PREFACE.

The worker in any department of science, if he keeps abreast with its progress, has usually some discovery to announce, some paper to read, or some address to deliver. Of such miscellaneous matterselected chiefly with a view to instruction in the

Principles of Geology—the present volume is in a a great measure composed. What has been of interest

to the few, may often, with slight modification, be made attractive to the many; and in particular to those who, having no need, and indeed no time, for systematic training in science, are yet desirous to become acquainted with its more prominent facts and bearings. This is all the Author aims at by the publication of these “ Chips and Chapters," and he will be specially gratified should they fulfil the end intended, or aid in any way the young geologist to a

clearer comprehension of his subject. The field of Geology is a wide and varied one, and whatever may help to a sounder appreciation of its importance, or induce another labourer to enter, however trivial it may appear to the practised worker, should at least have the opportunity of doing so by being put in the requisite form and addressed to the proper quarter.
