E. Jacobs, a celebrated Operator, New Orleans, says, "I have perused the work with much gratification as being much needed in the Art. I can sell a large number to pupils." From the _Ulster Telegraph_, Saugerties, N. Y.: "Those acquainted with the Christian character, and extraordinary skill of Mr. H. in Daguerreotyping, need no recommend from us. His pictures are perfectly exquisite, and his modes of operating of the most simple and scientific character. The Book will be a treasure to those engaged in the Art. It is one of those rare works which is as good as its title-page, and we heartily recommend it to the Daguerreian fraternity." Orders should be directed to S. D. Humphrey, Agent, New York.
