Further investigations are made into the forms of the coupled equations that govern the propagation of electroacoustic waves in an isotropic, stratified, compressible plasma. First‐order equations are considered in a more suitable notation than hitherto, and then the embedded form and the second‐order forms are derived that are valid throughout domains containing certain reflection and coupling points. Limitations of the W.K.B. solutions are pointed out, thereby correcting rather extravagant claims that have been made previously.
