This is a training manual from 1937 and is general to all aircraft types of the time, so what it has to do with Merlin engines with 100 octane and +12lbs boost in 1940 is anybody's guess. Anyway I'd really like to see the anecdotes - and I note the word anecdotes - about the +16 lbs on 87 Octane...
