study of the fauna 
of the chert occurring in the very fine-grained limestone in the 
vicinity of Auburn, a village in the north-central part of Lincoln 
County, about 6 miles south of its northern boundary, and prob- 
ably about the same distance from the type exposures of the 
Bryant limestone. Although apparently of about the same hor- 
izon as the Bryant limestone, the fauna studied by Branson has 
gone into literature as that of the Auburn chert. 
6. CORRELATION TABLES 
The terKLS McCune, Auburn, Bryant, and Folley were founded 
on exposures in the northeastern counties of Missouri, in Pike 
and Lincoln Counties. The terms Kimmswick and Plattin were 
drawn from localities in the southeastern counties of the same 
state, both in Jefferson County. In. Branson’s Geology of Mis- 
souri the terms Kimmswick and Plattin have been extended so 
as to cover also the exposures earlier defined as McCune, Bryant, 
and Folley, in the northeastern counties of the state. Judging 
from the Correlation Tables published in Bassler’s Index, Ulrich
