That students of the Analogy need help, is confessed; and all attempts to furnish it have been kindly received. As is remarked by Bishop Wilson, “His argument, clear and convincing as it is to a prepared mind, is not obvious to the young reader, whose experience of life being small, and his habits of reflection feeble, has not the furniture necessary for comprehending, at first, the thoughts and conclusions of such a mind. The style is too close, too negligent, too obscure, to be suitable for the young.”

If it be asked why, with several existing helps to the study of the Analogy, I offer another, I frankly reply, because I have found none of them satisfactory, either to the public or to myself.


Some teachers prefer their text-books to be accompanied by a set of questions. Such will find in this edition all they desire. They have only to enunciate each sentence of the Conspectus in the interrogative form, and they will have every possible question prepared to their hand.
