OR, RUDIMENTS OF THE SCIENCE APPLIED TO EVERY-DAY LIFE. BY ALBERT J. BERNAYS, Ph.D., F.C.S., AUTHOR OF LECTURES ON AGRICULTURE, ETC. THIRD EDITION. CONSIDERABLY ENLARGED. LONDON: SAMPSON LOW & SON, 47, LUDGATE HILL. 1854. 193. 2. 3. ΤΟ THE REV. L. J. BERNAYS, M.A. THIS LITTLE WORK, CONTAINING THE SUBSTANCE OF LECTURES DELIVERED AT ELSTREE SCHOOL, Es Dedicated, WITH MUCH AFFECTION, BY HIS BROTHER, PREFACE TO THE THIRD EDITION. THE fact of the sale, within less than two years, of two large editions of his little work, is sufficient evidence that there was a demand for a book of its character, which the author had endeavoured, as the result has shown, not quite unsatisfactorily to supply. Nevertheless, while most grateful for the kindness with which "HOUSEHOLD CHEMISTRY, OR THE CHEMISTRY OF EVERY-DAY LIFE," had been received by the press and the general public, the author conceived it to be his duty, in preparing for publication another edition, in the form he intended it finally to assume, to make it, as far as he could, more worthy of the favor it had hitherto enjoyed. The alterations which he considered it desirable to make, together with circumstances not within his control, have combined to delay the publication of this edition; but the author trusts that the delay has not been without advantage to his work. The whole has been revised, and the Appendix entirely rewritten; while the addition of numerous illustrations is calculated to render the book more popular and generally useful. Imperfect as the work undoubtedly remains, the author trusts it may be found a useful manual of the chemistry of common life. DERBY, June, 1854. |
