Spectroscopic methods were used to monitor the Hα and Hβ indices for two emission-line objects, X Persei and γ Cassiopeiae. The spectroscopic data covered a timeline from 2010 to 2020. The Hα index for X Per showed substantial variation, with the Hβ index changes being less pronounced. The shape of the Hα variations for X Per were a mirror image to archival V-magnitude observations. In the case of γ Cas only a slight rise in value for the Hα index was seen. To allow comparison to published observations, we determined a transformation from the two indices to equivalent width values. The values determined for X Per fill time gaps in the previously published equivalent width values. The γ Cas values provide no additional coverage.
