Mifcellanea Curiofa. 1 9 



to die, thefe Papers might be loft, which 

 every Man is not capable to retrieve, by rea- 

 fon of the great Difficulty of the Calculation. 

 Now, it may not be amifs to put the Reader 

 in mind, That our Five firft Comets, (the 

 Third and Fourth obfervd bj Peter jfyia^ the 

 Fifth by Paulas Fabrkitis) as alfo the Tenth feen 

 by M<efilw, if I miftake not, in the Year 1 596. 

 are not fo certain as the reft ; for the Obferva- 

 tions were made neither with fit Inftruments, 

 nor due Care, and upon that Account are dif- 

 agreeing with themfelves, and can by no means 

 be reconcil'd with a regular Computation. The 

 Comet which appear'd in the Year 1684. wa $ 

 only taken Notice of by f Blanch mm , who obfer- 

 vq& at Rome: And the lift, which appear'd in 

 the Year 169$. was feen qnly by thofe at Pa- 

 ris, who determin'd its Courfe in a very un- 

 common Way. This Comet was very obfcure; 

 and, altho' it mov\i fwift, and came near e- 

 nough our Earthy yet we, who are wont to 

 be curious enough in thefe Matters, faw no- 

 thing of it For want of Obfervations I have 

 left out of the foregoing Catalogue, thofe Two 

 remarkable Comets which have appear'd in this 

 our Age, one in November, in the Year 1689 the 

 other in February in the Year 1 702. For they di- 

 recting their Courfesto wards the Southern Parts 

 of the World, and being fcarce confpicuous here 

 in Europe, met with no Obfervers capable of the 

 Buflnefs. But, if any one fhall bring from India, 

 or the Southern Parts, an accurate Series of re- 

 quilite Obfervations, 1 will willingly fall to work 

 again, and undergo the Fatigue of reprefent- 

 ing their Orbits in Numbers, as I have done 

 the reft.
