In the firft Sudlon S. Cafm fays, this Verification 
was the more confiderable, Fsrfi, becaufe it feil out to 
be made the Year before the laft Intercalation of the 
Gregorian Account (which u^as firft eftablillied in the 
Year 1582. Since which time" no Intercaiation has bten 
omitted, but the firft is to be omitted in the Year 1 700. 
to reduce the Anticipation of the Equinodials fince that 
time, and fo to make the Day of the Vernal Equinoj? to 
be the xith of March) By which opportune Occur- 
rence, this Line would afford a proper means to ot(erve 
exaftjy the time of the Sun's Ingrefs inro Aries, or of 
its paffing the Equinoftijl Circle. Secondly, Becaufe it 
would be a means for determining a Controverfy now 
much agitated among learned Men ; to wit, Whether

the Surface ol the Earth, do really alter or nor. Fcr that 
not only the prefent Poftures of them are found very dif- 
fering from thofe afljgned them by the ancient Geogra- 
phers : But confiderable Differences, a re alio found out 
amongft the more modern Obfervations, as in the pre- 
fent Meridian of Vraniharg, which has lately been foifnd 
by Monfieur Pkart, Erafmus Eartholinus^ and others, 
to vary 18 Mnutes towards the Eaft, from that fixed 
by the Noble Tycho Brc^he^ about 1 00 Years fince. And 
the great Pyramid of Egypt has been very lately found 
to ftand in a Pcfture that Two of its fides do rtfped: the 
South. Now Signior C^jJ?»/ having found by this !aft 
Reftification of his Meridian Line, that both the Mt^ri- 
dian and Parallel of Bononia^ have not been altered or 
changed now after 40 Years fpace;» conceives that there 
has not ever been any fuch Alteration as is (uppofed, 
but that thofe Differences that have been found at diftant 
times, have been occafioned by the Defeds or Miftakes 
of the Obfervations themftlves: Whence he conceives 
that the accurate Aftronomer, f^c^^?, was miftaken in the
