out the 20 of _December_; and that also very exact Observation
might be made of the time of its being again in _Quadrat_ with the _Sun_,
which, according to him, was to be _January_ 16.

He wishes also, that some in _Madagascar_ may have observed this Star;
Seeing that it began to appear over the middle of that _Island_, and passed
twice over their heads; he judgeth, that they have seen it before us. And
he wisheth lastly, that there were some intelligent person in _Guiana_ to
observe it there, seeing that within a few daies, according to his
reckoning, it will pass over their Heads, and will not remove from thence
but 8 or 10 degrees Northward, where he saith, it will disappear; thinking
it improbable, that it can still appear, after the _Sun_ shall have passed
it.

This Account beareth date of the 2. _January_, new stile, 1665. and the
Author thereof addeth this Note, That, seeing it could not be printed nor
distributed so soon as he desired, he hath had the opportunity to verifie
it by some Observations, from which he affirms he hath found no sensible
difference; or, if there be, that it proceeds only from thence, that the
Stars have advanced, since his _Globe_ was made. He concludeth, that if
this continue, and the first Observations do likewise agree, or that the
differences do arrive within the Times ghessed by him, that he hopes, he
shall determine both the _Distance_ and the _Magnitude_ of this _Comet_;
and that perhaps one may be enabled to decide the Question of the _Motion
of the Earth_. In the interim, he assureth, that he hath not changed the
least number in his Calculations, and that _Monsieur Huygens_, and several
French Gentlemen, to whom he saith, he hath given them long since, can bear
him witness that he hath done so; as also many other friends of his, who
saw upon his _Globe_, several daies before, the way of the _Comet_ from day
to day.

Thus for the _Parisian_ Account of the Comet, which is here inserted at
large, that the intelligent and curious in _England_ may {8} compare their
Observations therewith, either to verifie these _Praedictions_, or to shew
wherein they differ; which is (as was also hinted above) the design of this
_Philosophical Prophet_ in dispersing his Conceptions, who declareth
himself ready, in case he be mistaken in his reckoning, to learn another
_Hypothesis_, to explicate these admirable appearances by.
