Registration of electric waves generated by a spark inductor, Groote Ruhmkorff, without capacitor, 4 cells by Grove. Opening discharges with spark micrometer. (Velin paper.), photograph, page, number: 'Pl. VII.', photographer: Willem Cornelis van Dijk, c. 1865 - in or before 1870, paper, albumen print, height 160 mm x width 129 mm, Photo on fifteenth unnumbered page after page 95., electrical phenomena, A large, pale rectangular sheet fills most of the image, bordered by a thin darker outline and mounted on a lighter background; the sheet shows faint, evenly spaced horizontal wavy pencil lines across its surface and a faint vertical fold line near the center, with occasional small smudges and pencil marks aligned along the left side of the central fold; the surrounding background is off-white with scattered brown age spots and subtle discoloration, and there is a narrow margin below the sheet with a line of darker printed text that is visible but not described.
