THE PHILOSOPHICAL SOCIETY OF WASHINGTON. 



The 590tli regular meeting was held No- 

 vember 12, President Marvin in tlie chair. 



Mr. Marsden Manson, of San Francisco, 

 presented by invitation a paper on ' The Evo- 

 lution of Climate.' In opposition to the mod- 

 ern views which attribute geological climate 

 to solar control and the glacial epoch to astro- 

 nomical causes, the author emphasizes the in- 

 fluence of the dense aqueous atmosphere 

 which must have surrounded the earth in 

 early times, and the change that occurred 

 when the sun's rays could reach the surface. 

 The ice-age was a transition period between 

 the long periods of earth-controlled and sun- 

 controlled surface temperature. His conclu- 

 sions were: 



1. At the dawn of geologic time two sources 

 of heat were active agents in the control and 

 conservation of temperatures, (a) earth heat.
