46, line 5, for "13th," read "30th."

56, line 6 from bottom, for "discrepancies," read "discrepances."

57, for lines 3d and 4th, read "gives ${\frac {1}{298\cdot 33}}$ for the compression deduced from arcs of the meridian."

59, Note.—The effect of local attraction on the pendulum is so great, that it has rendered the experiments made with that instrument for the purpose of ascertaining the compression of the earth very uncertain. Mr. Baily, President of the Astronomical Society, has devoted much attention to the investigation of this subject. He finds that the experiments of Captain Foster, whose early loss is so justly lamented, give a compression of ${\frac {1}{289{\dot {4}}8}}$; those of Captain Sabine give ${\frac {1}{288{\dot {4}}0}}$; the mean of the French and Russian experiments give ${\frac {1}{267\cdot 23}}$; from the mean of the whole Mr. Baily deduces the compression to be ${\frac {1}{285\cdot 26}}$; but even this is not conclusive.

64, line 7, for "92246700," read "95296400."—Line 8, for "ninety-two," read "ninety-five."

Note.—If the computation be made with the more accurate parallax 8′′⋅5776, the sun's distance is 95070500 miles.

67, line 8, the quantity ${\frac {1}{1053\cdot 924}}$ representing the compression of Jupiter, was not deduced from Encke’s comet, but from the perturbations of Juno.

Note.—Professor Airy has recently determined the most accurate estimation of the value of the mass of Jupiter to be ${\frac {1}{1048\cdot 69}}$ deduced from the elongation of the fourth satellite: he has also found that the mass of the whole Jovial system is ${\frac {1}{1048\cdot 70}}$, showing how small a proportion the mass of the satellites bears to that of the planet.

68, line 8, for "886860," read "886952."

88, lines 7 and 8 from bottom, for "radius," read "diameter."

99, line 7, for "poles," read "pole."

128, lines 1 and 2 from bottom, for "volume," and "volumes," read "atom" and "atoms."

129, lines 1 and 3, for "volumes" and "volume," read "atoms" and "atom."

132, line 9, for "freezing," read "zero."

144, line 11, for "1090," read "1123."

220, line 3 from bottom, for "rays," read "images."
