662 PHILOSOPHICAL TRANSACTIONS, [aNNO 1683. 



omentum lying in a heap on the right side ; it had not recovered its natural 

 posture, since it was put up with the guts at the first opening ; the edges of the 

 wound were well grown together; in short we did not find any thing that 

 seemed to intimate the least want, or to supply the place of the caecum. 



A short Account of three Conjunctions of the Planets Saturn and Jupiter , ob- 

 served at Dantzic, from the end of the Year l682 to May 28, N. S. of 1 683. 

 By M. Hevelius. Translated and abridged from the Latin. N° 151, p. 325. 



On Oct. 26, N. S. l682, at lh.40m. in the morning, taking the situation 

 of Saturn and Jupiter with my tube and micrometer, when a remarkable fixed 

 star was near them, being, I think, that in the right shoulder of $| ; three of 

 Jupiter's satellites, if not the fourth also, being present. The distances taken 

 were, between Saturn and Jupiter 16' 44'', between Saturn and the star 38' I", 

 and between Jupiter and the star 27' 55^''; the star being then, according to our 

 catalogues, in 1 9" 2' g" of ^, with 20' 45^' north latitude. On Oct. 30, at 5h. 

 in the morning, the distance of Saturn and Jupiter was found 25' 5". Whence 

 it may be concluded, that the conjunction happened several days sooner than 

 Nov. 3, when it is given by the ephemeris and the calculation. This will be 

 still farther evinced by the following observations. For if the conjunction were 

 near, the distance of Saturn and Jupiter would daily decrease, whereas it conti- 

 nually increased. Thus, on Nov. 2, I observed their distance 35' 21^'; Nov. 3, 

 at ih. in the morning, it was 39' 9"; and Nov. 4, it was still greater. 

 , As to the other conjunction, which, according to the almanacs, ought to 

 happen by the retrogressions of those planets, on Jan. 26, this year l683, the 

 following are some of the principal observations.

 position with regard to the near stars. And the same will farther appear by
