TO MY FATHER,

J. H. COLLINS, F. G. S.,

PAST-PRESIDENT OF THE INSTITUTION OF MINING AND METALLURGY,

&c., &c., &c.,

I am indebted for an early training in those branches of Natural and Applied Science, of which he himself has been an earnest student and an accomplished teacher. For this early training I can never be sufficiently grateful, and to it must in justice be attributed such measure of success as I may hereafter achieve. To my father, therefore, this book is (without permission) dedicated by

THE AUTHOR.
