ADA: "She could recollect, of course, when she and her sister played ‘note-comparing,’ much better than Lucette ...;but Lucette, though so much younger, remembered heaps of bagatelles, little ‘turrets’ and little ‘barrels,’ biryul’ki proshlago. She was, cette Lucette, like the girl in Ah, cette Line (a popular novel), ‘a macédoine of intuition, stupidity, naïveté and cunning.’(ch 24)

Ada On Line:  138.13-14: Oh! qui me rendra mon Aline / Et le grand chêne et ma colline?: Darkbloom: “oh who will give me back my Aline, and the big oak, and my hill?” Note the changes Van rings on the final sestet: Hélène becomes Aline, perhaps to emphasize the personal tang of Chateaubriand’s poem, since his elder brother, Jean-Baptiste Auguste de Chateaubriand, married in 1787 Aline-Thérèse Le Pelletier de Rosanbo; both died under the guillotine in 1794. Cf. also: “She was, cette Lucette, like the girl in Ah, cette Line (a popular novel),” 152.09-10.

from BB's On line Notes on Ch24:  152.10-11: like the girl in Ah, cette Line (a popular novel): A tease.  Presumably a pun on acetylene (“Colorless and explosive, like some  popular novels,” suggests Mary Krimmel on NABOKV-L, April 20, 2005)   and on the feminine name Aline, but the “popular novel” has not been  identified.  Carolyn Kunin notes (NABOKV-L, April 20, 2005) that in 1895, “Henri  Moissan discovered that calcium carbide and water produced acetylene gas, and burning acetylene produced light. For the next ten years,  acetylene producers flourished until the lower cost of electric and  coal gas lighting collapsed the acetylene market.” Now Lucette means  “little light.” If acetylene is a precursor or surrogate for  electricity in light generation (as Nabokov knew: see the “carbide  lamps” at 154.23 and n.), such as would be permissible in Antiterra,  and if the word acetylene is disguised in Ah, cette Line, as the word  electricity is disguised in various ways in Ada (as in “the L  disaster” or “Lettrocalamity”), then Ah, cette Line almost becomes an  image of Ada itself (woman’s name, begins with “Ah” sound, and set on  a world where electricity can’t even be mentioned), but with Lucette  as perhaps its heroine.
