The illustration here given of the Digestive Apparatus of man represents the organs of food digestion, especially the alimentary canal and glands connected therewith, and to the reader of this book, or to any student of anatomy, it will be found of invaluable service as a reference.

The diagram gives a view of the digestive organs from the ventral or front side, a proper study of which cannot fail to impress every intelligent being with the reverential deduction of the Psalmist that we are “_fearfully and wonderfully made_.”
