The History and Practice of the Art of Photography
New York, January 27, 1849. E. ANTHONY, ESQ.
Dear Sir,--In submitting the accompanying "History and Practice of Photography" to your perusal, and for your approbation, I do so with the utmost confidence in your ability as a practical man, long engaged in the science of which it treats, as well as your knowledge of the sciences generally; as well as your regard for candor. To you, therefore, I leave the decision whether or no I have accomplished my purpose, and produced a work which may not only be of practical benefit to the Daguerrean artist, but of general interest to the reading public, and your decision will influence me in offering it for, or withholding it from, publication.
If it meets your approbation, I would most respectfully ask permission to dedicate it to you, subscribing myself,
Ever truly yours,
HENRY H. SNELLING
