I've only read the first Nocturn - three psalms - of Friday Matins from my new Breviary, and I find, twice:
Ant. 3 Ianuas cæli aperuit * Dominus, et pluit illis mana [sic] ad manducandum.
Ant. Ianuas cæli aperuit Dominus, et pluit illis mana [sic] ad manducandum.
[Breviarium Romanum, Nova et Vetera ed., Volume II, pages 547 and 548.]
At least manna is spelt correctly in the psalm itself (Ps 77:24)!
Bizarrely this reminds me of my recent reading of James Belich's Making Peoples: A History of the New Zealanders from Polynesian Settlement to the End of the Nineteenth Century (which I would thoroughly recommend as a very learned and enjoyable read), since the Maori regarded the search for mana (roughly, prestige) as all-important; a sort of "keeping up with the Joneses" exercise.
But I must away, I'm consulting a climatologist...
