Scientific American, Vol. 59, No. 4 (July 1888)
A weekly issue of Scientific American, published by Munn & Co. in New York in July 1888 for inventors, engineers, and general readers following patents and new technology. The plates here are line engravings of a boy demonstrating Indian club exercises, each figure paired with dotted arcs and arrows tracing the path of the swing; useful for diagram-style motion notation, repeated-pose sequences, and period drill-costume figures.
