It was found by the method described in Phil. Trans. vol. LXVI. p. 387, that the variation shewn by the instrument instrument is $9\frac{1}{4}$ too great, so that the mean variation is really only $22^\circ 11'$; and, therefore, as the variation at the Society's House seems to be $15\frac{1}{2}$ greater than it ought to be, by reason of the magnetism of the building (vide the same place) the true variation seems to be $21^\circ 55\frac{1}{2}'$. The reason why the instrument now shews the variation $9\frac{1}{4}$ too great, whereas before the errors was insensible is, that a small alteration has been made in the agate cap of the needle since the last year's observations, as it was thought not to have been fastened before in a sufficiently steady manner. ## DIPPING NEEDLE. | | 7 h.
