Surveying and drawing instruments
The Royal Astronomical Society seems to have accumulated small instruments that were not central to its primary purpose. On this shelf are small surveying instruments, such as box sextants [4, 5], prismatic compasses [3, 8] and an Abney level [6], and drawing instruments, such as protractors [9, 10] and pantographs [1, 11, which is an unusual form]. The protractors could have been used for plotting star charts; the artificial horizons [2, 7] could have been used with a sextant for some astronomical work.
