30. The mean of the above values of p and g were applied to the equations for 
August 12, November 14, and December 18 ;* on the first of these days deflections 
were made at three distances, and on the other two at four distances. The results of 
the equations are as follow :

* This method was recommended by Mr Airy (Proceedings of the Committee of Physics of the 
Royal Society, No. 1.) The results for Nov. 14 and Dec. 18, by the approximate formula (81.), shew to 
some extent how far it may be depended on. It should be remembered that the magnet was subjected 
to temperature experiments between Nov. 8th and 14th.
