DISTRIBUTION OF INTERNAL HEAT OF THE EARTH 531 



the material of the earth's interior, the paper discussed the primitive distribution 

 of the earth's interior heat under both the gaseous and the planetary modes of 

 aggregation, and drew certain tentative deductions relative to the possible conse- 

 quences of the secular redistribution of this heat. 



HAS THE RATE OF ROTATION OF THE EARTH CHANGED APPRECIABLY DURING 



GEOLOGICAL HISTORY? 



BY T. C. CHAMBEULIN 



[Abstract] 



Since the classic computations of George Darwin relative to the tidal relations of 

 the earth and moon, the doctrine of a high rate of terrestrial rotation in early geo- 

 logic times has been widely accepted and has been made the basis of deductions 

 relative to other important questions. The paper attempted to test the validity 

 and quantitative applicability of this tenet by means of geologic phenomena, es- 

 pecially those of crustal deformation and the relations of sea to land. 



The Society adjourned. No evening session was held, but the Fellows, 

 with invited guests, had the annual dinner at the Whitcomb house. 



Session of Thursday, January 2 



The Society convened at 10 o'clock, Vice-President Winchell in the 

 chair. No business was offered and the reading of papers was resumed. 

 The first two papers were read and discussed as one. 



USE OF THE TERMS LINDEN AND CLIFTON LIMESTONES IN TENNESSEE GEOLOGY 



BY AUGUST F. FOERSTE 



[Abstract] 



The Lower Helderberg was named in Tennessee from its exposure at Linden, 

 where it is but 12 feet thick, while the maximum thickness is between 75 and 100 

 feet. The advisability of naming a formation from its place of minimum exposure 

 was questioned. The faunal and stratigraphic characters were given. 



BEARING OF CLINTON AND OSGOOD FORMATIONS ON AGE OF CINCINNATI 



ANTICLINE 



BY AUGUST F. FOERSTH 



[Abstract] 



In continuation of former studies the author developed his interpretation of the 

 Cincinnati anticline. The Devonian axis of the anticline is northeast and south- 

 west, while the topographic axis is north and south. The Clinton strata over the 

 central part of the anticline are coarse lime-sands with wave-marks and cross- 

 bedding, and beds of conglomerates. North and south of this area the material is
