  A recent publication (J.D. Anderson et. al., EPL 110, 1002) presented a
strong correlation between the measured values of the gravitational constant
$G$ and the 5.9-year oscillation of the length of day. Here, we provide a
compilation of all published measurements of $G$ taken over the last 35 years.
A least squares regression to a sine with a period of 5.9 years still yields a
better fit than a straight line. However, our additions and corrections to the
G data reported by Anderson {\it et al.} significantly weaken the correlation.
