Now, I'm certain they're both grammatically correct, but I'm curious of their usage; 'various of' seems rather archaic (it's used in Politics and the English Language by Orwell, for example). So, I presume it's either an archaic use, or the British use.
Can anyone tell me which?
I list below, with notes and examples, various of the tricks by means of which the work of prose-construction is habitually dodged.
From George Orwell's "Politics and the English Language". He uses the word 'various' only twice in this essay, both of which precede the preposition 'of'.
