I had been hoping to get some more information about this thesis, but with no luck so far. So as I had started this particular hare, I will comment.
Unfortunately. I did not keep a record of the source for this reference., but ISTR that it was a list of theses on literature from an English (country) web site. As has been stated, there is no record of it via the Aberdeen University library. I have emailed the English department, but so far have had not reply.
The MLitt is a taught degree with a dissertation. Subject to getting a reply, my speculation is that (a) this was a thesis that was announced but abandoned, or (b) that it is ongoing and therefore has not hit the formal reporting system, or (c) something else.
Subject to further information, I have now flagged this as a probable 'ghost' reference.
Searches around Aberdeen have not be entirely fruitless, as I did find some other references to alchemy.
