We must briefly but warmly commend Dr. J. R. Tanner's

Constitutional Ddcuments of the Reign of James I (Cambridge University Press, 16s.), which continues his well-known collection of Tudor documents. The selection is judicious, the extracts are substantial, and the commentary is precise and accurate. History becomes much more real when it is studied in the original sources, but it may be said that not all "source books are as attractive and trustworthy as Dr. Tanner's. His sections on the religious controversy—not forgetting James's "No Bishop no King "—and on the financial troubles of the Crown are particularly interesting.
