Lh definition

The coffee plantations were greatly injured by a severe hurricane which visited the island on the 8th of August 1899, but the yield for export increased from 12,157,240 lb in 1901 to 38,756,750 lh, valued at $4,693,004, in 1907.

In the case of the parabolic trapezette, for instance, xu is of degree 3 in x, and therefore the first moment is lh(xouo+4xlui-+x2u2).

Hence Simpson's formula applies, and the volume is lh(A0-I-4A1+ A2).
