.Hence it appears, That the Solsticial Heights were very nearly the farrte attisumiburg ioo Years ago as now they are, that ,of the Stirnfner Solstice be-ing but one Minute diftering, the other only io", both which may poifiblyarile from the Desects of the Instruments of diese Observers, being made with„Plain Sights ; but vvhat I shall neceflarily conclude from hence is, That is-there be soch a Motion of the Poles, it is cither very flow, or else nearly atRight Angles to the Meridian of Nurenburg ; in which latter cale, the Lati-• rudes of Places about Tunkiv?-, Siam, Mal aeca, and Java, on the one side •and in our American Plantations of Nerv-England, Virginia, Jan: alea, &c. onthe other, ought to change fältelt but I ha ve never yet heard of any such(hing oWerved by any of our Navigators ; whencc if there be such a Changeof the Eartlis Poles, it mult neceflarily require a long time to becomc sen-sible.

Besides, from the (e Observationi, it appears, That the Obliquity of rheEeliptick has continued unalterated for these ioo Ycars last past ; that is to,lay, that the Angle which the Earth’s Axis makes with the Plain of the Ec-Jiptick or Orb wherein stie moves Annually round the Sun, has been with-put lei)sible Change in all that time ; which will be very lvavd to conceive,.if we allow a Translation of the Earth’s Poles ; for the direction of the Axisbeing jierfectiy ak libertv, it must be purely casoal, if it lö hit, that asicr suchChange, it make the lame Angle with tbeEeliptick Ls before.

A hirther Argument of this Slownels of the Change of the Poles, is tlieJLutitude ot Alexaniria, the Habitation ot those famous Astronomers of An-riquity, Eratostbenes, Timccharis, Hipparchus , and Ptolomy, and for that rea Ionit may be condudcd, that this, of ali the Latitudes the Ancients have lest us,ought to be one of the moli Correct. This by Ptolomy is faid to be zcA y8'-North, (which he ules in all his Computations in his Alsncgist, and seems de-rived from the proportion of the Gnomon to its Equinoctial Shadow, as y to 3.)but in his Geograph y, 31 0 . just. In the Year 1638. the Curious and Inge-niolis Mf. Greavcs, when he went to visit the Egrptian Pyramids, of which sichas given so good art account, did with a sofhcient Instnament observe rheLatitude of Alexandri a, and found it 31°. 4k or 6 Minutcs more chan it isreputed by Ptolomy , and before him by Eratostbenes ; lb that in about io00Years the Latitude of Alexandria lias altered only a few Minutes, and so few,that the Accuracy of the Obscrvations of the Ancients may well be questioned:but both being granted, this Motion will amount to no more than a Degreein ioooo Years.

This is siiid not with intent to Invalidate whatMr.Hae^ hath from so goodGrounds advanced, vi\. That the Ball of the Earth, at least the Fluids there-'of, being neceflarily of the Figure of a Sph.croidcs Prolatus, or flat Oval,vhoie fhortest Diameter is the.Axis, and greatest Circle the Equinoctial; ifthe Poles be liippofcd esianged, the Equinoctial will 1 be so too; and conle-quently the. \ Vater must rise and covcr those Parts from which xhe- Poles re-cede, and fall oft, and leave bare thole Places towards which the Poles ap-proadi. By this nieans it may be accountcd for, how such stränge Marinethings are found on the Tops of Hills, and 16 decp under Ground ; and Icarcc
