Incidentally, this copy of FT also filled in a blank regarding a scene in Terry Pratchett's Discworld novel Unseen Academicals. There is a scene in a department of Unseen University (which deals with weird things) where the wizards are apprehensive as to whether the squid has escaped again, is blocking a corridor, and needs to be recaptured. This mental image is left unexplored and unexplained, comes out of nowhere, and just seems to be there for its inherent weirdness and absurdity.
On page 62 of the current FT424, there is a long reply from Bob Rickard where he is describing one of those eccentrically managed British academic institutions, the Natural History Museum. The sort of place that Terry would have gleefully drawn on when creating that most eccentric and nutty haven of academia called Unseen University.
Bob describes a visit where the Department's pet octopus kept escaping from its tank, could be found determinedly escaping down the corridor, and needed to be retrieved and re-incarcerated.
It is just possible that Professor Pycraft and the fish department of the NHM were part of the inspiration for Unseen University on the Discworld! (And a big sub-theme of UU involves pies, of the edible sort....)
