Neither of those provinces have any science in any other category, though. Each of them would surely put something in alchemy, at the very least. So something like:
25 Scientists:
7 in Alchemy
6 in Crime
12 in Channeling
40 Scientists:
10 in Alchemy
5 in Pop
12 in Crime
13 in Channeling
I don't know the bonuses per scientist off the top of my head, but it doesn't strike me that the second province is going to be so much better than the first that nothing else matters.
