 Schubert on the obliquity of the ecliptic. N. 



A. Petr. 1792. X. 433. 



Schubert finds the mean obliquity of the ecliptic 24° 1 1'; 

 its limits 20" 34', and 27° 48': thatitwill continue to di- 

 minish for 4900 years, and will then be 22° 53' ; but he 

 observes that some little inaccuracy has been introduced 

 into the calculation, the mass of Venus having been made 

 too great.
