Abstract: The first forty-one coefficients of a continued fraction for $ \ln \;\Gamma (z) + z - (z - {\raise0.5ex\hbox{$\scriptstyle 1$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}})\;\ln \;z - \ln \sqrt {2\pi } $ , are given. The computation, based on Wall's algorithm for converting a function's power series representation to a continued fraction representation, was run on the algebraic manipulation system MACSYMA. $ ^{\ast \ast}$
