| Title | Paper, description of a hygroscope by Robert Hooke |
| Date | [1660-1679] |
| Description | A paper on weather by Robert Hooke. The illustrated instrument relies on a ripe wild-oat beard attached to a dial, which curls and straightens depending on the moisture in the air. Hooke indicates the dial should be created in the manner described by Emmanuel Maignan (Perspectiva Horaria (Rome, 1648), p. 89 and illustration).
