Hand-book of electro-therapeutics
A 1910 medical handbook on electro-therapeutics by William James Dugan, published in Philadelphia by F.A. Davis for physicians treating patients with electrical apparatus. Engraved equipment plates show Victor-brand induction coils in pebbled carrying cases, electrodes, cords and glass applicators, drawn with stippled shading and dotted cutaway lines useful as period instrument silhouettes, trade-name lettering, and technical diagram texture.
