New values of the atmospheric parameters of Cnc are derived. From spectroscopic analysis of very high S/N, high resolution spectra, we obtain: K, (cgs), km s-1, and [Fe/H] . This temperature estimate is consistent with other recent determinations by Gonzalez and Fuhrmann et al.
We have also derived CNO abundances and set a new upper limit on the lithium abundance of . From an analysis of the CN bands near 8000 Å, we set a lower limit on the 12C/13C ratio of 30.
