The Netu Comet. 3^7 



" The longitude of it« ascending node is 253". 13'. 50". 

 " That ef the perihelion on the orbit . 92». 58'. 30". 

 " Its inclination ou the ecliptic . . . 74*. aO'. 30". 



'^ The motion of the comet is direct : in adtlition to its 

 slow motion, it affords a remarkable uniformity in longitude 

 and latitude ; and these two circumstances have rendered 

 the calculations more difficult of execution. 



*' It approaches the earth very slowly. There are some 

 days when we know its place in the heavens, and when the 

 absence of the moon admits of our observing it, on which 

 it may be seen with the naked eye : its tail is nearly two 

 degrees long. It may appear striking to those who shall 

 be able to choose a convenient time and place for observing 

 it; but whatever may be the favourable circumstances un- 

 der which it presents itself to our vision in France, it is far 

 from being so luminous as the comet of last year. But this 

 is of little consequence to astronomers, who do not found 

 their observations upon the fugitive characters which attend 

 these phaenomena. The comet in question was at first seen 

 and calculated upon v/ithout a tail, and might have dis- 

 appeared in this state without causing the least regret among 

 astronomers. If they now pursue its progress until it 

 disappears, it will only be to perfect its elements, and to 

 ascertain if their series of observations furnishes any index 

 on the subject of its revolution." 



A private letter from the environs of Mount Caucasus 

 conveys the following intelligence : — *' It has been long 

 known that the rich inhabitants and invalids of Russia used 

 to frequent the hot springs of Caucasus, and that they were 

 in great' repute. They suddenly disappeared in the month 

 of March last, and re-appeared in April upon the ridge of 

 the mountain, but in much greater quantity, and much 

 hotter than before ; but not a drop was to be found in the 

 site occupied by the former buildings. The springs dis- 

 appeared without any earthquake or other perceptible 

 phaenomcnon. New bath-houses have been hastily con- 

 structed where the springs now flow."
