have been added, one a heating and lighting plant, the other an 

 additional laboratory. An office and laboratory building is also 

 nearing completion for the department of Terrestrial Magnetism ; 

 this is situated near Chevy Chase, and in addition to other uses 

 will give opportunity for experimental researches in terrestrial 

 magnetism. The non-magnetic ship Carnegie has now nearly 

 completed a circumnavigation voyage of three and a half years 

 duration and aggregating about 92,000 miles. A fire-proof office 

 building has also been constructed at Pasadena for the staff of 

 the Solar Observatory. Dr. Woodward speaks feelingly and in 

 detail of the invaluable services rendered to the Institution by 

 the late Dr. John S. Billings. 



The President gives further a summary of the work accom- 

 plished by each of the separate departments. This is supple- 

 mented by detailed reports from the directors of the departments 

 and the recipients of grants for special investigations. These 

 reports fill the greatest part of the volume (pp. 55-322) and con- 

 tain much interesting information as to the work done, for 

 example, in botany at Tucson, Arizona; in experimental evolu- 

 tion at Cold Spring Harbor, L. I. ; in marine biology at Tortugas, 

 Florida ; in the Geophysical Laboratory at Washington ; the Mt. 

 Wilson Solar Observatory near Pasadena, etc. The publications 

 of the year include 29 volumes, with an aggregate of 6,600 

 octavo and 2,750 quarto pages, and 30 additional volumes are 

 now in the press.
