and in y [[superscript]] e [[/superscript]] Latitude. For it is evident that the Observations made at Sea may be more, but not less uncertain than those made at Land.
 7. Of these [[underlined]] Data [[/underlined]], being in Number about twelve, some depend upon one another. But by my Theory, and by the Tables or Observations of fixed Stars, they may be all sufficiently known, in order to establish this my Calculation; which may also serve for an instructive Example of the Calculations that may be made, in any other the like particular Case.
8. It is evident that if the Star, that is known to describe the Parallel DO, does either not ^ [[insertion]] at [[/insertion]] all disappear in M, or does only disappear near M for a very small or insensible Time; the Observator will be induced to conclude, That the Center of the Moon was at least 4'24'' more South than it really was; since the Star, as far as he knows, was not eclipsed at all.
9. And another known Star, passing about the same Time on the other Side of the Center C, at a Distance from it equal to CD, would induce another, or the same Observator to conclude, That the Center of the Moon was at least 4'24" more North than it really was; since the Star did also seem not to be eclipsed at all, when in or near the opposite Point N.
10. So we must leave those two Observators disputing, if you will, in Presence of a Flag-Officer, or else in a Royal Observatory; and differing from one another upon the best Astronomical Grounds, in the observed Declination of the Moon, by even more than 8'24"; till they reconcile themselves by other Observations, or by having recourse to the Refraction made in the Atmosphere of the Moon.
