As to the books you speak of: Mastricht is sometimes in one volume, a very thick, large quarto; sometimes in two quarto volumes. I believe it could not be had new under eight or ten pounds. Turretin is in three volumes in quarto, and would probably be about the same price. They are both excellent. Turretin is on polemical divinity; on the Five Points, and all other controversial points; and is much larger in these than Mastricht; and is better for one that desires only to be thoroughly versed in controversies. But take Mastricht for divinity in general, doctrine, practice, and controversy; or as an universal system of divinity; and it is much better than Turretin or any other book in the world, excepting the Bible, in my opinion.
