The position here given compared with that of 1822.16 



(Philosophical Transactions 1824, III.) indicates a change of 



only — 0° 17', being smaller, it is true, in quantity than the 



change ( — i<* 35') which ought to have taken place on the 



supposition of the angular velocity of — o°-5 14 there assigned, 



but in the right direction. If we recollect that the angle of 



1822 is deduced from a mean of only 8 individual measures, 



it will not appear surprising that an error of a degree or 



somewhat more should have been committed in it. In such 



a case the coincidence of directions is in itself a confirmation 



as good as we have a right to look for. (H.) ^
