Slight scan failure in Google Books, from The marvellous and incredible adventures of Charles Thunderbolt, in the moon, Charles Rumball, 1851, between pages 189 and 190. (I found it by accident while Googling for literary cheesemites thus).
Coo: I feel like the brother of Jared. I'd never run into it before, but it happens occasionally: see Google Books adds hand scans at TechCrunch. The pink finger cots appear to be standard kit for the job.
