ered, we find that the asteroid nearest the sun is (72), with a mean rig 
2'14 and a period of 1148 days. The asteroid most aac from the 
le, with a mean distance 3°43, and a period of 2322 days, The 
orbit of (72) is therefore nearer to that of Mars than to that of Cybele. 
The asteroid whose orbit has the least excentricity is Concordia, its ex- 
satity being 0-04; that whch has vs greatest, excentricity is Poly-
