1840 Hall of The Augusta House, Augusta, Maine.
Mr. Long was recorded in one announcement that appeared on June 13, 1840 in the Gospel Banner (Augusta, Maine). The Daguerreotype. Mr. Long, a competent lecturer, is in this place, and delivered a lecture and gave an exhibition on the Daguerreotype art at the Hall of the Augusta House on Monday last. In consequence of a misunderstanding amongst our citizens, the day not being supposed to be sufficiently pleasant for the exhibition, the attendance was small. He proposes to repeat the lecture and exhibition at the same place, this (Saturday) P. M. at 2 o’clock. Tickets 25 cents each. Those who were present on Monday are invited to be present again at that time gratuitously.
We have had some conversation with Mr. Long and are satisfied that his lecture must be highly interesting and valuable, as exhibiting many important facts in natural Philosophy. The pictures taken are to the very life. Nothing can be so perfect. Even images impressed upon the plate, which are, in the distance, to small to be minutely examined by the naked eye, will, by an application of the microscope, be enlarged and then every minute feature of the original will be distinctly seen . Nearer objects, of course, appear perfect. The exhibition is worthy of patronage.
Mr. Long (first name is unknown) is not recorded in other photographic directories as being active in Maine.
