The thirty-second of fifty-one plates first published in Steven Blankaart's De nieuw hervormde anatomie ofte ontleding des menschen lichaams, Amsterdam 1686, with a Latin edition the following year. The plates are made up of uncredited reduced copies of previously published illustrations, several to a page. In the notes to this plate in James Drake's Anthropologia nova (London 1707, 2 vols), where the Blankaart plates were published in an appendix to the first volume, the figures are described as after Reinier de Graaf. They are from his book, De virorum organis generationi inservientibus, published in Leiden and Rotterdam in 1668. The following is a concordance of the illustrations, beginning with the Blankaart figures (which are usually the reverse of the De Graaaf originals): Fig. 1 = pl. I, fig. 1; fig. 2 = pl. I, fig. 3; fig. 4 = pl. III, fig. 2 (truncated) ; fig. 5 - pl. III, fig. 3; fig. 6 = pl. III, fig. 4; fig. 7 = pl. IV, fig. 4; fig. 8 = pl. IV, fig. 5; fig. 9 = pl. IV, fig. 6; fig. 10 = pl. V; fig. 11 = pl. I, fig. 2
