Theory, Description, and Directions for Setting Up Benjamin’s Improved Voss-Holtz Electrical Machine [wrapper title].

(New York: W. N. Oliver & Co., Printers, 12 Vesey St. 1885). First edition. 12mo, original light brown wrappers, 11, [1] pages. Illus. Two old light folds, some light wear and light soil; in very good condition. Item #18201

With an ad on the rear wrapper, “E. B. Benjamin, Importer and Manufacturer of Chemical and Physical Apparatus, Rare Chemicals and Laboratory Supplies of Every Description. 6 Barclay and 12 Vesey Streets, New York City.” Detailed explanation and promotional copy for this improved electric induction machine from a New York scientific instrument maker. The Vesey Street address of course is one to conjure by for students of medical electricity—12 Vesey Street later became the headquarters of the German Electric Agency, which made medicinal electrical belts and sold home batteries. (The relative proximity to the neighborhood that would become “Radio Row” seems also worth further investigation.) Not found on OCLC (which notes a single Benjamin trade catalog at Yale).
