Referring to his former publications on the subject (Proceed. Roy. Soc. March 1842, Phil. Mag. 1842—51), the author empirically resolves the formulaht = H + ∑Ai sinit + ∑ai cosit = H + ∑Ri (it + Ѱi ),h being the effect observed at the hour-anglet , thus obtaining from the 24 hourly observations all values up toi =12. This method giving the values of Ai ,ai , R for the different months, he believes that by it the law of change connected with the sun’s motion in longitude and declination will be most readily deduced.
