Zacli on Repealing Circles. 363 



in tlie years 1 809 to 1813 mclusive, we made more than 8000 

 observations at Marseilles and in the South of France with 

 this same circle of Reichenbach ; but we will only refer to those 

 which we have already pubhshed either in our Correspondance 

 Astronomique Allemande, or in our work L' Attraction des 

 MoTitagnes, Sfc. 



The table of the observations is as follows : 



It appears by this expose, that in 3262 observations, not se- 

 iected, made with a small 12-inch repeating circle of Reichen- 

 bach, the greatest difference in these observations, from day to 

 day, never extended beyond 4" in the altitudes ; but if we seek 

 these differences in a combination of the series, they never ex- 

 ceeded two seconds.
