Scientific American, Vol. 2, No. 50 (September 1847)
A weekly issue of Scientific American from September 1847, published in New York for mechanics, inventors, and patent-seeking readers. Wood-engraved figures show bench-mounted machinery on plank tables, a square-cased dial with degree scale, loose hand tools and brushes in outline, and a crude fish-shaped banner reading VARIETY, giving letter-keyed diagrams and rough newspaper cuts for reuse.
