There are several references in the book to Nabisco wafers. Our belief is that Lovelace was referring to a predecessor of what you now call Nilla Wafers (a cookie adored by the junior members of my household!) but then it was mentioned that one of the references is to Nabisco wafers, "the kind with chocolate on top." Someone else commented that perhaps it was the sugar wafer type of cookie, but then we realized that doesn't have chocolate on the top but in the middle.
We know there are far more important matters in life than researching great cookies of the past, still this is one of those things that just sort of nags at you and you keep wondering and wondering about it. So I decided I might just as well write a letter. The worst that can happen is no one will respond and a bunch of people at Nabisco headquarters will think there is a group of certifiables out there. But on the other hand, you may have someone deep in the arcana lore of Nabisco cooky-ana who can satisfy our curiosity on this.
If you think bribery would help, there are over 1,000 of us.In return for solving this burning question, we would all vow to be undying Nabisco fans forevermore.

There were two versions of the chocolate -- two wafers with chocolate filling between and a chocolate enrobed style. Either could have been the cookie referred to in the literature.
I hope this archivist's research helps your cause.
