lilhed, that on the^o.day ot July, iffy, at iL of the dock in 
the morning, he had obferv’d , with Campani s Glaffes, that 
there paffed through the broad obfcure of Jupiter twdob- 
fcurer-/j&Wj>by him efteemed to be the Jljadorvs of the Satellites, 
moving botw eenjupiter& the£a??,and ech'pfing him, and emerg- 
ing from the Occidental Brim thereof: This A nth our did fir ft 
conceive, that they were notfoaddm, but fome Sallies , or Pro* 
minencies in that Belt ; which he was induced to believe, becaufe 
he perceived. not, that thztProminency , which he there faw,was fo 
black, nor fo round as CaJJini had reprefented his Jpot-s , where- 
fore, feeing it but little differing in colour, from the Belt, and fo 
not judging it round 5 becaufe it did hand only about half its dia« 
meter out of the Belt , he perfuaded himfelf, that it was rather a 
Sally, or Prominency of the Belt , than a round Jhadorv , as that of a 
Satellite of Jupiter muff have bin. But having been fince infornir 
ed of all the Obfervations made by CaJJini and Campani , with the 
New Glaffes, and feen his Figure , he candidly and publickly 
wilheth,that he had not fpoken of that Sally, or Prominency 5 ad- 
vowing that he can doubt no longer^but that it was the Jhadsw of 
the Satellit between Jupiter and the Sun , having feen the other 
emerge, as foon as with a 20. foot Glafs he made the Obfervati- 
on,and having not perceiv’d th tftjhadows with' a 1 2. foot Glafs : 
But although he grants that they did ghefs better than he,yet ha 
doth it with this provifo , vid. in cafe they made that Obfervati- 
0 not July 90. not with their 36. but 12. or 17. foot Telefcope. 
If it be wondred at, that Monffeur dusyut did not fee this Jh'a- 
dow move, he allegeth his indifpofition for making long Ob/erva.- 
tions , and addeth,that it may be much more wondred at,that nei- 
ther Campani nor himfelf did fee upon the obfcure Belt the Bo- 
dies of the Satellites ,as parts more Luminous than the Belt. For 
(faith he)although the Latitude was Meridional, it being no more' 
than of 9. or io.minutes,the Body of the Satellites fhould, thinks 
he, pafs between m and the Belt, efpecially according to Campa - 
w,whomaketh the Belt fo large, and puts th o /Isadoras farr enough 
within the fame. This maketh him conclude, that either they 
have not obferved well enough, or that the motion of the Sat el, 
lites doth not exa< 5 tly follow the Belts , and is inclin’d unto their?*' 
Whereupon he refolves,that when he (hall know that they are to 
pafs between Jupiter and m, and to be over againft the Belt, that
