There's a good example of what I mean at http://explorer.lib.uiowa.edu/ch1/images/p019a.gif

Hard to tell from a small sample, but perhaps Baskerville?

Edit: There are a ton of Baskerville digitizations out there - I have Monotype Baskerville but I noticed this new one, called John Baskerville which seems very complete.

I agree that it looks like Baskerville, but the clincher would be to see a Q. I'd guess in that time period the Monotype might have been the model for most of them, but I think every foundry had their own versions. You are talking about metal type, remember, probably set by something like a Linotype or Monotype typesetting machine.

A look at McGrew might give a good idea what was in use.

Thanks. Also, what about the sans serif font that's there? Anyone have an idea what that is?

Looks like Futura Bold.

Actually, I think it is Futura Bold, after comparing it with Futura Book.
