Spring lancet with case, 19th century. Lancet is brass and has a brass lever release. Engraved "Goulding/New York" (manufacturer). Case is made of wood, covered with black leather and lined with light brown plush. It has a tab closure. Lancet and case were not originally a set; the case was designed for a larger lancet. Donated by the American Pharmaceutical Association 1970. Lancet: L 40 mm, W 20 mm. Case: L 74 mm. W 38 mm. H 12 mm. NMHT 321641 (M-13060). Spring lancet with case, late 19th century. Silver lancet with a button release and a border decorating the top and edge. Button release lancets were sold in the late 19th century for slightly more than lever release lancets. Analysis by the Conservation Laboratory shows that the silver is not sterling but a silver-copper alloy containing twice as much copper as sterling silver. The button release is made of ferrous metal plated with silver. The blade and cocking lever are also of ferrous metal. The case is made of wood, covered with brown leather and trimmed with gold leaf. It is closed by an ornate clasp made of ferrous metal plated with brass. Donated by the American Pharmaceutical Association 1970. Lancet: L 42 mm, W 22 mm. Case: L 73 mm, W 40 mm, H 11 mm.
