Within the framework offered by the commonly accepted model of Beta-Lyrae as a close binary with an envelope, spectral changes may be interpreted as the result of the envelope's influence on the spectrum of the primary. Attention is given to the high members of the Balmer hydrogen series in an effort to study the most stable profiles possible, but changes with phase are found in the high members as well. Superior abundance values may be obtainable through a computation of the model atmosphere that takes into account the common envelope of the entire system, as well as processes taking place in its vicinity.
