Scientific American, Vol. 81, No. 27 (December 1899)
A weekly issue of Scientific American from December 1899, published in New York for engineers, inventors, patent-seekers and technically curious general readers. Illustrations are dense black-line engravings and halftones of machines — dynamos, bench lathes on treadle frames, typewriters, ship and lift mechanisms — plus small advertising cuts with set type, useful as cutaway diagrams, machine silhouettes and period trade-catalogue filler.
