An Account of fame Ohfervations lately made at Nu« 
rcnburg by Mr. P. ^Mmdh-mt^fhewing that the 
Latitude of that Place has continued without fenfbh 
alteration for qoo Tears laft paji^ as lih^wife tbe 
Obliquity of the E^liptickj^ by comparing them with 
what w^s obfer^ed by Bernard Walther in the 
Tear 14S7 being a Difcourfe read before the Royal 
5bciety inoneof late Meetings. 
WHether the Poles and Axis of the Earth be really 
fixt in the Globe, or fubjefit to be transferred from 
place CO place is an old Enquiry, though now lately re- 
vived by Mr. Hook in his ingenious effays upon the great 
mutations and Catajlrophies which in all appearence 
have hapned to the Earths Surface. A neceifary conle- 
qvence of fuch a tranflation of the Poles would be the 
change of the Latitudes of places, which would encreafe 
in thole Regions towards which the Poles approach, and 
decreafe in thofe from which they recede: and under the 
Meridian 90 degrees removed from that in which the 
Poles ihift, the Latitudes continuing the fame, the Me- 
ridian line woujd only Alter; but no two places confi- 
derably differing in Latitude can be fuppofed, wherein if 
there be any ienfible motion of the Poles, it fliall not be 
perceived by the alteration of the Latitude of one or both 
of them. 
The accurate Mr. Wurtzelhaur^ has lately furniihed us 
with the means of examining this Hypothefis by oblerva- 
j tion, having lent us the Meridian Altitudes of the Sun ta- 
ken at Nurenhurg about the twoSolftices in the Year 1686. 
jf^;?^ the lo^^.he found the Meridian altitude of 0 64^^. 
2m:ios, and the next Day G^^gr.xm. 25s. and on December 
1 4°. 3 days after the Solftice, wherein the Sun was got two 
minutes higher, he found the Meridian Altitude I'jgr.
