The Scientific American may be the oldest continuously published periodical in the United States, having launched its first publication in 1845. It has been a mainstay of popular science with in depth articles across a broad spectrum of scientific fields. In this supplement are short articles ranging through such topics as Camellias, Experiments in Memory, The Chemical Action of Light, and longer articles on the Gas Engine, and Optical Telegraphy. - Summary by Larry Wilson
