We present the results of a search in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ for anomalous production of events containing a photon and a lepton ( $e$ or $\ensuremath{\mu}$), both with large transverse energy, using $86{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected with the Collider Detector at Fermilab during the 1994--1995 collider run at the Fermilab Tevatron. The presence of large missing transverse energy ( ${E}_{T}$), additional photons, or additional leptons in these events is also analyzed. The results are consistent with standard model expectations, with the possible exception of photon-lepton events with large ${E}_{T}$, for which the observed total is 16 events and the expected mean total is $7.6\ifmmode\pm\else\textpm\fi{}0.7$ events.
