thereof. 
Firft therefore, after that M. Aun^outh^^d raifed fome fcruple 
againft the Contrivance of Signor Campani for making Gr^^/; 
Optuk^Gl(^jps without Moulds, hj the means of a Turn4ath , he 
examines the Ob/ervatmu^mzdQ with fuchG/^jj/'^/iWherCjhaving 
commended Campani s fincerity in relating what he thought to 
have feen in 6* ^i^/i^rfJ, without accomodating it to M,Hugens\ Hy^ 
pothefj^hc affirms, that fuppofing^ there be a T^ng about Saturn, 
Signor could not fee in all rhofe different timeSj that he 
obferved it, the fame J pp ear an ces, which he notes to have aHuaU 
/yfejen. For, having fcen it fomctimes in Tr^^^ JfpeH with the 
Sun,2in& Oriental j fometimes, in the fame JjpeB.hm Occidental i 
lometimes in Sextil Afpe^^^nd Oecident^^lt^ at another time^again 
in Tra^;and Oriental, this Author cannot conceive, how Saturn 
could in all thefe different times have no difference in its VhajiSy 
or keep always the fame Shadow i feeing that, according to the 
Hypothejij of the T^/z^jwhen it vj^^s Oriental^ it muft caft thtShad- 
is'ozp upon the /^/^ fide of the beneath , without cnfting any 
on the right fide : and when it was Occidental,\i could not but caft 
it on the right fide beneath, and nothing of it on the other. 
I Concerning the Shadorv ahwe , which affirms to be 
1 made by the King upon the Body of Saturn^ M. Au^tit judges ^ 
that there could be no (uchPhtenomefioTjjhy reafon of its Northern 
Latitude at the times, wherein iht obfervations were m^dQ^vid, iti

iiextfollowing5and in Jpril id<^4, except it were in (9So^^r,and 
ithe Shadorv ftrong enough to become vifible. 
But as to the Shadow belon>, he agrees with Campani,' that it 
does appear, yet not as he notes itjfeeing that it muft be fome- 
, times on the one fide,fometimes on the other; and towards the 
§^adrat with the Sun it muft appear biggeft,as indeed he affirms 
to have feen it himfelf this year, infomoch that fometimes it 
feemed to him,that it covered the whole 7^?>g,and that ih^Shad- 
joyning with the obfcure (pace between both, did interrupt 
the circumference of the fiing ; but beholding it at other times
