mers of Paris ; but it was seen in several parts of France, 

 Observed in Germany, Holland, and Italy. In America it would be 

 particularly interesting, as at Boston and Albany it was to- 

 tal. At Kinderhook, near Albany, it was observed by 

 Mr. Ferrer with excellent instruments. He concluded the 

 conjunction to be at 45 min. S3 sec. after 11. Mr. Lalande 

 found precisely the same : and as he learned by other obser- 

 vations, that it happened at 30 min. 6 sec. after 4 at Paris, 

 it follows, that the difference of longitude of these two 

 places must be 7h, 15' 27" of time. 



The eclipse was observed at Albany too, but at the in- 

 stant of the return of the light the observer had not his eye 

 at the glass : and though this phenomenon would appear to 

 be of a nature to be seen as accurately with the naked eye, 

 it seems to have been noticed a few seconds too late. 

 Disk 'of the A curious remark of Mr. Ferrer is, that the disk of the 



ftomYts atmos- moon appeared illumined a few seconds before the end of 

 phere. the total eclipse, which seemed to him an effect of the at- 



mosphere of the moon.

The sun mov- Many astronomers have supposed, that the sun is notira- 

 able in space, movable in space. Mr. Lalande conjectured from its ro- 

 tatory motion, which is unquestionable, that it has a move- 

 ment of revolution. What he suspected Herschel has en- 

 deavoured to prove by observations. Mr. Pre"vot, of the 

 academy of Petersburg, has been led to the same result : 

 but Mr. du Sejour, having treated the question analytically, 

 has found, that it is insolvable when considered in its to- 

 tality. The results to which Mr. Herschel has been led by 

 the apparent motions of different stars* do not accord suffi-
