secular summer. Particular description and geograph- 

 ical effects of the four seasons of one of the most glacial 

 of the great secular years. Evidences in the earth's 

 strata of previous glacial periods ; and the help which 

 they give towards estimating the age of geological epochs 

 and of the world. - 31 



UNIVERSITIES YS. SCIENCE. 



An attempt to represent the arguments and convictions of 

 the good Methodist curators of the Yanderbilt Univer- 

 sity, of Nashville, Tenn., when they removed Prof. 

 Alex. Winchell from his Lectureship in Geology on 

 account of scientific heterodox opinions. Showing 

 the unfavorable influence on religious tenets, and the 

 logical materialistic conclusions, that must follow from 

 modern scientific teachings, and particularly from the 

 Darwinian .theories. - - 43 



WHAT THE CHEMISTRY OF THE ROCKS TEACHES. 



The nebular theory of the origin of the earth proved from 

 the chemical condition and composition of the rocks. 

 The order of position of the gases and vapors of minerals 

 in the atmosphere, according to their specific gravities. 

 The oxidation of silicon arid formation of the granites 

 would be the first result of consolidation. Then fol- 

 lowed the great storms and down-pourings of the metals 

 in their order, the most infusible first. Then the for- 

 mation of water, bringing down sulphuric and carbonic 

 acid in solution. The succession of the strata in the 

 earth corresponds to what would be the order of com- 

 bination and condensation in the atmospheric strata. 

 The constitution of the other planets as judged of by 

 chemical laws. - 53 



THE GENESIS OF WORLDS. 



Outlines of the " Nebular hypothesis." Action and trans- 

 mutation of the forces engaged in the consolidation of 

 worlds from the gaseous state. First effect of the 

 condensation of gases is heat. To a certain extent 

 this heat is transformed into the motion of the masses, 

 that is planetary revolutions ; the remainder is radiated
