| Title | Letter from Balfour Stewart, Kew Observatory to Edward Sabine |
| Date | 24 December 1859 |
| Description | Refers to Captain Blakiston’s unifilar apparatus giving ‘very good results’ and Stewart suggests the instrument should be suitable for [Colonel] Smythe. Stewart ‘will have the azimuth compass taken to Barrow’s’ for repairs. Stewart describes his method for obtaining the ‘bifilar coefficient’ and asks Sabine if he approves of it. Refers to trying Barrow’s nine-inch circle. |
