He finds, its apparent Motion was not made in a Jh^ great 
Circle, but deviating confiderably from it 5 and conceives^ 
that every Gonaet falls to this deviation^ when this apparent 
Motion grows floWjand the Star becomes Stationary (which^ 
as he faith) it doth in relpeftof the EcUftick^^ not its own 
Orbitc*) Here he obfervesj That from Dere^k .^g.to Decern.

then it began to defleft from that Circle towards the North 2 
fothat afterwards, with a very notable and coofpieuoiis 
Gurvity, it direfted its courfe towards rrhmm Arietis : Of 
which deflcftion, he ventures to affign the caufefrom the 
Cometical Matter, the various pofition and diftance of the 
Gomet from the Earth and theSun^ the annual Motion of 
the Earthj and the imprefled Motion^ and the inclination 
of the difcHs of the Cometical Body- 
He is pretty pofitivej that v?\tho\xtxhe amud Motion oi 
Earthy no rational Account can be given of anyGomctj 
but that all is involved with perplexities^ and deform 'd by 
^bfurdities. 
He inquires, finceallComets have their peculiar Ingenitc 
Motion? what kindeof Line it is, they defcribe by that 
Motion of their own ^ whether circular j or ftreight, or 
curve, or partly ftreightand partly curve And if curve^ 
whether regular or irregular? if regular, whether Elliptick^ 
or Parabolar, or Hyperbolical ? Heanfwers, That this Mo- 
tion is Conical 5 and judgethj that by the Comch^ path all 
the Vh^nomcHA of Comets can, without any inconveniencj'^ 
be readily folved 3 even of that^ which Tby Hiftoryj in fifty 
daysj paffed through more then the i » Signs of the Zodidckj 
And of that, which in two days run through eight Signs : 
and of another, which in 48 days pofted through all the 
Signs, contra feriem. Which how it can be explicated upon 
the fuppofition of the Earths landing ftillj and upon the 
denying of the annual Motion thereof^ he underftands not 
at all.
