 periments on the fall of bodies, which £ 

 noticed laftyear. He has found a devia- 

 tion of 12| millimetres in 8G metres ; 

 but the extremes ditfer 6 millimetres, on 

 account of the great ditiiculty of the ob-

 No one was ever better acquainted with 

 the Indians, ancient and modern, than the 

 Academicians of Calcutta. AcconliuH-
