  We report total abundances and related parameters for the full sample of the
FUSE survey of molecular hydrogen in 38 translucent lines of sight. New results
are presented for the "second half" of the survey involving 15 lines of sight
to supplement data for the first 23 lines of sight already published. We assess
the correlations between molecular hydrogen and various extinction parameters
in the full sample, which covers a broader range of conditions than the initial
sample. In particular, we are now able to confirm that many, but not all, lines
of sight with shallow far-UV extinction curves and large values of the
total-to-selective extinction ratio, $R_V$ = $A_V$ / $E(B-V)$ -- characteristic
of larger than average dust grains -- are associated with particularly low
hydrogen molecular fractions ($f_{\rm H2}$). In the lines of sight with large
$R_V$, there is in fact a wide range in molecular fractions, despite the
expectation that the larger grains should lead to less H$_2$ formation.
However, we see specific evidence that the molecular fractions in this
sub-sample are inversely related to the estimated strength of the UV radiation
field and thus the latter factor is more important in this regime. We have
provided an update to previous values of the gas-to-dust ratio, $N$(H$_{\rm
tot}$)/$E(B-V)$, based on direct measurements of $N$(H$_2$) and $N$(H I).
Although our value is nearly identical to that found with Copernicus data, it
extends the relationship by a factor of 2 in reddening. Finally, as the new
lines of sight generally show low to moderate molecular fractions, we still
find little evidence for single monolithic "translucent clouds" with $f_{\rm
H2}$ $\sim$ 1.
