In his third Demonstration; _page_ 71: _line_ 7. _Producta _Y P_ transibit per _M_;_ is said _gratis_; nor is any proof offered for it. And so this whole structure falls to the ground. And withall, the _Prop._ 47. _El._ 1 doth still stand fast (which he tells us, _page_ 59, 61, 78. must have Fallen, if his Demonstrations had stood:) And so, _Geometry_ and _Arithmetick_ do still agree, which (he tells us, _page_ 78: _line_ 10.) had otherwise been at odds. And this (though much more might have been said,) is as much as need to be said against that Piece. * * * * * Printed with Licence for _John Martyn_, and _James Allestry_, Printers to the Royal Society. {295} * * * * * _Num._ 17.

Its _greatest Obscurity_ somewhat more than 7. digits. About the middle, between the Perpendicular and Westward Horizontal _Radius_ the Sun, viewing it through Mr. _Boyle_'s 60. foot-_Telescope_, there was perceived a little of the Limb of the Moon without the Diske of the Sun: which seemed to some of the Observers to come from some shining _Atmosphere_ about the Body either of the Sun or Moon.
