 plates). (Smithsonian serial No. 1738.) 



The preface of the volume states : 



" The Astrophysical Observatory of the Smithsonian Institution was founded 

 through the efforts of the late Secretary Langley, who was its director until 

 his death. The research described in the present volume is a continuation 

 of the work on the relations of the sun to climate and life upon the earth, of 

 which he was a brilliant pioneer investigator.' 



" Mr. Langley expressed the hope that careful study of the radiation of the 

 sun might eventually lead to the discovery of means of forecasting climatic 

 conditions for some time in advance. It is believed that the present volume 

 will aid maferially to show how far that hope may be justified, for it contains 

 careful and comparable measui'ements of the solar radiation, extending over 

 several years. These indicate that the sun's radiation alters in its intensity 

 from time to time, and that these alterations are sufficient to affect the tempera- 

 ture of the earth very appreciably." 



A short note on the " Reflecting power of clouds " to accompany Volume II of 

 the annals was in press at the close of the year.
