Glauber, J.R. Libellus dialogorum, sive colloquia nonnullorum Hermeticae medicinae,

ac tincturae universalis studiosorum (...). Amst., J. Janssonius, 1663. 48 (of 92) p. 1 fold. plate (lacking sm. piece, not affecting image) w. 5 concentric circles showing the relationship among the sun, moon and salt. Later decorative paper boards. Sm. 8vo. Bound with: Idem. Tractus de medicina univeralis, sive auro potabili vero. (Ibid., idem, 1658). 49-92 p.

2 ex libris verso title-p., a few library stamps. The first work is lacking p. 49-92; the second is lacking p. 1-48; the two works were (interestingly) erroneously bound together. Glauber (1604-1670) was a German-Dutch alchemist and chemist.
