| Title | Letter from Humphrey Lloyd, Trinity College, Dublin to Edward Sabine |
| Date | 12 January 1848 |
| Description | Lloyd discusses solutions for the problem of the dip circle. Lloyd concludes that the angles of deflection were necessarily small, and such must be the case with every method in which two parts of the process are affected by the dip circle. Lloyd informs Sabine the adjustments to his own instrument made my [Henry] Barrow could be simplified. Lloyd agrees with Sabine to repeat the hygrometric tables. The same instrument and method may be used to determine the vertical component of the intensity, by simply turning the instrument into the plane perpendicular to the magnetic meridian and deflect as before. Discussion on obtaining the value of the dip. |
