liflied, that on the 30/day o(July, i6^s^] at 2~ of the dock in 
the morning, he had obferv'd, with CampanVs Glaffcs, that 
there pafled through the broad dbicmcBeh oi Jupiter two oh- 
fcurer fpHj^hy him eftcemed to be the /hadom of the Satellites^ 
moving hetv/QQuJtipiterSc the5«i^,and eclipfing him^and emerg- 
ing from the Occidental Brim thereof: This J uihour did ^ill 
conceive, that they were notT^^^^??^/, butfome S allies, or Pro^ 
minencies in that Belt ; which he was induced to believe, becaufe 
he perceived not^that thatPrcfT^/^^^a^j/, which he there faw^was fo 
black, nor fo round as Cajftni had reprefented his fpQts 5 where- 
fore, feeing it bat little differing in colour^ from the Belt^ and fo 
not judging it round^becaufe it did ftand only about half its dia^^ 
meter out of the Belt, he perfuaded himfelf^ that it was rather a 
Sallyy or Prominency of the Bslt^ than a round7?^^rf^n?,as that of a 
Satellite of Jupiter muft have bin. But having been fince inform- 
ed of all the 0 b few attorn m^ide by Cajfmi and Campani, with the 
New GlaffeSj and feen his Figt^re, he candidly and publickly 
wifliethjthat he had not fpoken of that Sally, or Prominency , ad- 
vowing that he can doubt no longcr^but that it was the Jhadm of 
the Satellit between Jupiter and the Sun^ having feen the other 
emerge, as foon as witli a 20, foot Glafs he made the Obfervati- 
on^and having not perceived thefe fljadows with a 1 2. foot Glafs - 
But although he grants that they did ghefs better than he^yet he 
doth it with this/?rflz///<9, vid. in cafe they made ^Ac?^ Obfervati- 
on oi July 50. not with their ^c^. but iQ.or i jAool Telefcope. . 
If itbe wondredat, that Monfieur du^ut did not fee thisyfc^- 
dovo move, he allegeth his indifpofition for making long Ohjerva^ 
tions^md addechjthat it may be much more wondred atjthat nei- 
ther f^^/'^wi nor himfelf did fee upon the obfcure B^/^ 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 lo-minut^s^the Body.of the Oiould, thinks 
he, pafs between m and the Bslt, efpecially according to Ccmpa- 
Wjwhomaketh the j^^// fo large,and puts the /^xWeip/ 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 exadly follow the Belts, and is inclined unto them. 
Whereupon \x% refo!ves,that when he lliall know that they are ra
