Robert, who ACTUALLY wrote this in A&ST, please?
I forgot too. Read my very relevant on-line article on this subject;
I think this is absolutely wrong.
"Greek Letter Designations of Southern Stars". 
IMO. The Cross as a separate constellation at least 200 years before this!!
If you were to say who the first to list the stars as a separate constellation, I would say it was Nicolas Louis de Lacaillé 1751-52 - but
officially it was the IAU in 1930.
