</div>I have a copy of the Nadeau (1993 edition) - he has the same English text as
Peter sent earlier, with a reference to English patent No.2,815 dated Dec
13th, 1855 and with the comment "this may be the first time that this patent
is reproduced verbatim".

He also quotes in full Poitevin's first (French) patent no. 24,592 dated
August 27, 1855.

It looks as though this was a privately published book, which might explain
why it isn't on the web.

Best wishes

Hence, the full transcription has to be in Nadeau's book, which I
