Reading this month's Fortean Times I see that the young Barbara Woodhouse encountered an impossible marsupial skunk. She described it as "identical with the skunk picture in Cassell's Book of Knowledge". Karl Shuker asks if someone can find the skunk picture in the Book of Knowledge, to make some sense of this. Luckily, I have a Book of Knowledge. I search for skunk in the index, and find it is under fur on page 1530. I turn to page 1530: someone has cut out the illustration. Obviously, they don't want us to know.
