It is found that Hβ, He II λ4686 and [O III] λλ4959, 5007 emission lines in the spectrum of nova HR Del had in 1981 four-component structure as they did earlier. A comparison with 1968-1978 spectra reveals the changes in relative intensities of the internal and external components of these lines. It is concluded that time variations of physical conditions occur in some condensation in the envelope of HR Del.
