It is still extant. There was an original typescript, complete with Crowley's hand written annotations, for sale on the Weiser Antiquarian website not so long ago.
Unfortunately my pockets were not deep enough.
Ah, I seem to remember that, yes. A typescript (I have a hard time imagining Crowley typing; I'm thinking dictation while reading from a manuscript).
If we presume this typescript was Crowley's last edit before sending to the printers, we should assume that his annotations were incorporated into the final text. This means that "compromised in the series" is either a typesetter's mistake, the original typist's mistake which Crowley overlooked, a *secondardy* typist's mistake on the final copy, or, finally, Crowley's intended words, which nevertheless make no sense.
I guess, if someone were really ambitious, they could try to find who owns it and ask that specific question.
