We find that the number of C stars in NGC 205 is low (∼500) for its luminosity and that very few C stars are seen outside of the 10 isophote, suggesting tidal stripping by M31. Their <MI≥-4.54, a magnitude nearly identical to what has been found in other galaxies with numerous C stars. Stars with accurate (R-I) photometry, to I∼22.5, are used to determine the outer profile of NGC 205. Description: The results are based on images obtained with the CFH12K mosaic in 2000 September. The camera consists of a 12000x8000 pixel mosaic covering a field of 42'x28', each pixel corresponding to 0.206". Images were obtained through Mould I (2x400s) and R (3x400s) filters and CN (3x700s) and TiO (3x700s). In spite of very good seeing (0.8"), sky conditions during the observations were nonphotometric.
