Speck, resplendent like Gold, and encompassed
with another more dilute and seemingly uniform matter: its _Tail_ being at
first, about 17. deg. and afterwards 20. and sometimes 25 deg. long, and
divaricated towards the End.

_Next_, it is observed, that though this Star did afterwards slacken its
pace, yet it retained the vividness of its Colour, both of the _Head_ and
_Train_; the _Head_ especially, keeping at the time as well of the last
observations, as of the {302} first, the brightness of its single _kernel_,
though the environing more dilute matter were then almost all lost; it
being, according to the Author, more and more attenuated, and grown narrow,
the nearer the Star approached to the Sun.

_Thirdly_, 'tis noted, That this _Comet_ did very much digress from the
_Hypothesis_, delivered by _M. Auzout_, in regard that, whereas according
to that _Hypothesis_, this Star should not arrive to the _Ecliptick_ till
after the space of 3 months, it arrived there the 28 of _April_. And then,
that its first Conjunction with the Sun hapned between the 19 and 20 of
_April_, and the second, the last of _April_, not (as _M. Auzout_, would
have it) the 15 of _May_. So that he concludes, that this Comet never came
down to the _Pleiads_ and the _Eye of Taurus_, as the Hypothesis of _M.
Auzout_ requires, but that from _April_ 20. it did immediately take its
course towards the Ecliptick, deflecting every day more and more from the
_Section_ of a _Great Circle_, to the _Lucida_ of _Aries_, arriving at the
_Ecliptick_ the last of _April_, about the 8th or 10th deg. of _Taurus_;
not in _July_ about the 8th of _Gemini_, and the _Eye of Taurus_.

_Fourthly_, He intimates, that if this Comet had appeared some weeks
sooner, it would have confronted the former Comet, being yet in its vigour
and of a conspicuous bigness, in the same place, where that was, viz. the
_Head of Aries_.

_Fifthly_, He observes, that this Star in progress of time became
_Retrograde_, whence it came to pass, that in the Months of _June_ and
_July_ it did not appear again before the Rising of the Sun, though the Sun
left it far behind: whereas, if it had proceeded toward the _Eye of
Taurus_, it would have appeared again in the morning.

_Sixthly_, He maintains, that this Comet was not the same with the former;
which he thinks may be demonstrated, onely by a due Delineation of both
their Course upon the _Globe_; where he saith it to be evident, that the
former c
