Rationally extended stellar envelopes - HD 109378 (kappa Dra) and 142926.

The atmospheres of the stars HD 109378 and HD 142926 are analysed by the method described in Paper I. New high resolution spectrographic and spectrophotometric observations are presented and calculations made of strong absorption and emission line profiles. Both stars show evidence of gravity darkening in accordance with the predictions of Roxburgh and Strittmatter, and both stars have extended envelopes of lower temperature but similar stmcture to Cas. Models for the envelopes are presented, with values of i and the mass-loss phenomenon is discussed further.
