Capt. Kater's Experiments for determining the Variatimi 
Bj comparing the observations of each station successively 
with those at all the others. Captain Kater obtained the results 
in the following Table, containing the diminution of gravity, 
and the resulting compression deduced, in a way which is fully 
explained in the paper itself. — See Phil. Trans. 1819., p. 420,
