This is a remarkable book. And some of the words are truly disturbing. I remember one referred to a particularly gruesome effect of extreme constipation that still makes me queasy. (I seem to have blocked the word itself, thankfully.)
I'm really looking forward to getting a copy of this. Co-authored by Ammon Shea, who recently read the OED cover to cover, if you can believe that. I'll be talking to him about it for an upcoming Errata post.
