187) call their [[underlined]] Præterition [[/underlined]], did fall into the same Mistake with myself. For, by what Mr [[underlined]] Cave [[/underlined]] has writ ^ [[insertion] t [[/insertion]] en to me, I conceive that the Distance of [[underlined]] Jupiter [[/underlined]] from the Moon, which was more than two Diameters of [[underlined]] his Body [[/underlined]] as observed with a Telescope at [[underlined]] London [/underlined]], was seen when [[underlined]] his Center [[/underlined]] was in the Line that terminated the inlightened Part of the Moon. And even this does yield a strong Suspicion that the total Eclipse of [[underlined]] Jupiter [[/underlined]] was visible at [[underlined]] London [[/underlined]]. 10. But as this Discourse is too long already, I intend to shew distinctly at another Time, How great are the Errors and Uncertainties to which we must be exposed in deriving the Place of an Observator at Land, or of a Ship, or of a Fleet at Sea, if we neglect that Refraction so often mentioned. For I reckon that the Errors and Uncertainties may amount to several Degrees in Longitude, and, in certain Cases, to 4 Minutes and 2/5 in Latitude. In short this Neglect has greatly perplexed and corrupted the Astronomy of the Moon. And upon that account I do not wonder that the Errors, in the Calculations of the Place of the Moon, do amount sometimes to four Minutes and a half, as Dr Hall ^ [[insertion]] e [[/insertion]] y told me in 17 [[strikethrough]] 8 [[/strikethrough]] [[insertion]] 2 [[/insertion]] 8. Of which Error I hope the greatest Part may now be avoided; but much more when I have publish'd what I have to say about what I call here enigmatically LVD, or 555. Gent. Mag. 1738 p. 130. Worcester.
