214 LUNAR PHOTOGRAPHY. [MEMOIR XIV. 



NOTE ON LUNAR PHOTOGRAPHY. To the foregoing 

 paragraph respecting photographs of the moon, I may 

 here add an extract from a publication by my son, 

 Dr. Henry Draper, in the Smithsonian Contributions to 

 Knowledge, No. 180, p. 33, entitled, " On the Construction 

 of a Silvered Glass Telescope, and its Use in Celestial 

 Photography :" 



"The first photographic representations of the moon 

 ever made were taken by my father, Professor John W. 

 Draper, and a notice of them published in his quarto 

 work 4 On the Forces that Organize Plants,' and also in 

 the September number (1840) of the London, Edin- 

 burgJi, and Dublin Philosophical Magazine. He pre- 

 sented the specimens to the New York Lyceum of Nat- 

 ural History. The Secretary of that association has 

 sent me the following extract from their minutes : 



"< March 23d, 1840. Dr. Draper announced that he 

 had succeeded in getting a representation of the moon's 

 surface by the daguerreotype. . . . The time occupied was 

 twenty minutes, and the size of the figure about one inch 

 in diameter. Daguerre had attempted the same thing, 

 but did not succeed. This is the first time that any- 

 thing like a distinct representation of the moon's surface 

 has been obtained. ROBERT H. BROWNNE, Secretary. 1 ' :
