Fifteen years ago there appeared a volume of some four hundred pages, which bore the modest title, An Outline of Christian Theology. It had originally been prepared by the author, a professor in Hamilton Theological Seminary, for the use of his seminary classes, and, after circulating for some time in the form of typewritten notes, was privately printed for the greater convenience of the users. No attempt was made to advertise the book, but in due time it found its way into the hands of one and another who was interested in theological questions, and when in 1898 it was issued by the author through the ordinary channels, it received from the public an instant and hearty welcome.
