Daguerreotype Rooms, Over D. Alden & Co’s Hat and Cap Store, Water Street, Augusta, Maine.  The subscribers would respectfully inform the people of Augusta and vicinity, that they have had long experience in their business, and have within the last six months made a simple discovery and decided improvements, which is highly pleasing to the operator and subject.  By this new beautifier and accelerating chemical agent, with our top-light and large apparatus, miniatures will be executed in the surprising short space of from 3 to 15 seconds, bearing any tone, from deep, rich shade, to the freshness of life.  Those having poor and spotted Daguerreotypes, taken by the old process, can exchange them for finished ones, (warranted not to change,) for the very low price of $1.  Ladies and Gentlemen are invited to call and judge for themselves.  Rooms open from 7 A. M. to 6 P. M.
