Other Universe detected!

Our valuable equipment has detected another Universe, bigger than our own! Unit 17∆b has been found in a place he calls 'London'. Pronounciation: Lun-dun. Isn't it strange that 'London' is an anagram of our city, Onlond? There are dangerous beasts living there, such as poisonous reptiles and swamp gas creatures. Unit 17∆b has sent us a radio signal all about it. This other Universe seems a lot bigger than our own. All the better to conquer and civilise!
