There is a small bug in equations.sty.  The \lefteqn command is
ignored.  Without using equations.sty, the following example prints as
I would expect from p. 50 of the latex manual: the first line is
shoved over to the left while the second is centered.  However, with
equations the R_c is aligned with -19.9---as if \lefteqn were not
there at all.  I would appreciate any fixes or hints for this problem.
Thanks.

Equations.sty implements several useful equation making environments.
This is the only bug I've found in a very good package.

\begin{eqnarray}
\label{eqn:F2nd}
\lefteqn{R_c \approx R_{c\circ} + 24.6(\epsilon_1 \epsilon_2)
	+ 10.2(\epsilon_1 - \epsilon_2)^2} \\
	& & - 19.9\epsilon_2(\epsilon_1 \rho/\rho_s - \epsilon_3) \nonumber
\end{eqnarray}
