ADVANCEMENT OF SCIENCE 

 FACT AND TBEORY IN SPECTROSCOPY'^ 



Before passing to some present problems 

 in physics, let us pause a moment to con- 

 sider the losses which our science has sus- 

 tained since the last annual meeting. 



The life and work of Professor Langley, 

 who died on the twenty-seventh of Feb- 

 ruary last, will long continue to form an 

 important chapter in the history of astro- 

 physics. To the study of this science he 

 brought rare skill, perseverance and clear- 

 ness of purpose. Among his most impor- 

 tant contributions is to be mentioned his 

 epoch-making determination of the distribu- 

 tion of energy through the spectra of vari- 

 ous sources, including especially the sun, 

 moon and firefly. His measurement of the 

 lifting power of an aeroplane driven at a 

 definite angle with a definite speed, his ex- 

 quisite discussion of the 'Internal Work of 

 the Wind' with its accompanying explana- 

 tion of soaring and his still later achieve- 

 ment of actual flight are matters which 

 have perhaps only recently received fair ap- 

 preciation. The recent performance of the 

 Wright brothers in Ohio and the flight of 

 Santos Dumont in a 'manned' machine are 

 but two events in the logical series which 

 Professor Langley did much to initiate. 



On the nineteenth of April, 1906, oc- 

 curred a great tragedy. Nothing in the 

 behavior of that remarkable element which
