Photoelectric photometry is used to determine the abundances, temperatures, and membership criteria of 22 stars in the Galactic clusters NGC 1261, NGC 6541, and NGC 7099. No evidence for a metallicity spread is found in any of the clusters, although possible CN-strength variations are detected among the NGC 6541 giants. The mean cluster abundances derived are -0.92 + or - 0.25 for NGC 1261, -0.99 + or - 0.2 for NGC 6541, and -1.81 + or - 0.15 for NGC 7099. The values for NGC 1261 and NGC 7099 are found to be in agreement with previous estimates. The value for NGC 6541, however, suggest that it is much more metal rich than other studies have indicated. If the abundance found for this cluster is correct, NGC 6541 would be an extreme example of the second-parameter phenomenon. Further metallicity determiniations for NGC 6541 are recommended.
