Introduction

T N the Author’s earlier works, written only for the youthful student in Science, a promise was made that other books, to be regarded as a series of steps in Science, should be forthcoming.

It is with this view that the present volume is offered ; and as the general reader— in fact, “the Public” — has not the time or the inclination to study the very minute and laborious works of Gmelin, Watt, Miller, and other learned authors, it is hoped that the facts contained in this more advanced but still elementary work will be found sufficiently attractive to stimulate, at all events, the would-be philosopher to further reading, and especially to perform correct scientific experiments.

Brevity and simplicity have been carefully attended to in the following pages; and when other authors are quoted, the writer has preferred giving their exact language, instead of altering and paraphrasing words, which frequently detracts from the sense of the passage.

The reader will find portions of valuable papers written by

Faraday, Daniell, Wheatstone, Brewster, Tyndall, Crookes, Browning, Siemens, Noad, Stewart, Tait, Marloye, and others, with a brief summary of Photography by John Spiller, Esq.

In a work like this, including such a multiplicity of subjects, the kind indulgence of the reader is invoked for any errors that the most painstaking supervision may have permitted to pass.

gUbkation.

I dedicate this work, with all kindly feelings, to those students at Harrow, Eton, Hayleybury, and Cheam, to whom, under the auspices of the Rev. Drs. Vaughan, Goodford, Hawtrey, Butler, Bradby, and Tabor, I have addressed many lectures on Science.

I believe and trust that those lectures have not been altogether unfruitful ; but that they have aided in the establishment of regular science classes for the present generation, instead of the desultory lectures at rare intervals to which custom formerly condemned the teachers of popular science.
