Mr. Boyles 60 Foot Teleseope, therc was perccived a little os the Limb osthc Moon without the Disk of the Sun : which seemed to tome os the Ob*servers' to come srom tome shining Atmolphere about the Body either os theSun or Moon. They affirm to have obferved the Figure os this Eclipse, and >measured the Digits, by casting the Figure through a 5- Foot Teleseope, onan extended Paper, fixt at a ccrtain Distance from the Eye-Glaß, and ha-ving a round Figure j all whosc Diameters were divided, by 6 ConcentrickCircles, into 12. Digits. ;

z. The Eclipfc Bcgan at 5* 1 . 44s yiC mane. It Ended at 7^. 43s 6".

So that its whole Duration was. i h . 58h 14". The greatest Oblcuration was uh ,* y * n ’7 Dig. yc/. but it seemed to have been greater by 3'. which M. Paycn imputesto a particular Motion of Libration of the Sun’s Globe, which entertained,that Luminary in the tarne Phasis for the space of 8 ; . and somc Seconds,as is it had been stoppcd in the midst of its Course; rather than to a Tre-mulous Motion of the Atmofphere, as Schciner would have it. The Appa*rent Diameters were »lmost Equal : for in the Phasis of 6 Digits , the Cir*cumference of the Moon’sDisk pafled through the Center of that of the Sun,so as that two Lines drawn through the two Horns of the Sun, made witb"the common Semidiameter two Equilateral Triangles.

The Beginning and Middle of the Eclipse happened to be in the NorthEastern Hemilphere, and the End In thc South Eastem. The first Contadts as ’twere ) of the two Disks, was observed in the Superior Limb of thc.

Sun’s Disk in relpect to the Vertical Line, and in the Inferior in refpect tothe Ecliptick. But the Middle and the End were seen in the Superior Limb,in relpect both to the Vertical and the Ecliptick.: And what to M. Payeuseems extraordinary, both the Beginning and the End of this Eclipse hap-pen’d to be in the Oriental Part of the Sun’s Disk.

Thirtyseven Parts of the Sun’s Diameter remained Light, and 6 3 wereDarkned.

4. In this Eclipfc it is chiefly obscrvable, That thc Semidiameter of the ob Dantzick-v

Moon, from the very beginning to about 5 or 6 Digits of the Increasing b M.Havdiua.Phasis, was almost equal to the Semidiameter of the Sun : but, aster the "* l9 ’ * 47 ’

greatest Obseuration, when I again contemplated the Moon’s Semidiameter, I

found it 8 y/ . or f f . bigger than that of the Sun ; so that thg Semidiame-ter of the Moon was not always, during this Eclipfc, constant to it seif. I

Of this Variation, the Excellent Ifnacl ButlialJus hath also observ’d some- 1

thing at Paris. For he has written to me, that in the tarne Edipfc, theSemidiameter of the. Sun to the Semidiameter of the Moon was, as i6'. f. • j

to l 6 '. rz". but that in another Phasis of 6 Digits, the Semidiameters ap- I

peared equal.
