Six lectures by Prof. Benjamin Pierce, of Cambridge, Mass., on

 gress of Architecture in relation to Ventilation, Warming, Lighting, 

 Fire-Proofing, Acoustics, and the general preservation of Health." 



The operations of the Institution have been continually expanding, 

 and it is with difficulty they can be kept within the limit required by 

 the Smithsonian fund. So far, therefore, from wanting general fields 

 of usefulness, the opportunity of doing good is only restricted by the 

 amount of means which can be employed. 



Respectfully submitted. 



JOSEPH HENRY. 



Washington, January, 1857.
