aperture Dr. Draper obtained pictures on silver plates, and 
presented them to the Lyceum of Natural History of New 
York. Daguerre is stated to have made an unsuccessful 
attempt to photograph the moon, but I have been unable to 
ascertain when this experiment was made. 
Mr. Bond’s photographs of the moon were made in 1850. 
The telescope used by him was the Cambridge (U.S.) refrac- 
tor of fifteen inches aperture, which gave an image of the 
moon at the focus of the object glass two inches in diameter. 
Daguerreotypes and pictures on glass mounted for the stereo- 
scope were thus obtained, and some of them were shown at 
the Great Exhibition of 1851, in London. Mr. Bond also 
proved the advantage to be derived from photographs of 
double stars, and found that their distances could be measured 
on the plate with results agreeing well with those obtained 
by direct measurement with the micrometer. 
Between the years 1850 and 1857 we find the names of 
Father Secchi in Rome, and MM. Berch and Arnauld in 
France ; and in England, Professor Phillips, Mr. Hartnup, 
Mr. Crookes, Mr. De la Rue, Mr. Fry, and Mr. Huggins. 
To these may be added the name of Mr. Dancer, of Man- 
chester, who, in February, 185£, made some negatives of the 
moon with a four and a-quarter inch object glass. They 
were small, but of such excellence that they would bear 
examination under the microscope with a three-inch objective, 
and they are believed to be the first ever taken in this country. 
Mr. Baxendell and Mr. Williamson, also of Manchester, were 
engaged about the same time in producing photographs of 
the moon. 
The first detailed account of experiments in celestial 
photography which I have met with is by Professor Phillips, 
who read a paper on the subject at the meeting of the British 
Association at Hull in 1853. Professor Phillips says : — “If 
photography can ever succeed in portraying as much of the 
moon as the eye can see and discriminate, we shall be able to
