Equivalent widths of lines with λ > 4600 Å were measured from a set of 4.5 Å mm^(-1) Palomar plates and were used in performing a model-atmosphere abundance analysis of the mild subdwarf µ Cas. Comparison with the Sun was made by computing abundances from individual solar lines using the same set of transition probabilities as was used for the subdwarf. Results of this analysis show that the iron-peak elements appear to be deficient by a factor of 4, while the α process in µ Cas elements may be enhanced with respect to these elements.
