| Title | Letter from [Frederick Watson] Dyson, Astronomer Royal, Royal Observatory, Greenwich, to the [Royal Society] |
| Creator | Dyson; Sir; Frank Watson (1868 - 1939) |
| Date | March 1914 |
| Description | In relation to the Frere Altazimuth Sundial, designed to provide graphical solutions to problems related to the motions of the Sun. Highlights the complexity and high cost associated with its design, suggesting it may not be widely used due to its intricate nature. Questions the practicality of the instrument, suggesting that other methods, such as using a small sextant with Ball's Altitude Tables, would provide more precise results for time determination without the need for extensive adjustments. Ultimately, while the theory behind the instrument is deemed correct, its practical value is considered limited. |
