 nificance of the work in which it was engaged, and its rela- 

 tions to the scientific questions of the day. During the first 

 ten years his papers were but few. At the meeting of the 

 American Association in 1850, he remarked, at the conclusion 

 of a brief conversation, that for the last three and a half 

 years all his time and all his thought had been given to the 

 details of the business of the Smithsonian Institution; he had

 sistants, that he would be enabled, in part at least, to return 

 to his first love the investigation of the phenomena of 

 nature. * 



His anticipations were not, however, to be realized in the 

 manner hoped for. His subsequent work in science was for 

 the most part that which grew out of his official connections, 

 and his published papers such as embodied trains of thought 

 suggested by the administrative work which he was directing. 

 His studies upon direct and reflected sound grew out of 

 his experiments to remedy the defects of a Smithsonian hall
