The full 12th edition translated into english by David Heaf (one of the more prominent modern day users of the the warré hive.)
The book covers a bit of beekeeping basics, Warré's analysis of some of the different hives of his time, a few interesting observations of bee behaviour in addition the specifications and rational behind his own hive design. Many interesting things in here even if you are an experienced beekeeper with no interest in using a warré hive.
If you assume it's not possible to put natural comb without frames in an extractor have a look at page 63.
In the 5th edition warré discussed the option of using frames in his style of hive.
There's another video in which David Heaf goes through the different pieces used in this hive and some of his construction methods that is worth watching as well:
