The following pages are intended as a help to the young student of geology, who is usually bewildered by the abundance of invertebrate fossils when he first commences collecting them himself. There are books of a much higher and more extensive character, such as the treatises on Palaeontology by Owen and Nicholson, to which I am hopeful this present volume will prove introductory.
I have not attempted to introduce the student to other than invertebrate fossil animals, not only because these are by far the most numerous, but also because such an attempt would have expanded the volume beyond due limits.
I have recollected the nature of the difficulties which beginners in fossil-collecting feel, and have tried to meet them. My hope has been rather to whet the appetite than to satisfy it.
