Sectarians generally dread meeting a "Mormon" Elder in discussion, for they well know the humiliating defeat which has been the result to their compeers in hundreds of instances.

But there is another class of persons who often bring formidable-looking arguments against the truths of the gospel. This class is composed frequently of persons of considerable learning, research and intelligence. They have long ago become disgusted with the absurdities of so-called Christianity; and are not slow in showing the disagreement of sectarian dogmas with the teachings of the Bible, or contrasting the Bible with supposed science. In some instances, otherwise valuable scientific works are marred by sneers at the books of inspiration. In this age of earnest thought and research into all branches of knowledge, many of these works fall into the hands of the young and hence the growth of skepticism in the minds of many. Many of the facts contained in this work have been collected from, and references made to larger works not easily accessible to the general reader. A large number of the illustrations have been designed expressly for this work, and engraved by Brother John Held, of Salt Lake City.

To gather into a small compass the leading arguments of infidel writers, and to refute them by well-known facts; to show the cause of the conflict between science and religion; and to harmonize true science with the teachings of God's word, has been the design in writing this little work. That in its perusal the young may find their faith strengthened in the principles of the gospel; thoughtful minds find food for reflection, and the missionary Elder a valuable book of reference, is the earnest wish of
