The first entries I found underlined in my copy of Don B. Johnson's "Worlds in Regression", concerning the Index in SM, were in Section One, chapter "The alphabetic rainbows of Speak,Memory" ( pages 19/21).

"We initiated our discussion of color spectra by suggesting a connection with synesthesia. There is, of course, no necessary tie between the two phenomena. The association is justified only insofar as we can show them to be linked in Nabokov's mind. THE EXPANDED 1966 ENGLISH VERSION OF NABOKOV'S MEMOIRS 9 BUT NOT THE EARLIER ENGLISH OR RUSSIAN VARIANTES0 HAS AN INDEX WHICH IS, AT CERTAIN POINTS, AS MUCH AESTHETIC AS PRACTICAL... We find, among others, the following: Colored hearing, STained glass, Jewels and Pavilion, as well as Magic Lantern and Mushrooms. Most of the constituent elements which enter into the rainbow motif are given, althourh there is no index entry for Rainbow...The reader qho consults Colored hearing is referrred to Stained glass and thence to Jewels and Pavilion. The Jewels entry, via cross reference, leads the reader back to Stained glass... The associational chain establishes the connection between the elements of the rainbow motif and synesthesia...".

In DBJ's introduction he describes how each
"Nabokov novel contains at least two fictive worlds. This "two world" model accounts ( in a formal sense) for much of what happens in many Nabokov novels. It describes their underlying cosmology..."

This matter, as it is developed along his book, reminds us that the doubling found in R.L.Stevenson's J&H novel is not as central to Pale Fire as Carolyn Kunin suggests, since it fits into a more general pattern of a "two world model ..and underlying cosmology"... In that sense, probably "J&H" are only one more item instead of definite clues for the plot of PF.
