found to be much narrower than at tho^e periods ; his path being now much 

 more oblique in respect of the earth. 



An Account from Paris, in two Letters to the Editor, dated July 5 

 and July 19^ 1670, concerning the earlier Discovery of the same 

 New Star, which is described in the preceding Letter. iV" 65, p. 2092. 



The letter of July 5, 1670, states, that a Carthusian of Dijon, on the 20th 

 of December, 1669, discovered a star of the third magnitude, beneath the 

 head of Cygnus, situated in the section of the two straight lines, one of 

 which goes from Lyra to the nearest of the quadrangle in the Dolphin, 

 and the other from the Eagle to the star which is on the top of the upper wing 

 of Cygnus. 



That of July IQ, 1670, gives this account, viz. That there was much con- 

 versation at Paris about the new star near the beak of Cygnus first discovered 

 by a Carthusian of Dijon, called Anthelme, who sent the news of it to 

 M. L'Abbe Mariotte, one of the Royal .Academy there, who had communi- 

 cated it to the rest : that they all agree, it is a new star ; though Mons. B. 

 opposed it at first, affirming it to be in Bayer's tables. They prove also the 

 star in Bayer to be another ; giving, for distinction, these measures :

Some Communications, confrming the present Appearance of the 

 Ring about Saturn. By M. Huygens and Mr. Hook. N" 65, 

 p. 2093. 



The former writes, in a letter dated the Hague, Oct. 31, 1670, n. s. That 

 he observed Saturn with his telescope of 22 feet, a little before he came out of 

 France, which was the last summer of this year 1670, and saw his figure to 

 be quite conformable to what it should be according to his hypothesis ; viz. 

 the ansae or arms to be very narrow, so that their opening appeared but very 

 obscurely. .
