Abstract
Differential Stromgren uvby photometric observations from the 0.75-m F our College Automated Photoelectric Telescope were obtained for three metallic-line and three Mercury-Manganese stars. None were found to be variable. These sharp-lined stars may not be the best tests for class variability as their polar axes are pointed towards the earth. Each p resents essentially the same visible hemisphere as it rotates.
