At eight a clock thirty minuts^the fore-edge was in the fame 
horary Circle with the CQnter oi the Sua: So that in one day 
and an half thefe Spots have run through very near the third 
part of the Sun's apparent femi- diameter, which giveth an Arc 
of nineteen degrees and an half of the Circumference of the 
Sun's Body ; and confequently their Diurnal motion about the 
Sun s jixe hath been of thirteen degrees , and the time of their 
Periodical revolution^ as far as we could conjediure in fo little 
time, muft be about twenty /even days and an half : Which yet 
will be more exactly determined by Obfervations of a longer 
time. Mean while thofe that have been made, give us hopes 
to fee them yet fix or feven days longer^ if they diiappear not: 
before they arrive to the Sun's limb. 
We thought it not amifs to advertife thofe^that are addidcd 
to Celeftial Oblervations, of the Difcovery of thefe Phcemme^ 
na^ that they may alfoobferve the fame, and if they be not 
furnifli t with gre^t Telefcopes, they ought not therefore to be 
diverted from It, fince we have found, that by a glafs of one 
foot thefe Spots may be feen, at leaft as making but one fpoc. 
But it will be particularly neceffary, to obferve with care from 
about the fourth unto the eighteenth ^of the aionth of Septem- 
ber next, (ft.n.) whether thefe Spots^ after they have pafled 
over the Upper Hemi-fpere of the Sun which is hid from us, 
will not return and be fcen again in its apparent difque. 
So far the French Academifis^ To which we now add • 
i*Thatfince their Obfervations were made publick, we had 
notice fent us from the above-mentioned Dv.Fo^elius refiding 
at Hamburg^{2i% we touched in the foregoing Trad:^ ) that Mr* 
Ficard h^d obferv'd at Sea a Spot in the Sun from thethird of 
jiuf uji(&,n^) to the nineteenth of the fame inclufively 3 and 
feen ic,ac the firftjlike the Tayl of a Scorpion ; but on the nine* 
teenth day refembling a Melon -feed. 2. That feveral curious 
ObkrvQTs 2t London have feen one of thofe Spots recurr'd to 
the Sun's Eaflern Hmb^on the fame day that Signor Cajfwi pre- 
didied in the Relation above dch*ver*d they fliould return , if 
they continued : The particulars of whole ObfervationS;if they 
come to hand^we may give an account of hereafter^
