Christian Teaching of Coin Mottoes. By Dr. Wm. Allan and

Prof. J. Zimmerman. (S.P.C.K. 3s. 6d.)—The history naturally begins with the fourth century of our era—such things could hardly have existed before—though there is an instance of a Christian emblem on a coin produced about A.D. 270. Later on they become more and more frequent. The authors of this volume have collected much curious information which will well repay study.
