'U. S. Naval Observatory, Washington. D. C. 

 'Dear Sir, — Your Painting of the Moon arrived safely, and was inspected by all the gentlemen con- 

 nected with the Observatory. They at once agreed that, so far as colouring is concerned, it is a remarkably 

 artistic representation of our satellite ; but the equally important question of accuracy of outline was not so 

 easily settled. To test it, Admiral Rodgers directed Assistant Astronomer Paul to compare the picture with 

 some of the best lunar maps, and, I am happy to say, the result was all that could be desired. The details 

 are perfectly correct, not only in the illuminated portions, but even in the dark parts, which shine only by 

 earth-light. I therefore congratulate you on having produced a most faithful portrait of the moon as seen 

 through a good telescope. I also enclose a letter from Admiral Rodgers to myself, which you will find of 

 interest, and remain, ' Yours very truly, 



' Wm. Harkness.' 



'TL S. Naval Observatory, Washington, D. C. 

 ' Dear Professor, — The picture which you showed me of the new moon, in oil, by Mr. Henry Harrison, 

 is excellent. It is more like the moon itself, as seen through a telescope, than anything I have seen. It has 

 been compared with Schmidt's and with Neison's maps of the moon, and it is found to agree exceedingly 

 well with those very accurate representations in the configuration of the lunar surface. 



'Very truly yours, 



'John Rodgers, 



'Rear Admiral and Supt. 

 'Professor Wm. Harkness, R. S. Navy, IT. S. Naval Observatoiy, Washington.' 



'U. S. Naval Observatory, Washington, D. C. 

 ' We have examined Mr. Harrison's picture of the Moon and think it one of the best that we have ever seen.

'Edward S. Holden. Edgar Frisby.'

'Henry Harrison, Esq., 



' Dear Sir, — Your Painting of the Moon appears to me to possess great artistic and scientific interest. It 

 certainly presents the telescopic aspect of the Moon more truthfully than any drawing I have yet seen. I think 

 chromo-type copies of your series of paintings would be of great use in science teaching. 



'Yours truly, 



'R. A. Proctor.'
