Experiments on magnetic vibration at the Singapore Observatory, by Charles Morgan Elliot Tables and calculation from experiments on vibration for moment of rotation, conducted on the verandah of the Observatory, using magnets D5 and D6: columns for times of observations, means of observed times, differences, number of vibrations, time of one vibration, temperature of vibrating magnet, bifilar readings and temperature, readings at extremes of vibration and semi-differences. With determinations of the coefficient of torsion. Headed [p.1]: 'May 1845 No.1 Experiments of vibration for moment of Rotation'. Not signed. 1-2 May 1845
