Abstract
A RECENT paper of mine, noticed in NATURE for February 27, p. 381, needs a correction, since the next issue of the Monthly Notices of the Royal Astronomical Society (p. 126) contains a correction by Prof. E. W. Brown to the calculated motions of the moon's perigee and node, which had stood for about twenty years. The change for the perigee is about three times what appeared to be the probable error of the previous value. Brown, in a letter to me, has queried the probable errors that I used ; but provisionally retaining them until better estimates are available, I have made a new solution, which is: J = 0.0016361 ± 0.0000059; l/e = 297.19 ± 0.52; Js = 0.000316 ± 0.000024; K's = 0.000115 ± 0.000048 ; f = 0.69 ± 0.06.
