282 CARNEGIE INSTITUTION OF WASHINGTON. 



special magnetic and electric observations at various stations in Australia 

 during the solar eclipse of September 21, 1922, by members of the Department 

 and other expeditions. At Perth and Wellington lectures were given on the 

 Earth's magnetism and electricity before representative scientific societies, 

 as well as talks before students of physics on problems of research in these 

 subjects. While homeward bound from New Zealand, the Director met 

 Observer D. G. Coleman at Rarotonga, and conferred with him with regard 

 to the continuation of the field work which he is successfully carrying out on 

 islands of the Pacific Ocean and in New Zealand and Australia. 



Library Work. — The number of books and pamphlets received during the 

 year from all sources was over 800, making now the total number of acces- 

 sioned publications in the library of the Department nearly 12,000. Mr. 

 Harradon, as librarian-translator, has, furthermore, made a large number of 

 translations for various purposes, and, with the assistance of Miss Noll, has 

 done considerable bibliographical work.
